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