| |
| c++: beware of short ranges for state numbers |
| Now that we use small integral types, possibly unsigned (e.g., |
| unsigned char), to store state numbers, using -1 to denote an empty |
| state (i.e., a state that stores no semantical value) is very |
| dangerous: it will be confused with state 255, which might be |
| non-empty. |
| |
| Rather than allocating a larger range of state numbers to keep the |
| empty-state apart, let's use the number of a state known to store no |
| value. The initial state, numbered 0, seems to fit perfectly the job. |

| c++: get rid of symbol_type::token () |
| It is not used. And its implementation was wrong when api.token.raw |

| Reported by Frank Heckenbach. |
| https://lists.gnu.org/archive/html/bug-bison/2019-11/msg00016.html |
| |
| The cast is needed when yytranslate_'s argument type is token_type, |
| i.e., when api.token.constructor is defined. |
| |
| 373. types.at:138: testing lalr1.cc api.value.type=variant api.token.constructor ... |

| ~ ^ ~~~~~~~~~~~~~~~~~~~~~~ |
| 1 error generated. |
| |
| It is because it is expected that when api.token.constructor is |
| defined, only symbol constructors will be used, that yytranslate_ then |
| takes a token_type. But it is wrong: we still allow literal |
| characters in this case, as demonstrated by test 373 for instance. |
| |
| %define api.value.type variant |
| %define api.token.constructor |
| %token <std::pair<int, int>> '1' '2'; |

| if (res) |
| return symbol (res, std::make_pair (res - '0', res - '0' + 1)); |
| else |
| return symbol (res); |
| } |
| |
| So let yytranslate_ always take an int, which makes the cast truly |
| useless. |

| |
| * data/skeletons/c++.m4 (b4_yytranslate_define): Don't use yyeof_ as |
| if it had two different types. |
| It is used once against the input argument, which is the value |
| returned by yylex, which is an "external token number", typically an |
| int. It is also used as output type, an "internal symbol number". |
| It turns out that in both cases we mean "0", but let's keep yyeof_ |
| only for the case "internal symbol number", i.e., _after_ conversion |
| by yytranslate. |
| This frees us from one cast. |

| yacc.c, glr.c: fix crash when reporting errors in consistent states |
| The current code for yysyntax_error for %define parse.error verbose is |
| fishy (given that YYEMPTY is -2, invalid argument for yytname[]): |
| |
| static int |
| yysyntax_error ([...]) |
| { |
| YYPTRDIFF_T yysize0 = yytnamerr (YY_NULLPTR, yytname[yytoken]); |
| [...] |
| if (yytoken != YYEMPTY) |
| |
| A nearby comment reports |
| |
| The only way there can be no lookahead present (in yychar) is if |
| this state is a consistent state with a default action. Thus, |
| detecting the absence of a lookahead is sufficient to determine |
| that there is no unexpected or expected token to report. In that |
| case, just report a simple "syntax error". |
| |
| So it _is_ possible to call yysyntax_error with yytoken == YYEMPTY, |
| albeit quite difficult when meaning to, so virtually impossible by |
| accident (after all, there was never a bug report about this). |
| |
| I failed to produce a test case, but Joel E. Denny provided me with |
| one (added to the test suite below). The yacc.c skeleton fails on |
| this, and once fixed dies on a second problem. The glr.c skeleton was |
| also dying, but immediately of this second problem. |
| |
| Indeed we were not allocating space for the error message's final \0. |
| This was hidden by the fact that we only had error messages with at |
| least an unexpected token displayed, so with at least one "%s" in the |
| format string, whose size (2) was included (incorrectly) in the final |
| size of the message (where the %s have been replaced by the actual |
| content). |
| |
| * data/skeletons/glr.c, data/skeletons/yacc.c (yysyntax_error): |
| Do not invoke yytnamerr on YYEMPTY. |
| Clarify the computation of the length of the _final_ error message, |
| with the NUL terminator but without the '%s's. |

| doc: don't promote dangling aliases |
| String literals as tokens serve two distinct purposes: freeing from |
| having to implement the keyword matching in the scanner, and improving |
| error messages. Most of the time both can be achieved at the same |
| time, but on occasions, it does not work so well. |
| |
| We promote their use for error messages. We will also still support |
| the former case, but it is _not_ the recommended approach. |
| |
| * doc/bison.texi (Tokens from Literals): Clearly state that we don't |
| recommend looking up the token types in the list of token names. |

| |
| diagnostics: complain about undeclared string tokens |
| String literals, which allow for better error messages, are (too) |
| liberally accepted by Bison, which might result in silent errors. For |
| instance |
| |
| %type <exVal> cond "condition" |
| |
| does not define “condition” as a string alias to 'cond' (nonterminal |
| symbols do not have string aliases). It is rather equivalent to |
| |
| %nterm <exVal> cond |
| %token <exVal> "condition" |
| |
| i.e., it gives the type 'exVal' to the "condition" token, which was |
| clearly not the intention. |

| * src/complain.h, src/complain.c: Add support for -Wdangling-alias. |

| lalr1.cc: use computed state types |
| This skeleton uses a single stack of state structures, so it is less |
| likely to benefit from a stack size reduction than yacc.c (which uses |
| several stacks: state number, value and location). But it will reduce |
| the size of the LAC stack. |
| |
| This skeleton was already using int for state numbers, so, contrary to |
| yacc.c, this brings nothing for large automata. |
| |
| Overall, it is still nicer to make the skeletons alike. |

| c++: port to Sun C++ 5.12 |
| The documentation for Oracle Solaris Studio 12.3 (Sun C++ 5.12 |
| 2011/11/16) says it supports C++03. This compiler rejects the |
| location.cc use of std::max for some reason; I don’t know why |
| since I don’t use C++ as a rule. The simplest workaround is to |
| open-code ‘max’. |
| * data/skeletons/location.cc (add_): |
| Do max by hand rather than relying on std::max. |
| Don’t include <algorithm.h>; no longer needed. |

| to Solaris 10 which is still supported. |

| c: improve port of stdint.h usage to pre-C99 |
| Oracle Solaris Studio 12.3 (Sun C 5.12 2011/11/16) by default does |
| not conform to C99; it defines __STDC_VERSION__ to be 199409L, so |
| the Bison code does not include <stdint.h> (not required by C89 |
| amendment 1) even though this compiler does have <stdint.h>. On |
| this platform <limits.h> defines INT_LEAST8_MAX (POSIX allows |
| this) so the skeleton got confused and thought that <stdint.h> had |
| been included even though it wasn’t. |
| * data/skeletons/c.m4 (b4_c99_int_type_define) [!__PTRDIFF_MAX__]: |
| Always include <limits.h>. |
| (YY_STDINT_H): Define when <stdint.h> was included. |
| All uses of expressions like ‘defined INT_LEAST8_MAX’ changed to |
| ‘defined YY_STDINT_H’, since Sun C 5.12 <limits.h> defines macros |
| like INT_LEAST8_MAX but does not declare types like int_least8_t. |

| * data/skeletons/c.m4 (b4_c99_int_type_define): Reorder to put the |
| signed types first, since they’re simpler and this keeps similar |
| code closer. For signed types, don’t bother checking whether the |
| type promotes to int since the type must be signed anyway. For |
| unsigned types, protect a test like ‘UCHAR_MAX <= INT_MAX’ with |
| ‘!defined __UINT_LEAST8_MAX__’, as otherwise the logic is wrong |
| for oddball platforms; and once we do that, there should no need |
| for ‘defined INT_MAX’ so remove that. |

| |
| There might be something to do in gnulib about this, but I believe |
| that gnulib should not be used in the test suite in the first place. |
| |
| The test suite should work with other compilers than the one used to |
| compile the package. For a start, Bison sources are more |
| demanding (C99) than the generated parsers. Last time I tried, tcc |
| for example, was not able to compile Bison, yet our generated parsers |
| should compile cleanly with it. |
| |
| Besides the problem at hand is with the C++ compiler, with is not the |
| one used to set up gnulib at configuration-time (config.h is mainly |
| built from probing the C compiler). |
| |
| We should really not depend on gnulib in tests. |
| |
| This was introduced in 2001 to check whether including |
| stdlib.h/string.h is safe thanks to STDC_HEADERS |
| (2ce1014469742b5c6618daf8506b69e38787c7d5). Today, we assume at least |
| a C90 compiler, it should be safe enough. |
| |
| * tests/local.at, tests/testsuite.h: Do not include config.h. |
| * tests/atlocal.in (conftest.cc): Likewise. |
| (CPPFLAGS): Do not expose lib/, as because of this we might picked up |
| gnulib replacement headers for system headers. |

| |
| Use “least” types for integers in Yacc tables |
| This changes the Yacc skeleton to use “least” integer types to |
| keep tables smaller on some platforms, which should lessen cache |
| pressure. Since Bison uses the Yacc skeleton, it follows suit. |
| * data/skeletons/yacc.c: Include limits.h and stdint.h if this |
| seems to be needed. |
| (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): |
| If available, use GCC predefined macros __INT_MAX__ etc. to select |
| a “least” type, as this avoids namespace hassles. Otherwise, if |
| available fall back on selecting a “least” type via the C99 macros |
| INT_MAX, INT_LEAST8_MAX, etc. Otherwise, fall further back on one of |
| the builtin C99 types signed char, short, and int. Make sure that |
| any selected type promotes to int. Ignore any macros YYTYPE_INT16, |
| YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8 defined by the user. |
| (ptrdiff_t, PTRDIFF_MAX): Simplify in the light of the above. |
| (yytype_uint8, yytype_uint16): Do not assume that unsigned char |
| and unsigned short promote to int, as this isn’t true on some |
| platforms (e.g., TI TMS320C55x). |
| * src/parse-gram.y (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16) |

| diagnostics: sort symbols per location |
| Because the checking of the grammar is made by phases after the whole |
| grammar was read, we sometimes have diagnostics that look weird. In |
| some case, within one type of checking, the entities are not checked |
| in the order in which they appear in the file. For instance, checking |
| symbols is done on the list of symbols sorted by tag: |
| |
| foo.y:1.20-22: warning: symbol BAR is used, but is not defined as a token and has no rules [-Wother] |
| 1 | %destructor {} QUX BAR |
| | ^~~ |
| foo.y:1.16-18: warning: symbol QUX is used, but is not defined as a token and has no rules [-Wother] |
| 1 | %destructor {} QUX BAR |
| | ^~~ |
| |
| Let's sort them by location instead: |
| |
| foo.y:1.16-18: warning: symbol 'QUX' is used, but is not defined as a token and has no rules [-Wother] |
| 1 | %destructor {} QUX BAR |
| | ^~~ |
| foo.y:1.20-22: warning: symbol 'BAR' is used, but is not defined as a token and has no rules [-Wother] |

| |
| style: simplify the handling of symbol and semantic_type tables |
| Both are stored in a hash, and back in the days, we used to iterate |
| over these tables using hash_do_for_each. However, the order of |
| traversal was not deterministic, which was a nuisance for |
| deterministic output (and therefore also a problem for tests). So at |
| some point (83b60c97ee1f98bb1f15ffa38acdc4cc765515f5) we generated a |
| sorted list of these symbols, and symbols_do actually iterated on that |
| list. But we kept the constraints of using hash_do_for_each, which |
| requires a lot of ceremonial code, and makes it hard/unnatural to |
| preserve data between iterations (see the next commit). |
| |
| Alas, this is C, not C++. |
| |
| Let's remove this abstraction, and directly iterate on the sorted |
| tables. |
| |
| * src/symtab.c (symbols_do): Remove. |
| Adjust callers to use a simple for-loop instead. |
| (table_sort): New. |
| (symbols_check_defined): Use it. |
| (symbol_check_defined_processor, symbol_pack_processor) |
| (semantic_type_check_defined_processor, symbol_translation_processor): |
| Remove. |
| Simplify the corresponding functions (that no longer need to return a |
| bool). |

| |
| The current approach, with location_caret_suggestion, is fragile: |
| there's a protocol of calls to the complain functions which is strict. |
| We should rather have a richer structure describing the diagnostics, |
| including with submessages such as the suggestions, passed in the end |
| to the routines in charge of formatting and printing them. |

| Prefer signed to unsigned integers |
| This patch contains more fixes to prefer signed to unsigned |
| integer types, as modern tools like 'gcc -fsanitize=undefined' |
| can check for signed integer overflow but not unsigned overflow. |

| |
| yacc: use the most appropriate integral type for state numbers |
| Currently we properly use the "best" integral type for tables, |
| including those storing state numbers. However the variables for |
| state numbers used in yyparse (and its dependencies such as |
| yy_stack_print) still use int16_t invariably. As a consequence, very |
| large models overflow these variables. |
| |
| Let's use the "best" type for these variables too. It turns out that |
| we can still use 16 bits for twice larger automata: stick to unsigned |
| types. |
| |
| However using 'unsigned' when 16 bits are not enough is troublesome |
| and generates tons of warnings about signedness issues. Instead, |
| let's use 'int'. |

| |
| diagnostics: learn how to count column number with multibyte chars |
| So far diagnostics were cheating: in addition to the 'column' field of |
| locations (based on actual screen width per multibyte characters and |
| on tabulation expansion), the scanner sets the 'byte' field. |
| Diagnostics used this byte count to decide where to insert (color) |
| style. |
| |
| We want to be able to truncate the quoted lines when there are too |
| wide to fit the screen. This requires that the diagnostics learn how |
| to count columns, the byte-in-boundary trick no longer works. |
| |
| Bytes are still used for fix-its. |
| |
| * bootstrap.conf: We need mbfile for mbf_getc. |
| * src/location.c (caret_info): We need an mbfile. |
| (caret_set_file): Initialize it. |

| |
| diagnostics: style: rename member for clariy |
| * src/location.c (caret_info): Now that we no longer have a 'file' |
| member (see previous commit), rename 'source' as 'file'. |
| |
| 2019-09-22 Akim Demaille <[email protected]> |
| |
| diagnostics: style: use a boundary to track the caret_info |
| * src/location.c (caret_info): Replace file and line with pos, a |
| boundary. This will allow us to use features of the boundary type, |
| such as boundary_compute. |
| |
| 2019-09-22 Akim Demaille <[email protected]> |
| |
| diagnostics: extract boundary_compute from location_compute |
| The handling of the contributions of the tabulations in the columns is |
| burried inside location_compute. We will soon be willing to use the |
| boundary part of the computation (to compute the current column number |
| each time we read a multibyte char). |

| Bison used to feature %raw, documented as follows: |
| |
| @item %raw |
| The output file @file{@var{name}.h} normally defines the tokens with |

| internal Bison numbers are used instead. (Yacc-compatible numbers start |
| at 257 except for single character tokens; Bison assigns token numbers |
| sequentially for all tokens starting at 3.) |
| |
| Unfortunately, as far as I can tell, it never worked: token numbers |
| are indeed changed in the generated tables (from external token number |
| to internal), yet the code was still applying the mapping from |
| external token numbers to internal token numbers. |
| |

| diagnostics: beware of unexpected EOF when quoting the source file |
| When the input file contains lone CRs (aka, ^M, \r), the locations see |
| a new line. Diagnostics look only at \n as end-of-line, so sometimes |
| there is an offset in diagnostics. Worse yet: sometimes we loop |
| endlessly waiting for \n to come from a continuous stream of EOF. |
| |
| Fix that: |
| - check for EOF |
| - beware not to call end_use_class if begin_use_class was not |
| called (which would abort). This could happen if the actual |
| line is shorter that the expected one. |

| |
| diagnostics: beware of unexpected EOF when quoting the source file |
| When the input file contains lone CRs (aka, ^M, \r), the locations see |
| a new line. Diagnostics look only at \n as end-of-line, so sometimes |
| there is an offset in diagnostics. Worse yet: sometimes we loop |
| endlessly waiting for \n to come from a continuous stream of EOF. |
| |
| Fix that: |
| - check for EOF |
| - beware not to call end_use_class if begin_use_class was not |
| called (which would abort). This could happen if the actual |
| line is shorter that the expected one. |
| |
| Prompted by a (private) report from Marc Schönefeld. |

| lalr1.cc: add LAC support |
| Implement lookahead correction (LAC) for the C++ skeleton. LAC is a |
| mechanism to make sure that we report the correct list of expected |
| tokens if a syntax error occurs. So far, LAC was only supported for |
| the C skeleton "yacc.c". |
| |
| * data/skeletons/lalr1.cc: Add LAC support. |
| * doc/bison.texi: Update. |
| |
| 2019-08-09 Adrian Vogelsgesang <[email protected]> |
| |
| style: readability improvements to yacc.c |
| * data/skeletons/yacc.c (yysyntax_error): Change the nesting of `m4` |
| conditions slightly to make it more readable. |
| The generated C code stays unchanged. |
| |
| 2019-08-09 Adrian Vogelsgesang <[email protected]> |
| |
| lalr1.cc: reduce "scope" |
| * data/skeletons/lalr1.cc (yy_lr_goto_state_): Make it static. |

| lalr1.cc: fix indentation of table declarations in the header |
| * data/skeletons/lalr1.cc: Fix indentation of table declarations in |
| the generated header. |

| |
| tests: prepare LAC tests for more languages |
| * tests/regression.at: Use %expect to avoid warnings. |
| Set the keywords to facilitate running specific tests. |
| Use macros such as AT_YYLEX_DECLARE to facilitate tests for other |
| languages. |
| Likewise for AT_FULL_COMPILE. |

| diagnostics: use the modern argmatch interface |
| * src/complain.h (warnings): Remove Werror. |
| Adjust dependencies. |
| Sort. |
| Remove useless comments (see the doc in argmatch group). |
| * src/complain.c (warnings_args, warnings_types): Remove. |

| doc: avoid spurious empty lines in the option table |
| In Texinfo. empty lines in multitable rows generate empty lines in the |
| output. Avoid them altogether. |
| |
| With help from Gavin Smith. |
| https://lists.gnu.org/archive/html/bug-texinfo/2019-07/msg00000.html |
| |
| * build-aux/cross-options.pl: Separate rows with empty lines. |
| So, to be more readable, generate a single line for each row. |
| Use Perl format to this end. |
| |

| |
| --fixed-output-files: detach from --yacc |
| See the previous commit. This option should be removed, -o suffices. |
| |
| * src/getargs.c (FIXED_OUTPUT_FILES): New. |
| Add support for it. |
| (getargs): Define loc, and use it. |
| This is safer when we need to pass a pointer to a location. |
| |
| 2019-07-07 Akim Demaille <[email protected]> |
| |
| %fixed-output-files: detach from %yacc |
| The name fixed-output-files is pretty clear: generate y.tab.c, as Yacc |
| does. So let's detach this from %yacc which does more: it requires |
| POSIX Yacc behavior. |
| |
| This directive is obsolete since December 29th 2001 |
| 8c9a50bee13474c1491df8f79f075f5214dda0d1. It does not show in the |
| doc. I don't want to spend more time on improving its diagnostics, it |
| could be removed just as well as far as I'm concerned. |
| |
| * src/scan-gram.l, src/parse-gram.y (%fixed-output-files): Detach from |
| %yacc. |

| doc: remove the --report=look-aheads alias |
| Years ago we moved from 'look-ahead' to 'lookahead', and that alias |
| was kept for backward compatibility. But now that we use argmatch to |
| generate the documentation, that value clutters the doc. |
| |
| * src/getargs.c (argmatch_report_args): Remove the |

| gnulib: use new features of the argmatch module |
| It can now generate the usage message. |
| |
| * src/complain.h (feature_fixit_parsable): Rename as... |
| (feature_fixit): this, for column economy. |
| Adjust dependencies. |
| (warning_usage): New. |
| Use it. |
| * src/complain.h, src/complain.c, src/getargs.h, src/getargs.c: |
| Use ARGMATCH_DEFINE_GROUP instead of the older interface. |

| See https://lists.gnu.org/archive/html/bison-patches/2019-06/msg00012.html. |

| (position::toString): Don't print empty file names. |

| (location::toString): Match the implementations of C/C++. |
| (yy_semantic_null): Leave undefined, the previous implementation does |
| not compile. |
| * tests/calc.at: Improve the implementation for D. |
| Enable more checks, in particular using locations. |

| raw memory is not enough, as exemplified by move-only types. |

| |
| * lib/version-etc.c (version_etc_arn, emit_bug_reporting_address): |
| Move URLs and formatting newlines out of translatable string. |
| |

| gnulib.po. These changes are not yet available on the translation |
| project, so we would have a regression in the set of translated |
| strings. |

| Revert "build: also generate the graph |

| package: don't ship the sources generated from the parser |
| Because some of our examples use |

| Automake ships parse.y and parse.c, and possibly parse.h when it |
| "understands" that there is one. This is not what we want: ship only |
| parser.y. Yet we still want to use Automake to compile the sources |
| from parser.y. The easiest seems to use |
| |
| nodist_%C%_reccalc_SOURCES = %D%/parse.y |
| |
| together with |
| |

| the `./` prefix (see 967a59d2c08a33f24708450561e2f8010b604523). |

| diagnostics: better rule locations |
| The "identifier and colon" of a rule is implemented as a single token, |
| but whose location is only that of the identifier (so that messages |
| about the lhs of a rule are accurate). When reducing empty rules, the |
| default location is the single point location on the end of the |
| previous symbol. As a consequence, when Bison parses a grammar, the |
| location of the right-hand side of an empty rule is based on the |
| lhs, *independently of the position of the colon*. And the colon can |
| be way farther, separated by comments, white spaces, including empty |
| lines. |
| |
| As a result, some messages look really bad. For instance: |
| |
| $ cat foo.y |
| %% |
| foo : /* empty */ |
| bar |
| : /* empty */ |
| |
| gives |
| |
| $ bison -Wall foo.y |
| foo.y:2.4: warning: empty rule without %empty [-Wempty-rule] |
| 2 | foo : /* empty */ |
| | ^ |
| foo.y:3.4: warning: empty rule without %empty [-Wempty-rule] |
| 3 | bar |
| | ^ |
| |
| The carets are not at the right column, not even the right line. |
| |
| This commit passes the colon "again" after the "id colon" token, which |
| gives more accurate locations for these messages: |
| |
| $ bison -Wall foo.y |
| foo.y:2.10: warning: empty rule without %empty [-Wempty-rule] |
| 2 | foo : /* empty */ |
| | ^ |
| foo.y:4.2: warning: empty rule without %empty [-Wempty-rule] |
| 4 | : /* empty */ |
| | ^ |
| |

| we scan it again afterwards. |

| fixits: track byte-columns, not character-columns |
| Because the fix-its were ready the character-based columns, but were |

| %fixed-output-files |

| diagnostics: copy GCC9's format |

| diagnostics: fix the handling of multibyte characters |
| This is a pity: efforts were invested in computing correctly the |

| diagnostics: fix styling issues |
| Single point locations (equal boundaries) are troublesome, and we were |
| incorrectly ending the style in their case. Which results in an abort |
| in libtextstyle. |
| |
| There is also a confusion between columns as displayed on the |
| screen (which take into account multibyte characters and tabulations), |
| and the number of bytes. Counting the screen-column |
| incrementally (character by character) is uneasy (because of multibyte |
| characters), and I don't want to maintain a buffer of the current line |
| when displaying the diagnostic. So I believe the simplest solution is |
| to track the byte number in addition to the screen column. |
| |
| * src/location.h, src/location.c (boundary): Add the byte-column. |
| Adjust dependencies. |

| bison: use no-lines |
| The 'regen' commit in Bison's history are a nuisance. They are |

| tarball. |
| |
| * Makefile.am (AM_YFLAGS_WITH_LINES): New. |
| (AM_YFLAGS): Use it. |

| no-lines: avoid leaving an empty line instead of the syncline |

| |
| java: use full locations for diagnostics about destructors |
| Currently we use the syncline to report errors about a symbol's |
| destructor/printer. This is not accurate (only file and line), and |
| this is incorrect: the file name is double quotes (a recent change, |
| needed to make sure we escape properly double quotes in it). And |
| worst of all: with --no-line, b4_syncline expands to nothing. |
| |
| Rather, push the locations into the backend, and use them. |
| |
| * src/muscle-tab.h, src/muscle-tab.c (muscle_location_grow): Make it |
| public. |
| * src/output.c (prepare_symbol_definitions): Use it to pubish the |

| lalr: don't overbook memory |
| I never understood why we book ngotos+1 slots for relations between |
| gotos: there are at most ngotos images, not ngotos+1 (and "includes" |
| does have cases where a goto is in relation with itself, so it's not |
| ngotos-1). |
| |
| Maybe bbf37f2534a8e5a6b4e28047f0a10903e6dc73f9 explains the +1: a bug |
| left us register a goto several times on occasion, and the +1 might |
| have been a means to avoid this problem in most cases. Now that this |
| bug is addressed, we should no longer overbook memory, if only for the |
| clarity of the code ("why ngotos+1 instead of ngotos?"). |
| |
| * src/lalr.c: A goto has at most ngotos images, not ngotos+1. |

| lalr: fix segmentation violation |
| The "includes" relation [DeRemer 1982] is between gotos, so of course, |
| for a given goto, there cannot be more that ngotos (number of gotos) |
| images. But we manipulate the set of images of a goto as a list, |
| without checking that an image was not already introduced. So we can |
| "register" way more images than ngotos, leading to a crash (heap |
| buffer overflow). |

| style: rename spec_defines_file as spec_header_file |
| The variable spec_defines_file denotes the name of the generated |
| header. Its name is derived from --defines/%defines, whose name in |
| turn is derived from the fact that the header, in Yacc, contained the |
| |
| Not only does the header now contain a lot more than just the token |
| definitions, but we no longer even generate macros, but an enum... |
| |
| Let's modernize our vocabulary. |
| |
| * src/files.h, src/files.c (spec_defines_file): Rename as... |
| (spec_header_file): this. |
| |
| 2019-03-17 Akim Demaille <[email protected]> |
| |
| yacc.c: provide a means to include the header in the implementation |
| Currently when --defines is used, we generate a header, and paste an |
| exact copy of it into the generated parser implementation file. Let's |
| provide a means to #include it instead. |
| |
| We don't do it by default because of the Autotools' ylwrap. This |
| program wraps invocations of yacc (that uses a fixed output name: |
| y.tab.c, y.tab.h, y.output) to support a more modern naming |
| scheme (dir/foo.y -> dir/foo.tab.c, dir/foo.tab.h, etc.). It does |
| that by renaming the generated files, and then by running sed to |
| propagate these renamings inside the files themselves. |
| |
| Unfortunately Automake's Makefiles uses Bison as if it were Yacc (with |
| --yacc or with -o y.tab.c) and invoke bison via ylwrap. As a |
| consequence, as far as Bison is concerned, the output files are |
| y.tab.c and y.tab.h, so it emits '#include "y.tab.h"'. So far, so |
| good. But now ylwrap processes this '#include "y.tab.h"' into |
| '#include "dir/foo.tab.h"', which is not guaranteed to always work. |
| |
| So, let's do the Right Thing when the output file is not y.tab.c, in |
| which case the user should %define api.header.include. Binding this |
| behavior to --yacc is tempting, but we recently told people to stop |
| using --yacc (as it also enables the Yacc warnings), but rather to use |
| -o y.tab.c. |
| |
| Yacc.c is the only skeleton concerned: all the others do include their |
| header. |

| |
| yacc.c: emit the header before the implementation file |
| * data/skeletons/yacc.c: here. |
| This is more logical for the time stamps, but it's also required by |
| following patches: the shared declarations are also in charge of |
| handling api.value.type=union. So far, they are run in the |
| implementation file in both cases (with or without header). But if we |
| run them only in the header, then the implementation file is emited |
| with incorrect support for api.value.type=union. |
| Arguably we should not have such dependencies. This is because we |
| have side-effects in our backend (redefining the symbols' type and |
| type_tag). In the future we should find a better solution for this, |
| without sacrificing the independence of the backend from bison |
| itself (i.e., I don't think we should handle api.value.type=union in |
| bison, leave it to m4). |

| |
| simplify the generated #line |
| Currently we generate things like: |
| |
| #line 683 "src/parse-gram.y" /* yacc.c:316 */ |
| |
| The first part is of course very important: compilers point the users |
| to their grammar file rather than into the generated parser. The |
| second part points to the place in the skeletons that generated this |
| piece of code. |
| |
| This dependency on the Bison skeletons generates lots of useless 'git |
| diff'. This location is useless for the regular user (who does not |
| care about the skeletons) and is actually not useful for Bison |
| developpers too (I never used this to locate the code in skeletons |
| that generated output). So disable it completely. If someone thinks |
| this was actually useful, a %define variable should be provided to |
| control the level of verbosity of '#line', in replacement of |
| --no-lines. |
| |
| So now, generate: |
| |
| #line 683 "src/parse-gram.y" |

| style: clarify the computation of the lookback edges |
| * src/lalr.c (build_relations): Reduce the scopes. |
| Instead of keeping rp alive in two different loops, clarify the second |
| one by having an index on the path we traverse (i.e., use that index |
| to compute the source state _and_ the symbol that labels the |
| transition). |
| This allows to turn an obscure 'while'-loop in a clearer (IMHO) |
| 'for'-loop. We also consume more variables (by introducing p instead |
| of making more side effects on length), but we're in 2019, I don't |
| think this matters. What does matter is that (IMHO again), this is |
| now clearer. |
| Also, use clearer names. |

| doc: a single space before closing comments |
| I don't think this style: |

| /* If buffer is full, make it bigger. */ |
| if (i == length) |
| { |
| length *= 2; |
| symbuf = (char *) realloc (symbuf, length + 1); |
| } |
| /* Add this character to the buffer. */ |

| gram: fix handling of nterms in actions when some are unused |
| Since Bison 3.3, semantic values in rule actions (i.e., '$...') are |
| passed to the m4 backend as the symbol number. Unfortunately, when |
| there are unused symbols, the symbols are renumbered _after_ the |
| numbers were used in the rule actions. As a result, the evaluation of |
| the skeleton failed because it used non existing symbol numbers. |
| Which is the happy scenario: we could use numbers of other existing |
| symbols... |
| |
| Reported by Balázs Scheidler. |
| http://lists.gnu.org/archive/html/bug-bison/2019-01/msg00044.html |
| |
| Translating the rule actions after the symbol renumbering moves too |
| many parts in bison. Relying on the symbol identifiers is more |
| troublesome than it might first seem: some don't have an |
| identifier (tokens with only a literal string), some might have a |
| complex one (tokens with a literal string with characters special for |
| M4). Well, these are tokens, but nterms also have issues: "dummy" |
| nterms (for midrule actions) are named $@32 etc. which is risky for |
| M4. |
| |
| Instead, let's simply give M4 the mapping between the old numbers and |
| the new ones. To avoid confusion between old and new numbers, always |
| emit pre-renumbering numbers as "orig NUM". |
| |
| * data/README: Give details about "orig NUM". |
| * data/skeletons/bison.m4 (__b4_symbol, _b4_symbol): Resolve the |
| "orig NUM". |
| * src/output.c (prepare_symbol_definitions): Pass nterm_map to m4. |

| closure: initialize it once for all |
| The memory allocated by 'closure' (and some data such as 'fderives') |
| is used to computed a state's full itemset from its core. This is |
| needed during the construction of the LR(0) automaton, and the memory |
| is reclaimed immediately afterwards. |
| |
| Unfortunately the reports (graph, text, xml) also need this |
| information when describing the states with their full itemsets. As a |
| consequence the memory was allocated again, fderives computed again |
| too, and more --trace reports are generated which only duplicate what |
| was already reported. |
| |
| Stop that. It does mean that we release the memory later (hence the |
| peak memory usage is higher now), but I don't think that's a problem |
| today. |
| |
| * src/lr0.c (generate_states): Don't call closure_free. |

| lr0: use a bitset for the set of "shiftable symbols" |
| This will make it easier to add new elements (that might already be |

| |
| I could not measure any significant differences in performances in the |
| generation of LR(0) automaton (benched on gramamrs of Ruby, C, and C++). |

| c++: address -Wweak-vtables warnings |
| Reported by Derek Clegg |
| http://lists.gnu.org/archive/html/bug-bison/2019-01/msg00021.html |
| |
| aux/parser-internal.h:429:12: error: 'syntax_error' has no out-of-line virtual |
| method definitions; its vtable will be emitted in every translation unit |
| [-Werror,-Wweak-vtables] |
| struct syntax_error : std::runtime_error |
| |
| To avoid this warning, we need syntax_error to have a virtual function |
| defined in a compilation unit. Let it be the destructor. To comply |
| with C++98, this dtor should be 'throw()'. Merely making YY_NOEXCEPT |
| be 'throw()' in C++98 triggers |
| errors (http://lists.gnu.org/archive/html/bug-bison/2019-01/msg00022.html), |
| so let's introduce YY_NOTHROW and flag only ~syntax_error with it. |
| |
| Also, since we now have an explicit dtor, we need to provide an copy |
| ctor. |
| |
| * configure.ac (warn_cxx): Add -Wweak-vtables. |
| * data/skeletons/c++.m4 (YY_NOTHROW): New. |

| diagnostics: improve the accuracy for %error-verbose |
| Avoid duplicate warnings about %error-verbose, once for deprecation, |
| another for duplicate. Keep only the duplicate warning for the second |
| occurrence of %error-verbose. |
| |
| This will help removal fixits. |
| |
| * src/scan-gram.l (%error-verbose): Return as a PERCENT_ERROR_VERBOSE |
| token. |
| * src/parse-gram.y (do_error_verbose): New. |
| Use it. |
| * src/muscle-tab.c (muscle_percent_variable_update): Handle pseudo |
| variables such as %error-verbose. |

| diagnostics: avoid duplicate warnings for deprecated directives |
| Currently, on |
| |
| %define parser_class_name "Parser" |
| %define parser_class_name "Parser" |
| %% |
| exp:; |
| |
| we issue: |
| |
| foo.y:1.9-25: warning: deprecated directive, use '%define api.parser.class {Parser}' [-Wdeprecated] |
| %define parser_class_name "Parser" |
| ^~~~~~~~~~~~~~~~~ |
| foo.y:2.9-25: warning: deprecated directive, use '%define api.parser.class {Parser}' [-Wdeprecated] |
| %define parser_class_name "Parser" |
| ^~~~~~~~~~~~~~~~~ |
| foo.y:2.9-25: error: %define variable 'api.parser.class' redefined |
| %define parser_class_name "Parser" |
| ^~~~~~~~~~~~~~~~~ |
| foo.y:1.9-25: previous definition |
| %define parser_class_name "Parser" |
| ^~~~~~~~~~~~~~~~~ |
| |
| Let's get rid of the second warning about the deprecated variable |
| parser_class_name. This is noise, but it will also be a problem with |
| fixits for removing duplicates, as we will first generate the update, |
| and then it's too late to remove it: fixits do not edit the result of |
| previous fixits. |
| |
| So generate this instead: |
| |
| foo.y:1.1-34: warning: deprecated directive, use '%define api.parser.class {Parser}' [-Wdeprecated] |
| %define parser_class_name "Parser" |
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| foo.y:2.1-34: error: %define variable 'api.parser.class' redefined |
| %define parser_class_name "Parser" |
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| foo.y:1.1-34: previous definition |
| %define parser_class_name "Parser" |
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| * src/muscle-tab.c (muscle_percent_variable_update): Pass the warning |
| to the caller, instead of issuing it. |
| (muscle_percent_define_insert): Issue this warning only if we don't |
| have to complain about a duplicate definition. |
| * tests/input.at: Adjust expectations. |

| |
| * src/getargs.h, src/getargs.c (update_flag): New. |
| * src/fixits.h, src/fixits.c (fixits_run): New. |
| * src/main.c (main): Invoke fixits_run when --update is passed. |
| * tests/input.at (Deprecated directives): Check --update. |
| |

| |
| diagnostics: improve accuracy for deprecated %define variables |
| * src/parse-gram.y: Use the location of the whole definition to record |
| the location of a %define variable, instead of just the name of the |
| variable. |
| Adjust tests. |
| |
| 2019-01-14 Akim Demaille <[email protected]> |
| |
| diagnostics: keep the fixits |
| Introduce proper support for fixits, instead of just printing them on |
| demand. |
| |
| * bootstrap.conf: We need gnulib's xlists. |
| * src/fixits.h, src/fixits.c: New. |
| * src/complain.c (deprecated_directive): Use fixits_register. |
| * src/main.c (main): Use fixits_free. |

| diagnostics: improve them for %name-prefix |
| Currently the diagnostics for %name-prefix are not precise enough. In |
| particular, they does not show that braces must be used instead of |
| quotes. |
| |
| Before: |
| |
| foo.y:3.1-14: warning: deprecated directive, use '%define api.prefix' [-Wdeprecated] |
| %name-prefix = "foo" |
| ^^^^^^^^^^^^^^ |
| |
| After: |
| |
| foo.y:3.1-20: warning: deprecated directive, use '%define api.prefix {foo}' [-Wdeprecated] |
| %name-prefix = "foo" |
| ^^^^^^^^^^^^^^^^^^^^ |
| |
| To do this we need the value passed to %name-prefix, so move the |
| warning from the scanner to the parser. |
| |
| Accuracy will be very important for the forthcoming changes. |
| |
| * src/parse-gram.y (do_name_prefix): New. |
| (PERCENT_NAME_PREFIX): Have a semantic value: the raw source, with |
| possibly underscores, equal sign, and spaces. This is used to provide |
| a more accurate message. It does not take comments into account, |
| but... |
| * src/scan-gram.l (%name-prefix): Delegate the warnings to the parser. |
| |
| * tests/headers.at, tests/input.at: Adjust expectations. |

| glr.cc: fix the handling of syntax_error from the scanner |
| Commit 90a8537e6287f92fb3d5be0258a69247a742f12e was right, but issued |
| two error messages. Commit 80ef7e7639f99618bee490b2dea02b5fd9ab28e5 |
| tried to address that by mapping yychar and yytoken to empty, but that |
| completely breaks the invariants of glr.c. In particular, yygetToken |
| can be called repeatedly and is expected to return the latest result, |
| unless yytoken is YYEMPTY. Since the previous attempt was "recording" |
| that the token was coming from an exception by setting it to YYEMPTY, |
| instead of getting again the faulty token, we fetched another one. |
| |
| Rather, revert to the first approach: map yytoken to "invalid token", |
| but record in yychar the fact that we come from an exception thrown in |
| the scanner. |
| |
| * data/skeletons/glr.c (YYFAULTYTOK): New. |
| (yygetToken): Use it to record syntax errors from the scanner. |
| * tests/c++.at (Syntax error as exception): In addition to checking |
| syntax_error with error recovery, make sure it also behaves as |
| expected without. |

| This is very debatable. This function is not pure at all, so it could |

| c++: variants: fuse declarations and definitions |
| We used to create a short definition of yy::parser with all the |
| implementations of its member functions outside. But yy::parser is no |
| longer short and simple to read. Maintaining each function twice is |
| painful: a lot of redundancy but different indentation levels, output |
| which depends on whether we are in a header or not (see |
| d132c2d5455135f63a7497c38358eadd6e3a6af8), etc. |
| |
| Let's simplify this and put the implementations into the class |
| definition itself. |

| c++: move stack<T> inside yy::parser |
| We used to define such auxiliary structures outside the class, mainly |
| as a matter of style to keep the definition of yy::parser short and |
| simple. However, now there's a lot more code generated inside the |
| class definition (e.g., all the token constructors), so the |
| readability no longer applies. |
| |
| However, if we move stack (and slice) inside yy::parser, then it |
| should no longer be needed to change the namespace to have multiple |
| parsers: changing the class name should suffice. |
| |
| One common argument against inner classes is that they code bloat. It |
| hardly applies here, since typically different parsers will have |
| different semantic value types, hence different actual stack types. |
| |
| * data/skeletons/lalr1.cc: Invoke b4_stack_define inside yy::parser. |

| |
| c++: exhibit a safe symbol_type |
| Instead of introducing make_symbol (whose name, btw, somewhat |
| infringes on the user's "name space", if she defines a token named |
| "symbol"), let's make the construction of symbol_type safer, using |
| assertions. |
| |
| For instance with: |
| |
| %token ':' <std::string> ID <int> INT; |
| |
| generate: |
| |
| symbol_type (int token, const std::string&); |
| symbol_type (int token, const int&); |
| symbol_type (int token); |
| |
| It does mean that now named token constructors (make_ID, make_INT, |
| etc.) go through a useless assert, but I think we can ignore this: I |
| assume any decent compiler will inline the symbol_type ctor inside the |
| make_TOKEN functions, which will show that the assert is trivially |
| verified, hence I expect no code will be emitted for it. And anyway, |
| that's an assert, NDEBUG controls it. |

| symbols: clean up their parsing |
| Prompted by Rici Lake. |
| http://lists.gnu.org/archive/html/bug-bison/2018-10/msg00000.html |
| |
| We have four classes of directives that declare symbols: %nterm, |
| %type, %token, and the family of %left etc. Currently not all of them |
| support the possibility to have several type tags (`<type>`), and not |
| all of them support the fact of not having any type tag at all |
| (%type). Let's unify this. |
| |
| - %type |
| POSIX Yacc specifies that %type is for nonterminals only. However, |
| some Bison users want to use it for both tokens and nterms |
| (actually, Bison's own grammar does this in several places, e.g., |
| CHAR). So it should accept char/string literals. |
| |
| As a consequence cannot be used to declare tokens with their alias: |
| `%type foo "foo"` would be ambiguous (are we defining foo = "foo", |
| or are these two different symbols?) |
| |
| POSIX specifies that it is OK to use %type without a type tag. I'm |
| not sure what it means, but we support it. |
| |
| - %token |
| Accept token declarations with number and string literal: |
| (ID|CHAR) NUM? STRING?. |
| |
| - %left, etc. |
| They cannot be the same as %token, because we accept to declare the |
| symbol with %token, and to then qualify its precedence with %left. |
| Then `%left foo "foo"` would also be ambiguous: foo="foo", or two |
| symbols. |
| |
| They cannot be simply a list of identifiers, but POSIX Yacc says we |
| can declare token numbers here. I personally think this is a bad |
| idea, precedence management is tricky in itself and should not be |
| cluttered with token declaration issues. |
| |
| We used to accept declaring a token number on a string literal here |
| (e.g., `%left "token" 1`). This is abnormal. Either the feature is |
| useful, and then it should be supported in %token, or it's useless |
| and we should not support it in corner cases. |
| |
| - %nterm |
| Obviously cannot accept tokens, nor char/string literals. Does not |
| exist in POSIX Yacc, but since %type also works for terminals, it is |
| a nice option to have. |
| |
| * src/parse-gram.y: Avoid relying on side effects. For instance, get |
| rid of current_type, rather, build the list of symbols and iterate |
| over it to assign the type. |
| It's not always possible/convenient. For instance, we still use |
| current_class. |
| Prefer "decl" to "def", since in the rest of the implementation we |
| actually "declare" symbols, we don't "define" them. |
| (token_decls, token_decls_for_prec, symbol_decls, nterm_decls): New. |
| Use them for %token, %left, %type and %nterm. |
| * src/symlist.h, src/symlist.c (symbol_list_type_set): New. |
| * tests/regression.at b/tests/regression.at |
| (Token number in precedence declaration): We no longer accept |
| to give a number to string literals. |

| |
| parser: reprecate %nterm back |
| After having spent quite some time on cleaning the handling of symbol |
| declarations in the grammar files, I believe we should keep it. |
| |
| It looks like it's a duplicate of %type, but it is not. While POSIX |
| Yacc requires %type to apply only to nonterminal symbols, it appears |
| that both byacc and bison accept it for tokens too. And some |
| experienced users do actually expect this feature to group |
| symbols (terminal or not) by type ("On the other hand, it is generally |
| more useful IMHO to group terminals and non-terminals with the same |
| type tag together", |
| http://lists.gnu.org/archive/html/bug-bison/2018-10/msg00000.html). |
| Even Bison's own parser does this today (see CHAR). |

| parser: improve the error message for symbol class redefinition |
| Currently our error messages include both "symbol redeclared" and |

| obscure, let's make this clearer. |
| |
| I think the idea between 'definition' vs. 'declaration' is that in the |

| so %nterm would be about declaration. The case of %token is less |
| clear. |

| backend: revamp the handling of symbol types |
| Currently it is the front end that passes the symbol types to the |
| backend. For instance: |
| |
| %token <ival> NUM |
| %type <ival> exp1 exp2 |
| exp1: NUM { $$ = $1; } |
| exp2: NUM { $<ival>$ = $<ival>1; } |
| |
| In both cases, $$ and $1 are passed to the backend as having type |
| 'ival' resulting in code like `val.ival`. This is troublesome in the |
| case of api.value.type=union, since in that the case the code this: |
| |
| %define api.value.type union |
| %token <int> NUM |
| %type <int> exp1 exp2 |
| exp1: NUM { $$ = $1; } |
| exp2: NUM { $<int>$ = $<int>1; } |
| |
| because in this case, since the backend does not know the symbol being |
| processed, it is forced to generate casts in both cases: *(int*)(&val)`. |
| This is unfortunate in the first case (exp1) where there is no reason |
| at all to use a cast instead of `val.NUM` and `val.exp1`. |
| |
| So instead delegate the computation of the actual value type to the |
| backend: pass $<ival>$ as `symbol-number, ival` and $$ as |
| `symbol-number, MULL`, instead of passing `ival` before. |
| |
| * src/scan-code.l (handle_action_dollar): Find the symbol the action |
| is about, not just its tyye. Pass both symbol-number, and explicit |
| type tag ($<tag>n when there is one) to b4_lhs_value and b4_rhs_value. |
| |
| * data/bison.m4 (b4_symbol_action): adjust to the new signature to |
| b4_dollar_pushdef. |

| argument, and use it. |

| casting the union. |
| * data/yacc.c (b4_lhs_value, b4_rhs_value): Accept the new |
| symbol-number argument. |

| warning: avoid warnings about unreachable code |
| Reported by Uxio Prego. |
| https://lists.gnu.org/archive/html/help-bison/2018-11/msg00031.html |
| |
| We also need to move the unreachable 'goto' to a reachable place, |
| otherwise clang complains about the code being unreachable anyway. |
| See also https://bugs.llvm.org/show_bug.cgi?id=39736. |
| |
| Interestingly, we don't have to apply that trick to |
| `#define YYCDEBUG if (false) std::cerr`, clang does not warn when the |
| code comes from macro expansion. |
| |
| * configure.ac: Use -Wunreachable-code when supported. |
| * data/lalr1.cc, data/yacc.c: Pacify clang's warning about `if (0)` |
| by using a macro. |
| Another possibility was to move this statement to a reachable place. |
| * tests/actions.at, tests/c++.at: Avoid generating unreachable code. |
| |
| 2018-11-24 Akim Demaille <[email protected]> |
| |
| yacc.c: avoid generating dead code |
| We should probably introduce some struct and functions to deal with |
| stack management, rather than open coding it. yyparse would be much |
| nicer to read, and a better model for possible other skeletons. |

| * data/yacc.c (yyparse::yysetstate): Avoid generating code when |

| |
| allow %expect and %expect-rr modifiers on individual rules |
| This change allows one to document (and check) which rules participate |
| in shift/reduce and reduce/reduce conflicts. This is particularly |
| important GLR parsers, where conflicts are a normal occurrence. For |
| example, |
| |
| %glr-parser |
| %expect 1 |
| %% |
| |
| ... |
| |
| argument_list: |
| arguments %expect 1 |
| | arguments ',' |
| | %empty |
| ; |
| |
| arguments: |
| expression |
| | argument_list ',' expression |
| ; |
| |
| ... |
| |
| Looking at the output from -v, one can see that the shift-reduce |
| conflict here is due to the fact that the parser does not know whether |
| to reduce arguments to argument_list until it sees the token AFTER the |
| following ','. By marking the rule with %expect 1 (because there is a |
| conflict in one state), we document the source of the 1 overall shift- |
| reduce conflict. |
| |
| In GLR parsers, we can use %expect-rr in a rule for reduce/reduce |
| conflicts. In this case, we mark each of the conflicting rules. For |
| example, |
| |
| %glr-parser |
| %expect-rr 1 |
| |
| %% |
| |
| stmt: |
| target_list '=' expr ';' |
| | expr_list ';' |
| ; |
| |
| target_list: |
| target |
| | target ',' target_list |
| ; |
| |
| target: |
| ID %expect-rr 1 |
| ; |
| |
| expr_list: |
| expr |
| | expr ',' expr_list |
| ; |
| |
| expr: |
| ID %expect-rr 1 |
| | ... |
| ; |
| |
| In a statement such as |
| |
| x, y = 3, 4; |
| |
| the parser must reduce x to a target or an expr, but does not know |
| which until it sees the '='. So we notate the two possible reductions |
| to indicate that each conflicts in one rule. |

| glr.c: fix use of _Noreturn |
| In C++, [[noreturn]] must not be between "static" and the rest of the |
| function signature, it must precede it. C's _Noreturn does not seem |
| to have such a constraint, but it is therefore compatible with the C++ |
| constraint. Since we #define _Noreturn as [[noreturn]] is modern C++, |
| be sure to push the _Noreturn first. |
| |
| Unfortunately this was not caught by the test suite, because it always |
| loads config.h first, and config.h contains another definition of |
| _Noreturn that does not use [[noreturn]], and hides ours. That's |
| probably a sign we should avoid always loading config.h. |

| examples: ship them |
| Currently, the examples are extracted on the user's side. |
| Unfortunately, that requires that the user has Perl, which is |
| otherwise not needed for Bison. Let's ship the examples instead. |
| |
| The examples were handled this way so that we could depend on |
| configure flags: if --enable-gcc-warnings is passed, it is understood |
| as "I'm a maintainer", so the examples are generated with `#line`s. |
| Regular users should not see them, so they are now unconditionally |
| removed when rolling a tarball. |

| c: provide a definition of _Noreturn that works for C++ |

| __cplusplus 201402L 201703L |

| |
| So the current #definition of _Noreturn sees that 201112 <= |
| __STDC_VERSION__, i.e., that C11 is supported, so it expects _Noreturn |
| to be supported. Apparently it is not. |
| |
| This is only for C++, the test suite works for C. However, the test |

| generate the default action only for C++ |
| This commit adds restrictions to what was done in |
| 01898726e27c8cf64f8fcea7f26f8ce62f3f5cf2 [1]. |
| |
| Rici Lake [2] has shown that it's risky to disable the pre-action, at |
| least now. Also, generating the default $$ = $1 action can have bad |
| effects in some cases [3]. |
| |
| The original change [1] was prompted for C++. Let's try it there |
| only, for a start. We could restrict it further to lalr1.cc with |
| variants, but we need to see in the wild how this change behaves. And |
| it is not unreasonable to expect grammar files in C++ to behave better |
| wrt types. |

| C++: let %require "3.2" disable the generation of obsolete files |
| The files stack.hh and position.hh are deprecated. Rather than |
| devoting specify %define variables to discard them (api.position.file |
| and api.stack.file), and rather than having to use special rules when |
| api.location.file is used, let's simply decide that from %require |
| "3.2" onwards, these files will not be generated. |
| |
| The only noticeable thing here is that, in order to be able to check |
| the behavior of %require "3.2", to have this version (which is still |
| 3.1-*) to accept %require "3.2". |

| And Java 6 will be deprecated by the end of this year. So let's move |
| our requirement to Java 7. |

| generate the default semantic action |
| Currently, in C, the default semantic action is implemented by being |
| always run before running the actual user semantic action. As a |
| consequence, when the user action is run, $$ is already set as $1. |
| |
| In C++ with variants, we don't do that, since we cannot manipulate the |
| semantic value without knowing its exact type. When variants are |
| enabled, the only guarantee is that $$ is default contructed and ready |
| to the used. |
| |
| Some users still would like the default action to be run with |
| variants. Frank Heckenbach's parser in |
| C++17 (http://lists.gnu.org/archive/html/bug-bison/2018-04/msg00011.html) |
| provides this feature, but relying on std::variant's dynamic typing, |
| which we forbid in lalr1.cc. |
| |
| The simplest seems to be actually generating the default semantic |
| action (in all languages/skeletons). This makes the pre-action (that |
| sets $$ to $1) useless. But... maybe some users depend on this, in |
| spite of the comments that clearly warn againt this. So let's not |
| turn this off just yet. |
| |
| * src/reader.c (grammar_rule_check_and_complete): Rename as... |
| (grammar_rule_check_and_complete): this. |
| Install the default semantic action when applicable. |
| * examples/variant-11.yy, examples/variant.yy, tests/calc.at: |
| Exercise the default semantic action, even with variants. |

| C++: issue a better CPP guard and Doxygen file command |
| Currently we use "<dir><api.location.file>" as \file argument, and as |
| base for the CPP guard. This is not nice when <dir> is absolute, in |
| which case it is expected that the user will use api.location.include |
| to get something nicer. If defined, use that name instead. |
| |
| * data/location.cc (b4_location_path): New. |

| README: work around a nasty behavior of gettext |
| `make update-po` runs: |
| |
| package_gnu="$(PACKAGE_GNU)"; \ |
| test -n "$$package_gnu" || { \ |
| if { if (LC_ALL=C find --version) 2>/dev/null | grep GNU >/dev/null; then \ |
| LC_ALL=C find -L $(top_srcdir) -maxdepth 1 -type f \ |
| -size -10000000c -exec grep 'GNU @PACKAGE@' \ |
| /dev/null '{}' ';' 2>/dev/null; \ |
| else \ |
| LC_ALL=C grep 'GNU @PACKAGE@' $(top_srcdir)/* 2>/dev/null; \ |
| fi; \ |
| } | grep -v 'libtool:' >/dev/null; then \ |
| package_gnu=yes; \ |
| else \ |
| package_gnu=no; \ |
| fi; \ |
| }; \ |
| |
| and based on the result, put GNU or not in the following line from |
| bison.pot: |
| |
| # This file is distributed under the same license as the GNU bison package. |
| |
| It turns out that in my environment some log files had the 'GNU bison' |
| string (note the lower case), but in distcheck, these files are no |
| longer visible, so the generate bison.pot was different, and distcheck |
| failed because we try to update bison.pot, which is read only in |
| distcheck. |
| |
| The heuristics should look accept 'GNU Bison', not just 'GNU bison'. |
| But let's please it to make sure we have our 'GNU'. |
| |
| * README: Mention 'GNU bison'. |

| |
| c++: provide a means to control how location.hh is included |
| Users may want to generate the location file elsewhere, say |
| $top_srcdir/include/ast/location.hh. Yet, we should not generate |
| `#include "$top_srcdir/include/ast/location.hh"` but probably |
| something like `#include <ast/location.hh>`, or `#include |
| "ast/location.hh", or `#include <location.hh>`. It entirely depends |
| on the compiler flags (-I/-isystem) that are used. Bison cannot guess |
| what is expected, so let's give the user a means to tell how the |
| location file should be included. |
| |
| * data/location.cc (b4_location_file): New. |
| * data/glr.cc, data/lalr1.cc: Use it. |
| |
| 2018-10-06 Akim Demaille <[email protected]> |
| |
| c++: support absolute api.location.file names |
| In the case a user wants to create location.hh elsewhere, it can be |
| helpful to define api.location.file to some possibly absolute path |
| such as -Dapi.location.file='"$(top_srcdir)/include/ast/location.hh"'. |
| Currently this does not work with `-o foo/parser.cc`, as we join foo/ |
| and $(top_srcdir) together, the latter starting with slash. |
| |
| We should not try to do that in m4, manipulating file names is quite |
| complex when you through Windows file name in. Let m4 delegate this |
| to gnulib. |
| |
| * src/scan-skel.l (at_output): Accept up to two arguments. |
| * data/bison.m4 (b4_output): Adjust. |
| * tests/skeletons.at (Fatal errors but M4 continues producing output): |
| Adjust to keep the error. |
| |
| * data/location.cc, data/stack.hh: Leave the concatenation to @output. |
| * tests/output.at: Exercise api.location.file with an absolute path. |
| |
| 2018-10-06 Akim Demaille <[email protected]> |
| |
| c++: when api.location.file is defined, don't generate stack.hh |
| Make it easier to have fewer files. |
| |
| * data/stack.hh: Don't generate stack.hh when api.location.file is |
| specified. |
| * tests/calc++.at, tests/output.at: Adjust tests. |
| |
| 2018-10-06 Akim Demaille <[email protected]> |
| |
| c++: make position.hh completely useless |
| Let's put the definition of position into location.hh, there's no real |
| value in keeping them separate: they are small, and share the same |
| requirements. |
| |
| To help users transition to this new model, still generate position.hh |
| by default, but as a simple include to location.hh. |
| |
| * data/location.cc (api.position.file): Accept only 'none' as possible |
| value. |
| (position.hh): Make it a stub. |
| (location.hh): Adjust. |
| (b4_position_define): Merge into... |
| (b4_location_define): this. |
| * data/glr.cc, data/lalr1.cc, tests/input.at, tests/output.at: Adjust. |
| |
| 2018-10-06 Akim Demaille <[email protected]> |
| |
| c++: make stack.hh completely useless |
| Let's completely deprecate stack.hh. Don't provide a means to give it |
| a new name, allow only its removal. |
| |
| See https://lists.gnu.org/archive/html/bison-patches/2018-09/msg00151.html |
| and https://lists.gnu.org/archive/html/bison-patches/2018-09/msg00182.html. |
| |
| * data/stack.hh: Reduce stack.hh to a simple comment explaining how to |
| get rid of it. |
| * data/lalr1.cc: Adjust |
| * tests/input.at (%define file variables): Adjust. |
| * tests/output.at: Remove cases where stack.hh was removed. |
| |
| 2018-10-06 Akim Demaille <[email protected]> |
| |
| c++: add support for api.position.file and api.location.file |
| * data/location.cc: Sort includes. |
| (b4_position_file, b4_location_file): New. |
| When there's a file for locations but not for positions, include the |
| definition of position in the location file. |
| * data/lalr1.cc (b4_shared_declarations): Include the |
| position/location file when it exists. |
| Otherwise, define the class. |
| * data/glr.cc: Likewise. |
| * tests/input.at (%define file variables): Check them. |
| * tests/output.at (C++ output): Check various cases with |
| api.position.file and api.location.file. |
| |
| 2018-10-06 Akim Demaille <[email protected]> |
| |
| c++: provide control over the stack.hh file name |
| It was not a good idea to generate the file stack.hh. It never was. |
| But now we have to deal with backward compatibility: if we stop |
| generating it, the build system of some build system will probably |
| break. |
| |
| So offer the user a means to (i) decide what the name of the output |
| file should be, and (ii) not generate this file at all (its content |
| will be inline where the parser is defined). |
| |
| * data/lalr1.cc (b4_percent_define_check_file_complain) |
| (b4_percent_define_check_file): New. |
| * data/stack.hh: Generate the file only if api.stack.file is not |
| empty. |
| In that case, use it as file name. |
| * data/lalr1.cc: Adjust to include the right file, or to include |
| the definition of stack. |
| * tests/calc.at, tests/output.at: Exercise api.stack.file. |
| |
| 2018-10-06 Akim Demaille <[email protected]> |
| |
| tests: c++: don't fuse prefix and namespace |
| They are not the same concept. It appears that we still consider that |
| api.prefix is the default for api.namespace. We should stop that. |
| |
| * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS): |
| Separate namespace and prefix. |
| Adjust dependencies. |
| |

| Based on work by Frank Heckenbach. |
| See http://lists.gnu.org/archive/html/bug-bison/2018-04/msg00000.html |

| |
| 2018-09-22 Akim Demaille <[email protected]> |
| |
| tests: c++: use a custom string type |
| The forthcoming automove feature, to be properly checked, will require |
| that we can rely on the value of a moved-from string, which is not |
| something the C++ standard guarantees. So introduce our own wrapper. |
| |
| Suggested by Frank Heckenbach. |
| https://lists.gnu.org/archive/html/bison-patches/2018-09/msg00111.html |
| |
| * tests/c++.at (Variants): Introduce and use a new 'string' class. |
| |
| 2018-09-22 Akim Demaille <[email protected]> |
| |
| tests: prepare a test for automove |
| The 'Variants' tests are well suited to check support for move, and in |
| particular for the forthcoming automove feature. But the tests were |
| written to show the best practice in C++98, using swap: |
| |
| list "," item { std::swap ($$, $1); $$.push_back ($3); } |
| |
| This cannot work with std::move. So, make this example simpler, based |
| on regular assignment instead of swap, which is a regression for |
| C++98 (as the new traces show), but will be an improvement for modern |
| C++ with automove. |
| |
| * tests/c++.at (Variants): Stop using swap. |
| We don't generate a header file, so remove the 'require' code section. |
| Adjust expectations. |

| lalr1.cc: modern C++ no longer needs an assignment for symbols |
| Reported by Frank Heckenbach. |
| http://lists.gnu.org/archive/html/bug-bison/2018-03/msg00002.html |
| |
| Actually the assignment operator should never be needed: the C++98 |
| requirements for vector::push_back is CopyInsertable, which does not require |
| an assignment operator. However, libstdc++ shipped with GCC up to (and |
| including) 6 uses the assignment operator (which affects Clang on top of |
| libstdc++, but also ICC). So let's keep it for legacy C++. |
| |
| See https://gcc.godbolt.org/z/q0XXmC. |
| |
| * data/lalr1.cc (stack_symbol_type::operator=): Remove. |
| * data/c++.m4 (basic_symbol::operator=): Ditto. |
| * tests/c++.at (C++ Variant-based Symbols Unit Tests): Adjust. |

| |
| lalr1.cc: support move semantics |
| Modern C++ (i.e., C++11 and later) introduced "move only" types: types such |
| as std::unique_ptr<T> that can never be duplicated. They must never be |
| copied (by assignments and constructors), they must be "moved". The |
| implementation of lalr1.cc used to copy symbols (including their semantic |
| values). This commit ensures that values are only moved in modern C++, yet |
| remain compatible with C++98/C++03. |
| |
| Suggested by Frank Heckenbach, who provided a full implementation on |
| top of C++17's std::variant. |
| See http://lists.gnu.org/archive/html/bug-bison/2018-03/msg00002.html, |
| and https://lists.gnu.org/archive/html/bison-patches/2018-04/msg00002.html. |
| |
| Symbols (terminal/non terminal) are handled by several functions that used |
| to take const-refs, which resulted eventually in a copy pushed on the stack. |
| With modern C++ (C++11 and later) the callers must use std::move, and the |
| callees must take their arguments as rvalue refs (foo&&). In order to avoid |
| duplicating these functions to support both legacy C++ and modern C++, let's |
| introduce macros (YY_MOVE, YY_RVREF, etc.) that rely on copy-semantics for |
| C++98/03, and move-semantics for modern C++. |
| |
| That's easy for inner types, when the parser's functions pass arguments to |
| each other. Functions facing the user (make_NUMBER, make_STRING, etc.) |
| should support both rvalue-refs (for instance to support move-only types: |
| make_INT (std::make_unique<int> (1))), and lvalue-refs (so that we can pass |
| a variable: make_INT (my_int)). To avoid the multiplication of the |
| signatures (there is also the location), let's take the argument by value. |

| variant: fix uninitialized memory access in `variant<>` |
| Currently, in bison's C++ parser template (`lalr.cc`), the `variant<>` |
| struct's `build()` method uses placement-new in the form `new (...) T` |
| to initialize a variant type. However, for POD variant types, this |
| will leave the memory space uninitialized. If we subsequently tries |
| to `::move` into a variant object in such state, the call can trigger |
| clang's undefined behavior sanitizer due to accessing the |
| uninitialized memory. |

| examples: calc++: minor improvements |
| * doc/bison.texi (A Complete C++ Example): Prefer throw exceptions |
| from the scanner. |
| Show the invalid characters. |
| Since the scanner sends exceptions, it no longer needs to report |
| errors, so we can get rid of the driver's routine to report error, |
| do it in yyerror. |
| Use @group/@end group to improve rendering. |

| tests: disable -Wmaybe-uninitialized in some tests |
| On these tests, at -O2 and above, GCC 8 complains that yylval may be |
| uninitialized. But it seems wrong: it is initialized. Rather than |
| turning off the warning in the skeleton (hence possibility hiding |
| relevant warnings of user parsers), let's turn it off in the tests |
| only. |
| |

| c++: fix GCC8 warnings about uninitialized values |
| In 0931d14728fb4a2272399f2c927ae78e2607b4fb I removed too many |
| initializations from some ctors: some were not about base ctors, but |
| about member variables. In fact, more of them were missing to please |
| GCC 8. |
| |
| While at it, generate more natural code for C++ without variant: |
| instead of |
| |
| template <typename Base> |
| parser::basic_symbol<Base>::basic_symbol (const basic_symbol& other) |
| : Base (other) |
| , value () |
| { |
| value = other.value |
| } |
| |
| generate |
| |
| template <typename Base> |

| : Base (other) |
| , value (other.value) |
| {} |
| |
| * data/c++.m4 (basic_symbol::basic_symbol): Always initialize 'value', |
| it might be a POD without a ctor. |
| * data/lalr1.cc (stack_symbol_type::stack_symbol_type): Likewise. |
| * data/variant.hh (variant::variant): Default initialize the buffer too. |

| c++: avoid GCC 8 warnings |
| GCC 8 issues warnings whose root cause was a bit hard to find. |
| |
| calc.cc: In member function 'virtual int yy::parser::parse()': |
| calc.cc:810:18: warning: '*((void*)&<anonymous> +8)' may be used uninitialized in this function [-Wmaybe-uninitialized] |
| , location (l) |

| calc.cc:810:18: warning: '*((void*)&<anonymous> +8)' may be used uninitialized in this function [-Wmaybe-uninitialized] |
| , location (l) |
| ^ |
| |
| The problem is with locations that don't have a constructor, such as |
| Span (in calc.cc) which is POD. It is POD on purpose: so that we can |
| use that structure to test glr.cc which cannot use non POD in its |
| (C) stacks. |
| |
| * data/c++.m4 (basic_symbol): Also ensure that 'location' is |

| |
| add support for typed mid-rule actions |
| Prompted on Piotr Marcińczyk's message: |
| http://lists.gnu.org/archive/html/bug-bison/2017-06/msg00000.html. |
| See also http://lists.gnu.org/archive/html/bug-bison/2018-06/msg00001.html. |
| |
| Because their type is unknown to Bison, the values of midrule actions are |
| not treated like the others: they don't have %printer and %destructor |
| support. In addition, in C++, (Bison) variants cannot work properly. |
| |
| Typed midrule actions address these issues. Instead of: |
| |
| exp: { $<ival>$ = 1; } { $<ival>$ = 2; } { $$ = $<ival>1 + $<ival>2; } |
| |
| write: |
| |
| exp: <ival>{ $$ = 1; } <ival>{ $$ = 2; } { $$ = $1 + $2; } |
| |
| * src/scan-code.h, src/scan-code.l (code_props): Add a `type` field to |
| record the declared type of an action. |
| (code_props_rule_action_init): Add a type argument. |
| * src/parse-gram.y: Accept an optional type tag for actions. |
| * src/reader.h, src/reader.c (grammar_current_rule_action_append): Add |
| a type argument. |
| (grammar_midrule_action): When a mid-rule is typed, pass its type to |
| the defined dummy non terminal symbol. |
| |
| 2018-08-05 Akim Demaille <[email protected]> |
| |
| tests: make room for more cases |
| * tests/input.at (AT_CHECK_UNUSED_VALUES): Add an empty line |
| to allow more symbols, and adjust line numbers. |
| Use a more consistent m4 quoting scheme. |

| Avoid compiler warnings |
| At least GCC 7.3, with -O1 or -O2 (but not -O0 or -O3) generates |
| warnings with -Wnull-dereference when using yyformat: it fails to see |

| * configure.ac: Use -Wnull-dereference if supported. |
| * data/glr.c, data/lalr1.cc, data/yacc.c: Define yyformat in such |
| a way that GCC cannot not see that yyformat is defined. |

| c++: reserve 200 slots in the parser's stack |
| This is consistent with what is done with yacc.c and glr.c. Because |
| it also avoids that the stack needs to be resized very soon, it should |
| help keeping tests about destructors more reliable. |
| |
| Indeed, if the stack is created too small, very soon the C++ library |
| needs to enlarge it, which means creating a new one, copying the |
| elements from the initial one onto it, and then destroy the elements |
| of the initial stack: that would be a spurious call to a destructor. |

| bar: bar |

| reduce: don't complain about rules whose lhs is useless |
| In the following grammar, the 'exp' nonterminal is trivially useless. |
| So, of course, its rules are useless too. |
| |
| %% |
| input: '0' | exp |
| exp: exp '+' exp | exp '-' exp | '(' exp ')' |
| |
| Previously all the useless rules were reported, including those whose |
| left-hand side is the 'exp' nonterminal: |
| |
| warning: 1 nonterminal useless in grammar [-Wother] |
| warning: 4 rules useless in grammar [-Wother] |
| 2.14-16: warning: nonterminal useless in grammar: exp [-Wother] |
| input: '0' | exp |
| ^^^ |
| 2.14-16: warning: rule useless in grammar [-Wother] |
| input: '0' | exp |
| ^^^ |
| ! 3.6-16: warning: rule useless in grammar [-Wother] |
| ! exp: exp '+' exp | exp '-' exp | '(' exp ')' |
| ! ^^^^^^^^^^^ |
| ! 3.20-30: warning: rule useless in grammar [-Wother] |
| ! exp: exp '+' exp | exp '-' exp | '(' exp ')' |
| ! ^^^^^^^^^^^ |
| ! 3.34-44: warning: rule useless in grammar [-Wother] |
| ! exp: exp '+' exp | exp '-' exp | '(' exp ')' |
| ! ^^^^^^^^^^^ |
| |
| The interest of being so verbose is dubious. I suspect most of the |
| time nonterminals are not expected to be useless, so the user wants to |
| fix the nonterminal, not remove its rules. And even if the user |
| wanted to get rid of its rules, the position of these rules probably |
| does not help more that just having the name of the nonterminal. |
| |
| This commit discard these messages, marked with '!', and keep the |
| others. In particular, we still report: |
| |
| 2.14-16: warning: rule useless in grammar [-Wother] |
| input: '0' | exp |
| ^^^ |
| |
| All the useless rules (including the '!' ones) are still reported in |
| the reports (xml, text, etc.); only the diagnostics on stderr change. |

| c++: symbols can be empty, so use it |
| The previous patches ensure that symbols (symbol_type and |
| stack_symbol_type) can be empty, cleared, and their emptiness can be |
| checked. Therefore, yyempty, which codes whether yyla is empty or |
| not, is now useless. |
| |
| In C skeletons (e.g., yacc.c), the fact that the lookahead is empty is |
| coded by "yychar = YYEMPTY", which is exactly what this patch |
| restores, since yychar/yytoken corresponds to yyla.type. |

| |
| Rather that duplicating the code to destroy a symbol, or rather than |
| destroying and recreating yyla, let's provide a means to clear a |
| symbol. |

| %union: fix the support for named %union |
| Bison supports a union tag, for obscure reasons. But it does a poor |
| job at it, especially since Bison 3.0. |
| Reported by Stephen Cameron and Tobias Frost. |
| |
| It did not ensure that the name was not given several times. An easy |
| way to do this is to make the %union tag be handled as a %define |
| variable, as they cannot be defined several times. |
| |
| Since Bison 3.0, the synclines were wrongly placed, resulting in |
| invalid code. Addressing this issue, because of the way the union tag |
| was stored (as a code muscle), would have been tedious. Unless we |
| rather define the %union tag as a %percent variable, whose synclines |

| |
| symbols: properly fuse the properties of two symbol aliases |
| This completes and fixes a7280757105b2909f6a58fdd1c582de8e278319a. |
| Reported by Valentin Tolmer. |
| |
| Before it Bison used to put the properties of the symbols |
| (associativity, printer, etc.) in the 'symbol' structure. An |
| identifier-named token (FOO) and its string-named alias ("foo") |
| duplicated these properties, and symbol_check_alias_consistency() |
| checked that both had compatible properties and fused them, at the end |
| of the parsing of the grammar. |
| |
| The commit a7280757105b2909f6a58fdd1c582de8e278319a introduces a |
| sym_content structure that keeps all these properties, and ensures |
| that both aliases point to the same sym_content (instead of |
| duplicating). However, it removed symbol_check_alias_consistency, |
| which resulted in the non-fusion of *existing* properties: |
| |
| %token FOO "foo" |
| %left FOO %left "foo" |
| |
| was properly diagnosed as a redeclaration, but |
| |
| %left FOO %left "foo" |
| %token FOO "foo" |
| |
| was not, as the properties of FOO and "foo" were not checked before |
| fusion. It certainly also means that |
| |
| %left "foo" |
| %token FOO "foo" |
| |
| did not transfer properly the associativity to FOO. |
| |
| The fix is simple: reintroduce symbol_check_alias_consistency (under a |
| better name, symbol_merge_properties) and call it where appropriate. |
| |
| Also, that commit made USER_NUMBER_HAS_STRING_ALIAS useless, but left |
| it. |
| |
| * src/symtab.h (USER_NUMBER_HAS_STRING_ALIAS): Remove, unused. |
| Adjust dependencies. |
| * src/symtab.c (symbol_merge_properties): New, based on the former |
| symbol_check_alias_consistency. |

| output: do not generate source files when early errors are caught |
| Reported by Alexandre Duret-Lutz as "second problem" in: |
| http://lists.gnu.org/archive/html/bug-bison/2013-09/msg00015.html |
| |
| One problem is that some errors are caught early, before the |
| generation of output files, while others can only be detected |
| afterwards (since, for instance, skeletons can raise errors |
| themselves). |
| |
| This will be addressed in two steps: early errors do not generate |
| source files at all, while later errors will remove the files that |
| have already been generated. |
| |
| * src/scan-skel.l (yyout): Open to /dev/null when there are errors. |
| * tests/output.at (AT_CHECK_FILES): Factored out of... |
| (AT_CHECK_OUTPUT): this. |
| Fuse the "SHELLIO" argument in the "FLAGS" one. |
| Use $5 to denote the expected exit status. |

| lalr1.cc: fix the support of YYERROR with variants |
| When variant are enabled, the yylhs variable (the left-hand side of |
| the rule being reduced, i.e. $$ and @$) is explicitly destroyed when |
| YYERROR is called. This is because before running the user code, $$ |
| is initialized, so that the user can properly use it. |
| |
| However, when quitting yyparse, yylhs is also reclaimed by the C++ |
| compiler: the variable goes out of scope. |
| |
| Instead of trying to be too smart, let the compiler do its job: reduce |
| the scope of yylhs to exactly the reduction. This way, whatever the |
| type of scope exit (regular, exception, return, goto...) this variable |
| will be properly reclaimed. |
| |
| Reported by Paolo Simone Gasparello. |

| |
| * data/lalr1.cc (yyparse): Reduce the scope of yylhs. |

| YYERROR is called. This is because before running the user code, $$ |
| is initialized, so that the user can properly use it. |
| |
| However, when quitting yyparse, yylhs is also reclaimed by the C++ |
| compiler: the variable goes out of scope. |
| |
| This was not detected by the test suite because (i) the Object tracker |
| was too weak, and (ii) the problem does not show when there is error |
| recovery. |
| |

| yacc: beware of "uninitialized uses" warnings |
| Again some issues with the fact that yylval is reported by GCC as |
| possibly not initialized in some cases. Here, the case at hand is the |
| %destructor. |
| |
| I am still not convinced that it is worth going all the trouble of |
| using pragmas to disable temporarily some warnings, instead of just |
| initializing the looking symbol once for all, but that's what Paul |
| voted for, see |
| <http://lists.gnu.org/archive/html/bison-patches/2012-10/msg00050.html>. |
| |
| * data/c.m4 (b4_attribute_define): Define |
| YY_IGNORE_MAYBE_UNINITIALIZED_BEGIN, YY_IGNORE_MAYBE_UNINITIALIZED_END, |
| YY_INITIAL_VALUE here, as we will need them in the generation of the |
| destructor function, which is defined in yacc.c before yyparse, which |
| was in charge of defining these macros. |
| * data/yacc.c (b4_declare_scanner_communication_variables): Simplify: |
| trying to factor the definitions of the case pure and impure is |
| too complex. |
| Actually, it is not even clear that this macro should really exist, |
| as even the calls are complex. |
| Be careful not to issue a lone ";", as this is a statement, and C90 |
| forbids declarations after statements ; so write |
| "YY_INITIAL_VALUE(Decl;)", not "YY_INITIAL_VALUE(Decl);". |

| |
| java: add push-parser support |
| * data/lalr1.java: Capture the declarations as m4 macros to avoid |
| duplication. When push parsing, the declarations occur at the class |
| instance level rather than within the parse() function. |
| |
| Change the way that the parser state is initialized. For |
| push-parsing, the parse state declarations are moved to |
| "push_parse_initialize()", which is called on the first invocation of |
| "push_parse()". The %initial-action code is also inserted after the |
| invocation of "push_parse_initialize()". |
| |
| The body of the parse loop is modified to return values at appropriate |
| points when doing push parsing. In order to make push parsing work, |
| it is necessary to divide YYNEWSTATE into two states: YYNEWSTATE and |
| YYGETTOKEN. On the first call to push_parse(), the state is |
| YYNEWSTATE. On all later entries, the state is set to YYGETTOKEN. The |
| YYNEWSTATE switch arm falls through into YYGETTOKEN. YYGETTOKEN |
| indicates that a new token is potentially needed. Normally, with a |
| pull parser, this new token would be obtained by calling "yylex()". In |
| the push parser, the value YYMORE is returned to the caller. On the |
| next call to push_parse(), the parser will return to the YYGETTOKEN |
| state and continue operation. |
| |
| * tests/javapush.at: New test file for java push parsing. |

| drop unused options --raw, -n, -e, --include and -I |
| * --raw appears to be ignored. It was marked as obsolete in the |
| commit ec3bc39, and documented as no longer supported as of 1.29 |
| (2001-09-07). Support for %raw appears to have been dropped in |
| e9955c83 on 2002-06-11, but --raw was kept around. Maybe it's time |
| to drop it as well? |
| |
| * Commit e9955c83 dropped support for %no-parser as well, and |
| converted it to option. --no-parser was later dropped in 728c4be2 |
| on 2007-08-12, but -n was kept around, probably as an omission. All |
| three are documented as removed since 2.3b (2008-05-27). |
| |
| * -e existed for a single day in 2001. It was introduced in eeeb962b |
| on 2001-11-27. The handling was removed in c7925b99 on 2001-11-28, |
| but "e" was kept in the list of short options. Probably an |
| omission. |
| |
| * --include appears to be dead code. The option sets a variable, but |
| that variable is not used anywhere. It was added in f6bd5427 on |
| 2001-11-26 as a %-directive, with comments that it's not yet |
| implemented. It was converted to a command-line option later, but |
| doesn't seem to ever have been actually implemented. |

| Some directives cannot be used several times (e.g., a given symbol may |

| gram: correct token numbering in precedence declarations |
| In a precedence declaration, when tokens are declared with a litteral |
| character (e.g., 'a') or with a identifier (e.g., B), Bison behaved |
| differently: the litteral tokens would be numbered first, and then the |
| other ones, leading to the following grammar: |
| |
| %right A B 'c' 'd' |
| |
| being numbered as such: 'c' 'd' A B. |

| Recent discussions with Joel E. Denny |
| (http://lists.gnu.org/archive/html/bison-patches/2013-02/msg00026.html) |
| show that it is desirable to tell the difference between an option |
| that was explicitly disabled with -Wno-foo, as opposed to be left |
| unset. The current framework does not allow this. |
| |
| Instead of having a first int to store which options are enabled, and |
| another to store which are turned into errors, use an array that for |
| each warning category tells its status: disabled, unset, warning, |
| error. |

| options: no longer document warnings when diagnosing an invalid -W |
| The argmatch functions accept prefixes of the alternatives (like |
| getopt does for long options). Bison uses this to document the |
| warning categories. This is troublesome: it duplicates the --help |
| documentation, it is not gettextized, it is displayed with ugly quotes |
| (because argmatch uses it to display the list of possible answers), |
| and it prevents straighforward uses of the tables of valid warning |
| categories (for instance so that warning diagnostics end with the name |
| of the warning). |

| to be translated, nor to be described in --help. |

| variants: avoid type punning issue |
| This is based on what is recommended by both Scott Meyers, in 'Effective |
| C++', and Andrei Alexandrescu and Herb Sutter in 'C++ Coding Standards'. |
| |
| Use a static_cast on void* rather than directly use a reinterpret_cast, |
| which can have nefarious effects on objects. However, even though following |
| this guideline is good practice in general, I am not quite sure how relevant |
| it is when applied to conversions from POD to objects. Actually, it might |
| very well be the opposite: isn't this exactly what reinterpret_cast is for? |
| What we really want *is* to transmit the memory map as a series of bytes, |
| which, if I am correct, falls into the kind of "low level" hack for which |
| this cast is meant. |
| |
| In any case, this silences the warning, which will be greatly appreciated by |
| anyone using variants with a compiler supporting -fstrict-aliasing. |
| |
| * data/variant.hh (as): Here. |

| variants: remove the 'built' assertions |
| When using %define parse.assert, the variants come with additional variables |
| that are useful for development purposes. One is a Boolean indicating if the |
| variant is built (to make sure we don't read a non-built variant), and the |
| other is a string describing the stored type. There is no need to have both of |
| these, the string is enough. |

| m4: generate a basic_symbol constructor for each symbol type |
| Recently, there was a slightly vicious bug hidden in the make_ functions: |
| |
| parser::symbol_type |
| parser::make_TEXT (const ::std::string& v) |
| { |
| return symbol_type (token::TOK_TEXT, v); |
| } |
| |
| The constructor for symbol_type doesn't take an ::std::string& as |
| argument, but a constant variant. However, because there is a variant |
| constructor which takes an ::std::string&, this caused the implicit |
| construction of a built variant. Considering that the variant argument |
| for the symbol_type constructor was cv-qualified, this temporary variant |
| was never destroyed. |
| |
| As a temporary solution, the symbol was built in two stages: |
| |
| symbol_type res (token::TOK_TEXT); |
| res.value.build< ::std::string&> (v); |
| return res; |
| |
| However, the solution introduced in this patch contributes to letting |
| the symbols handle themselves, by supplying them with constructors that |
| take a non-variant value and build the symbol's own variant with that |
| value. |
| |
| * data/variant.hh (b4_symbol_constructor_define_): Use the new |
| constructors rather than building in a temporary symbol. |
| (b4_basic_symbol_constructor_declare, |
| b4_basic_symbol_constructor_define): New macros generating the |
| constructors. |

| * data/lalr1.cc: Adjust to these changes. |

| |
| c++: revamp the support for variants |
| The current approach was too adhoc: the symbols were not sufficiently |
| self-contained, in particular wrt memory management. The "new" |
| guideline is the one that should have been followed from the start: |
| let the symbols handle themslves, instead of leaving their users to |
| it. It was justified by the will to avoid gratuitious moves and |
| copies, but the current approach does not seem to be slower, yet it |
| will probably be simpler to adjust to support move semantics from |
| C++11. |
| |
| The documentation says that the %parse-param are available from the |
| %destructor. In retrospect, that was a silly design decision, which |
| we can break for variants, as its a new feature. It should be phased |
| out for non-variants too. |
| |
| * data/variant.hh: A variant never knows if it stores something or |
| not, it is up to its users to store this information. |
| Yet, in parse.assert mode, make sure the empty/filled variants |
| are properly used. |
| (b4_symbol_constructor_define_): Don't call directly the symbol |
| constructor, to save a useless temporary. |
| * data/stack.hh (push): Steal the pushed value instead of duplicating |
| it. |
| This will simplify the callers of push, who handled this "move" |
| approach themselves. |
| * data/c++.m4 (basic_symbol): Let -1, as kind, denote the fact that |
| a symbol is empty. |
| This is needed for instance when shifting the lookahead: yyla |
| is given as argument to "push", and its value is then moved on |
| the stack. But then yyla must be declared "empty" so that its |
| destructor won't be called. |
| (basic_symbol::move): New. |
| Move the responsibility of calling the destructor from yy_destroy |
| to ~basic_symbol in the case of variants. |
| * data/lalr1.cc (stack_symbol_type): Now a derived class from its |
| previous value, so that we can add a constructor from a symbol_type. |
| (by_state): State -1 means empty. |
| (yypush_): Factor, by calling one overload from the other one, and |
| using the new semantics of stack::push. |
| No longer reclaim by hand the memory from rhs symbols, since now |
| that we store objects with proper destructors, they will be reclaimed |
| automatically. |
| Conversely, be sure to delete yylhs. |
| * tests/c++.at (C++ Variant-based Symbols): New "unit" test for |
| symbols. |

| c: no longer require stdio.h when locations are enabled |
| Recent changes (in 2.7) introduced a dependency on both FILE and |
| fprintf, which are "available" only in %debug mode. This was to |
| define yy_location_print_, which is used only in %debug mode by the |
| parser, but massively used by the test suite to output the locations |
| in yyerror. |
| |
| Break this dependency: the test suite should define its own routines |
| to display the locations. Eventually Bison will provide the user with |
| a means to display locations, but not yet. |

| |
| lalr1.cc: change symbols implementation |
| A "symbol" groups together the symbol type (INT, PLUS, etc.), its |
| possible semantic value, and its optional location. The type is |
| needed to access the value, as it is stored as a variant/union. |
| |
| There are two kinds of symbols. "symbol_type" are "external symbols": |
| they have type, value and location, and are returned by yylex. |
| "stack_symbol_type" are "internal symbols", they group state number, |
| value and location, and are stored in the parser stack. The type of |
| the symbol is computed from the state number. |
| |
| The class template symbol_base_type<Exact> factors the code common to |
| stack_symbol_type and symbol_type. It uses the Curiously Recurring |
| Template pattern so that we can always (static_) downcast to the exact |
| type. symbol_base_type features value and location, and delegates the |
| handling of the type to its parameter. |
| |
| When trying to generalize the support for variant, a significant issue |
| was revealed: because stack_symbol_type and symbol_type _derive_ from |
| symbol_base_type, the type/state member is defined _after_ the value |
| and location. In C++ the order of the definition of the members |
| defines the order in which they are initialized, things go backward: |
| the value is initialized _before_ the type. This is wrong, since the |
| type is needed to access the value. |
| |
| Therefore, we need another means to factor the common code, one that |
| ensures the order of the members. |
| |
| The idea is simple: define two (base) classes that code the symbol |
| type ("by_type" codes it by its type, and "by_state" by the state |
| number). Define basic_symbol<Base> as the class template that |
| provides value and location support. Make it _derive_ from its |
| parameter, by_type or by_state. Then define stack_symbol_type and |
| symbol_type as basic_symbol<by_state>, basic_symbol<by_type>. The |
| name basic_symbol was chosen by similarity with basic_string and |
| basic_ostream. |
| |
| * data/c++.m4 (symbol_base_type<Exact>): Remove, replace by... |
| (basic_symbol<Base>): which derives from its parameter, one of... |
| (by_state, by_type): which provide means to retrieve the actual type of |
| symbol. |
| (symbol_type): Is now basic_symbol<by_type>. |
| (stack_symbol_type): Is now basic_symbol<by_state>. |
| * data/lalr1.cc: Many adjustments. |

| |
| glr.cc, yacc.c: initialize yylloc properly |
| There are several issues to address here. One is that yylloc should |
| be initialized when possible. Another is that the push parser needs |
| to update yypushed_loc when the user modified it. And if the parser |
| starts by a reduction of an empty, it uses the first location on the |
| stack, which, therefore, must also be initialized to this initial |
| location. |
| |
| This is getting complex, especially since because initializing a |
| global (impure interface) is different from initializing a local |
| variable. To simplify, the local yylloc is not initialized during its |
| definition. |

| yacc.c: initialize yylval and yylloc. |

| maint: be compilable with GCC 4.0 |
| The "shadows a global declaration" warning in GCC 4.0 was a bit |
| annoying. It does not like that a type name be used in a prototype of |
| a function (not the implementation, just the declaration): |
| |
| In file included from src/LR0.c:38: |
| src/reader.h:56: warning: declaration of 'named_ref' shadows a |
| global declaration |
| src/named-ref.h:35: warning: shadowed declaration is here |
| |
| It does not like either when a global variable name is used in a |
| prototype. Flex 2.5.37 generates this prototype: |
| |
| void gram_set_debug (int debug_flag ); |
| |
| * src/getargs.h, src/getargs.c (debug_flag): Rename as... |
| (debug): this. |

| errors: change output, and improve -y coherence |
| The prefix of warnings treated as errors is now "error: ". Also, their |

| It is now: |
| bison: warnings being treated as errors |
| input.y:1.1: error: stray ',' treated as white space [-Werror=other] |
| |
| The line "warnings being treated as errors" no longer adds any info, |
| it will be removed in a forthcoming change. |

| warnings: use the regular interface for s/r and r/r conflicts |
| The current routines used to display s/r and r/r conflicts are both |
| inconvenient from the programmer point of view (they do not use the |
| warning infrastructure) and for the user (the messages are rather |
| terse, not necessarily pleasant to read, and because they don't use |
| the same routines, they look different). |
| |
| It was due to the belief (dating back to the initial checked-in |
| version of Bison) that, at some point, POSIX Yacc mandated the format |
| for these messages. Today, the Open Group's manual page for Yacc, |
| <http://pubs.opengroup.org/onlinepubs/009695399/utilities/yacc.html>, |
| explicitly states that the format of these messages is unspecified. |
| See commit be7280480c175bed203883f524c7dcd6cf37c13d and |
| <http://lists.gnu.org/archive/html/bison-patches/2002-12/msg00027.html>. |
| |
| For a discussion on the chosen warning format, see |
| http://lists.gnu.org/archive/html/bison-patches/2012-09/msg00039.html |
| |
| In an effort to factor the handling of errors and warnings, use the |
| Bison warning routines to report these messages. |

| simplify the handling of <> and <*>'s code_props. |
| Currently they are treated in separated variables, contrary to other |
| <TYPE> code_props. This duplicates code (and messages for translators) |
| uselessly, as demonstrated by the fact that thanks to this patch, now |
| useless <*> and <> code_props are reported like the others. |

| The logic to compute the %printer or %destructor to used (i.e., a |
| code_props) is implemented twice: one, of course, in |
| symbol_code_props_get, and another time in symbol_check_defined to |
| record the fact that a code_props is used (so that we can reported |
| unused ones). Let the former use the latter. |

| api.prefix: also rename YYDEBUG. |
| The testsuite in master has shown weird errors for the "Mulitple |
| Parsers" tests: the caller of p5.parse() received some apparently |
| random value, while tracing p5.parse() showed that the function was |
| consistently returning 0. |
| |
| It happens when mixing several parser headers, some generated without |
| %debug, others with. In particular the C++ parser was generated with |
| %debug, i.e., with: |
| |
| #ifndef YYDEBUG |
| # define YYDEBUG 1 |
| #endif |
| |
| and compiled separatedly. Yet, its header was included after the one |
| of another parser, this time without %debug, i.e., with |
| |
| #ifndef YYDEBUG |
| # define YYDEBUG 0 |
| #endif |
| |
| in its header. As a result, the parser was compiled with YYDEBUG set, |
| but its header was used without. Since the layout of the objects are |
| then completely different, boom. |
| |
| Therefore, do not change the value of YYDEBUG. Rather, use it as a |
| default value for <API.PREFIX>DEBUG. |

| fix warnings for useless %printer/%destructor |
| The previous commit, which turns into a warning what used to be an |
| error: |
| |
| %printer {} foo; |
| %% |
| exp: '0'; |
| |
| has two shortcomings: the warning is way too long (foo is reported |
| to be useless later), and besides, it also turns into a warning much |
| more serious errors: |
| |
| %printer {} foo; |
| %% |
| exp: foo; |
| |

| the second. |

| the "redeclared" warning after the "redefined" one. |

| in a rule are "needed". |

| Instead, do this manually, beforehand: |
| |
| sed -i s/THRU/THROUGH/ tests/existing.at |

| maint: fix example extraction issues. |
| calc++: don't rely on Automake to compile a C++ parser. |
| |
| Basically, revert commit 609b3d8096fb0cc1fa4d908b6e1a860ced260bda, |
| Automake 1.11.3 is not safe enough for C++ parser. |
| |
| * examples/calc++/calc++-parser.hh: Remove. |
| * examples/calc++/local.mk (examples/calc++/calc++-parser.stamp): |
| New. |
| |
| examples: factor the extractions into a single step |
| |
| extexi had to be run in the extraction directory. Now, it can be |
| given the files with expected output directory. This allows to |
| use $(*_extracted) variables (before we had to list again their |
| members, but limited to their base names). In turn, this also |
| allows fusing the extraction recipes into a single one. |
| |
| Also, it is currently too hard (or requires too much duplication, |
| since Make wants all the occurrences of the files to be prefixed with |
| $(srcdir)/, which is something Automake cannot support for *_SOURCES) |
| to work in the source tree. So extract, and compile scanners and parsers |

| |
| calc++: rely on Automake. |
| Rely on $(YACC) being the bison being built, and let Automake do the |
| rest. It turned out to be much more difficult than anticipated, for |
| various reasons, including some bad behavior from Automake 1.11.2 |
| which (i) generates calc++-parser.h instead of calc++-parser.hh, and |
| (ii) leaves an #include "y.tab.h" in the generated parser instead |
| of #include "calc++-parser.h". |
| |
| The authors of Automake appear to be aware of the problem, |
| http://lists.gnu.org/archive/html/automake/2011-05/msg00008.html |
| so a simple work around will suffice for the time being. |
| |
| * examples/calc++/y.tab.h, examples/calc++/calc++-parser.hh: New. |
| To work around Automake 1.11.2 issues. |

| with bison, leave them to Automake. |

| maint: de-recurse the handling of examples |
| The directory was still using a local Makefile.am because it provides |
| "scoped" Make variables: these examples are not meant to use the same |
| CPPFLAGS etc. If we were to use the same -I set, we'd pick up |
| gnulib's stdio.h for instance, which we do not want for these simple |
| examples. |
| |
| Yet, as a result, the dependencies are less accurate, there is code |
| duplication, etc. This is especially perceptible when trying to |
| extract more examples from the documentation, as will be done in |
| forthcoming changes. |
| |
| In order to make the tuning of CPPFLAGS easier, discard the predefined |
| -I from Automake. |
| |
| * examples/calc++/Makefile.am: Rename as... |
| * examples/calc++/local.mk: this. |

| do not ignore errors like ENOSPC,EIO when writing to stdout |
| Standard output was never explicitly closed, so we could not |
| detect failure. Thus, bison would ignore the errors of writing |
| to a full file system and getting an I/O error on write, but only |
| for standard output, e.g., for --print-localedir, --print-datadir, |
| --help and some verbose output. |
| Now, "bison --print-datadir > /dev/full" reports the write failure: |
| bison: write error: No space left on device |
| Before, it would exit 0 with no diagnostic, implying success. |
| This is not an issue for "--output=-" or the other FILE-accepting |
| command-line options, because unlike most other GNU programs, |
| an output file argument of "-" is treated as the literal "./-", |
| rather than standard output. |
| * bootstrap.conf (gnulib_modules): Add closeout. |
