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.
|
|
|
|
