Hi Uros,
This patch is to correct previous patch,
PREFETCHW should be both in march=broadwell and march=Silvermont,
but I move PREFETCHW from march=broadwell to march=silvermont in previous
patch, sorry for that.
Bootstrap is ok, and no regressions for i386/x86-64 testsuite.
OK for master?
[PATCH] Put PREFETCHW back to march=broadwell
PREFETCHW should be both in march=broadwell and march=silvermont.
I move PREFETCHW from march=broadwell to march=silvermont in previous
patch.
gcc/ChangeLog:
* config/i386/i386.h: Add PREFETCHW to march=broadwell.
* doc/invoke.texi: Put PREFETCHW back to relation arch.
