            Bug ID: 91461
           Summary: Don't turn on X86_TUNE_SSE_TYPELESS_STORES for
                    AVX/AVX512
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hjl.tools at gmail dot com
                CC: crazylht at gmail dot com, skpgkp2 at gmail dot com
  Target Milestone: ---
            Target: i386

We have

X86_TUNE_SSE_TYPELESS_STORES: Always movaps/movups for 128bit stores

since movaps/movups one byte shorter than movdaq/movdqu.  But it isn't
the case for AVX/AVX512.  There is no need to do it for AVX/AVX512.
