Bill, could you or someone else with access to Power benchmarking try this patch out on some benchmarks

that you usually use? The new pass in this patch is on by default and can be turned off by -fno-store-merging
if needed.  Jakub indicated that his last attempt at this work caused regressions on powerpc so I'd like to
see if this patch is okay in that regard.

Hi Kyrill,

Thanks for the heads-up!  I will have someone on my team look at this as soon as possible.


I tried the patch on SPEC2006 on powerpc64le and the results were neutral, no noticeable improvements or degradations.


Thanks for checking.
Much appreciated
Kyrill
