[Bug target/82941] Missing vzeroupper with -march=skylake-avx512 -O2
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82941 --- Comment #4 from speryt at gcc dot gnu.org --- Author: speryt Date: Mon Dec 4 11:40:44 2017 New Revision: 255379 URL: https://gcc.gnu.org/viewcvs?rev=255379&root=gcc&view=rev Log: Fix PR82941 and PR82942 by adding proper vzeroupper generation on SKX. Add X86_TUNE_EMIT_VZEROUPPER to indicate if vzeroupper instruction should be inserted before a transfer of control flow out of the function. It is turned on by default unless we are tuning for KNL. Users can always use -mzeroupper or -mno-zeroupper to override X86_TUNE_EMIT_VZEROUPPER. 2017-12-04 Sebastian Peryt H.J.
