Bug ID: 92464 Summary: [10 regression] r 278033 breaks gcc.dg/vect/costmodel/ppc/costmodel-vect-76b.c Product: gcc Version: 10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: testsuite Assignee: unassigned at gcc dot gnu.org Reporter: seurer at gcc dot gnu.org Target Milestone: --- This happens on power 7 but things work fine on power 8 and 9. Does the test case just need to be adjusted when run on power 7?
