| 10 # SHA1 block procedure for PA-RISC. | |

| 12 # June 2009. | |
| 13 # | |
| 14 # On PA-7100LC performance is >30% better than gcc 3.2 generated code | |
| 15 # for aligned input and >50% better for unaligned. Compared to vendor | |
| 16 # compiler on PA-8600 it's almost 60% faster in 64-bit build and just | |
| 17 # few percent faster in 32-bit one (this for aligned input, data for | |
| 18 # unaligned input is not available). | |
