commit 16245986fb9bfe396113fc7dfd1929f69a9e748e
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Fri Aug 20 06:42:24 2021 -0700
x86-64: Optimize load of all bits set into ZMM register [BZ #28252]
Optimize loads of all bits set into ZMM register in AVX512 SVML codes
by replacing
vpbroadcastq .L_2il0floatpacket.16(%rip), %zmmX
and
vmovups .L_2il0floatpacket.13(%rip), %zmmX
with
vpternlogd $0xff, %zmmX, %zmmX, %zmmX
This fixes BZ #28252.
