-# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL

-# Performance is 2x of gcc 3.4.6 on z10. Coding "secret" is to
-# "cluster" Address Generation Interlocks, so that one pipeline stall
-# resolves several dependencies.
-
-# 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
-# 50% better than code generated by gcc 4.3.
