            Bug ID: 119234
           Summary: openblas miscompiled with -mcpu=power8
           Product: gcc
           Version: 14.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rguenth at gcc dot gnu.org
  Target Milestone: ---

https://github.com/OpenMathLib/OpenBLAS/pull/5125 reports that the power8 CPU
variant of OpenBLAS fails to pass its testsuite after
https://github.com/OpenMathLib/OpenBLAS/commit/ba47c7f4f301aad100ed166de338b86e01da8465#diff-b28db202c2e9d48c23975c369812e78c427c66f7681d382202226690b4d8e2b6
which looks like an innocous change introducing vector intrinsics to
vectorize straight-line code.

-mcpu=power9 and -mcpu=power10 work fine.
