# SHA1 block procedure for s390x.
|
|
|
|
# April 2007.
|
|
#
|
|
# Performance is >30% better than gcc 3.3 generated code. But the real
|
|
# twist is that SHA1 hardware support is detected and utilized. In
|
|
# which case performance can reach further >4.5x for larger chunks.
|
|
|
|
# January 2009.
|
|
#
|
|
# Optimize Xupdate for amount of memory references and reschedule
|
|
# instructions to favour dual-issue z10 pipeline. On z10 hardware is
|
|
# "only" ~2.3x faster than software.
|
|
|
|
# November 2010.
|
|
#
|
|
# Adapt for -m31 build. If kernel supports what's called "highgprs"
|
|
# feature on Linux [see /proc/cpuinfo], it's possible to use 64-bit
|
|
# instructions and achieve "64-bit" performance even in 31-bit legacy
|
|
# application context. The feature is not specific to any particular
|
|
# processor, as long as it's "z-CPU". Latter implies that the code
|
|
# remains z/Architecture specific. On z990 it was measured to perform
|
|
# 23% better than code generated by gcc 4.3.
