| # SHA256/512 block procedure for PA-RISC. | |
| # June 2009. | |
| # | |
| # SHA256 performance is >75% better than gcc 3.2 generated code on | |
| # PA-7100LC. Compared to code generated by vendor compiler this | |
| # implementation is almost 70% faster in 64-bit build, but delivers | |
| # virtually same performance in 32-bit build on PA-8600. | |
| # | |
| # SHA512 performance is >2.9x better than gcc 3.2 generated code on | |
| # PA-7100LC, PA-RISC 1.1 processor. Then implementation detects if the | |
| # code is executed on PA-RISC 2.0 processor and switches to 64-bit | |
| # code path delivering adequate peformance even in "blended" 32-bit | |
| # build. Though 64-bit code is not any faster than code generated by | |
| # vendor compiler on PA-8600... | |
