19# June 2009.
20#
21# On PA-7100LC performance is >30% better than gcc 3.2 generated code
22# for aligned input and >50% better for unaligned. Compared to vendor
23# compiler on PA-8600 it's almost 60% faster in 64-bit build and just
24# few percent faster in 32-bit one (this for aligned input, data for
25# unaligned input is not available).
