I'm curious if the original 172.mgrid regression is believed to still exist in
GCC 4.8.1. I notice that ipa-cp.c has Martin's special case for RESTRICT
pointers, yet building 172.mgrid for AArch64 seems to result in an inlined
version of resid_() which does not get vectorized. Using -fno-inline-functions
(or alternatively --param inline-min-speedup=17) produces code which runs
significantly faster. It's remotely possible that I have some local edits
which are causing the regression, but I suspect that the issue is still present
for the mgrid case and wanted to verify that before attempting another
work-around.
