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).
