r243066 - in /branches/ARM/sve-branch/gcc: conf...


Author: rsandifo
Date: Wed Nov 30 19:08:36 2016
New Revision: 243066

URL: https://gcc.gnu.org/viewcvs?rev=243066&root=gcc&view=rev
Log:
Add an empty_mask_is_expensive hook

[Branch only patch -- not intended for trunk in its current state]

This patch adds a hook to control whether we avoid executing masked
(predicated) stores when the mask is all false.  We don't want to do
that by default for SVE.
