Subject: [PATCH] i386: Treat Granite Rapids/Granite Rapids-D/Diamond Rapids
similar as Sapphire Rapids in x86-tune.def
Since GNR, GNR-D, DMR are both P-core based, we should treat them
just like SPR for now.
gcc/ChangeLog:
* config/i386/x86-tune.def
(X86_TUNE_DEST_FALSE_DEP_FOR_GLC): Add GNR, GNR-D, DMR.
(X86_TUNE_AVOID_256FMA_CHAINS): Ditto.
(X86_TUNE_AVX512_MOVE_BY_PIECES): Ditto.
(X86_TUNE_AVX512_STORE_BY_PIECES): Ditto.
