Hi Zdenek,
I'm a big fan of your "store motion" rewrite.
However, I'm now getting a testsuite regression on i686-pc-linux-gnu
for f90-intrinsic-bit.f when compiled with:
g77 -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions ...
Fortunately, your patch was easy to diagnose as the source of the
failure, adding "-fno-gcse-sm" fixes the regression :>
I see you have an alias-set follow-up pending review so I can't
tell if the issue has already been fixed. Anyway I thought you'd
like to know.
Roger
