| libcxxabi |
| ========= |
| |
| This library implements the Code Sourcery C++ ABI, as documented here: |
| |
| http://www.codesourcery.com/public/cxx-abi/abi.html |
| |
| It is intended to sit below an STL implementation, and provide features required by the compiler for implementation of the C++ language. |
| |
| Current Status |
| -------------- |
| |
| At present, the library implements the following parts of the ABI specification: |
| |
| - RTTI classes and support for the dynamic_cast<> operator. |
| - Exception handling. |
| - Thread-safe initializers. |
| |
| Exception handling requires the assistance of a stack-unwinding library |
| implementing the low-level parts of the ABI. Either libgcc_s or libunwind |
| should work for this purpose. |
| |
| The library depends on various libc features, but does not depend on any C++ |
| features not implemented purely in the compiler or in the library itself. |
| |
| Supported Platforms |
| ------------------- |
| |
| This code was initially developed on FreeBSD/x86, and has also been tested on FreeBSD/x86-64. It should work on other platforms that use the Code Sourcery ABI, for example Itanium, however this is untested. |
| |
| Currently, this library has no support for ARM EABI (or any other ARM ABI). |
