# Eternal question is what's wrong with compiler generated code? The
# trick is that it's possible to reduce the number of shifts required
# to perform rotations by maintaining copy of 32-bit value in upper
# bits of 64-bit register. Just follow mux2 and shrp instructions...
# Performance under big-endian OS such as HP-UX is 179MBps*1GHz, which
# is >50% better than HP C and >2x better than gcc. As of this moment
# performance under little-endian OS such as Linux and Windows will be
# a bit lower, because data has to be picked in reverse byte-order.
# It's possible to resolve this issue by implementing third function,
# sha1_block_asm_data_order_aligned, which would temporarily flip
# BE field in User Mask register...
