            Bug ID: 112611
           Summary: LoongArch: Test cases lsx-vshuf.c and lasx-xvshuf_b.c
                    fails on LA664
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: xry111 at gcc dot gnu.org
  Target Milestone: ---

Some test cases in these two files depend on some undocumented behavior of
LA464, now they fail with LA664.

I guess we should just remove the problematic test cases.
