Bug ID: 71293 Summary: [7 regression] test case gcc.dg/plugin/must-tail-call-2.c fails starting with r236514 Product: gcc Version: 7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: seurer at linux dot vnet.ibm.com Target Milestone: --- From looking at the test results for other platforms this appears to be specific to power. It fails on both BE and LE.
