Bug ID: 70681 Summary: [6 Regression] FAIL: gcc.dg/ira-shrinkwrap-prep-2.c gcc.dg/pr10474.c on arm and powerpc Product: gcc Version: 6.0 Status: UNCONFIRMED Keywords: missed-optimization Severity: normal Priority: P3 Component: rtl-optimization Assignee: unassigned at gcc dot gnu.org Reporter: ktkachov at gcc dot gnu.org Target Milestone: --- Target: arm, powerpc As reported at: https://gcc.gnu.org/ml/gcc-patches/2016-03/msg01640.html and https://gcc.gnu.org/ml/gcc-patches/2016-04/msg00094.html The tests: gcc.dg/ira-shrinkwrap-prep-2.c scan-rtl-dump pro_and_epilogue "Performing shrink-wrapping" gcc.dg/pr10474.c scan-rtl-dump pro_and_epilogue "Performing shrink-wrapping" Have started failing on arm and powerpc after a regalloc change. On arm at least the resulting codegen doesn't look worse (https://gcc.gnu.org/ml/gcc-patches/2016-04/msg00223.html) but arguably shrink-wrapping could be improved (https://gcc.gnu.org/ml/gcc-patches/2016-04/msg00265.html) This is a report to track work on shrinkwrapping or adjustment of the testscases
