  10 # SHA256 performance improvement over compiler generated code varies
  11 # from 40% for Sun C [32-bit build] to 70% for gcc [3.3, 64-bit
  12 # build]. Just like in SHA1 module I aim to ensure scalability on
  13 # UltraSPARC T1 by packing X[16] to 8 64-bit registers.
  14
  15 # SHA512 on pre-T1 UltraSPARC.
  16 #
  17 # Performance is >75% better than 64-bit code generated by Sun C and
  18 # over 2x than 32-bit code. X[16] resides on stack, but access to it
  19 # is scheduled for L2 latency and staged through 32 least significant
  20 # bits of %l0-%l7. The latter is done to achieve 32-/64-bit ABI
  21 # duality. Nevetheless it's ~40% faster than SHA256, which is pretty
  22 # good [optimal coefficient is 50%].
  23 #
  24 # SHA512 on UltraSPARC T1.
  25 #
  26 # It's not any faster than 64-bit code generated by Sun C 5.8. This is
  27 # because 64-bit code generator has the advantage of using 64-bit
  28 # loads(*) to access X[16], which I consciously traded for 32-/64-bit
  29 # ABI duality [as per above]. But it surpasses 32-bit Sun C generated
  30 # code by 60%, not to mention that it doesn't suffer from severe decay
  31 # when running 4 times physical cores threads and that it leaves gcc
  32 # [3.4] behind by over 4x factor! If compared to SHA256, single thread
  33 # performance is only 10% better, but overall throughput for maximum
  34 # amount of threads for given CPU exceeds corresponding one of SHA256
  35 # by 30% [again, optimal coefficient is 50%].
  36 #
  37 # (*)   Unlike pre-T1 UltraSPARC loads on T1 are executed strictly
  38 #       in-order, i.e. load instruction has to complete prior next
  39 #       instruction in given thread is executed, even if the latter is
  40 #       not dependent on load result! This means that on T1 two 32-bit
  41 #       loads are always slower than one 64-bit load. Once again this
  42 #       is unlike pre-T1 UltraSPARC, where, if scheduled appropriately,
  43 #       2x32-bit loads can be as fast as 1x64-bit ones.
