Subject: [PATCH] Remove AVX512_VP2INTERSECT from PTA_SAPPHIRERAPIDS
Date: Wed, 12 Oct 2022 10:59:45 +0800 [thread overview]
Message-ID: <20221012025945.578-1-lili.cui@intel.com> (raw)
Hi Hontao,
This patch is to remove AVX512_VP2INTERSECT from PTA_SAPPHIRERAPIDS.
The new intel ISE removes AVX512_VP2INTERSECT from SAPPHIRERAPIDS, AVX512_VP2INTERSECT is only supportted in Tigerlake.
Hi Uros,
This patch is to remove AVX512_VP2INTERSECT from PTA_SAPPHIRERAPIDS.
The new intel ISE removes AVX512_VP2INTERSECT from SAPPHIRERAPIDS, AVX512_VP2INTERSECT is only supportted in Tigerlake.
Bootstrap is ok, and no regressions for i386/x86-64 testsuite.
OK for master?
gcc/ChangeLog:
* config/i386/driver-i386.cc (host_detect_local_cpu):
Move sapphirerapids out of AVX512_VP2INTERSECT.
* config/i386/i386.h: Remove AVX512_VP2INTERSECT from PTA_SAPPHIRERAPIDS
* doc/invoke.texi: Remove AVX512_VP2INTERSECT from SAPPHIRERAPIDS
