# "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.
