            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: crazylht at gmail dot com
  Target Milestone: ---

error: inlining failed in call to 'always_inline' '__m512i
_mm512_permutexvar_epi8(__m512i, __m512i)': target specific option mismatch

}

gcc11/gcc12 -O2 -march=sapphirerapids -S

in i386.h

constexpr wide_int_bitmask PTA_SAPPHIRERAPIDS = PTA_COOPERLAKE | PTA_MOVDIRI

It should base on PTA_ICELAKE_SERVER instead on PTA_COOPERLAKE
