Summary: [8 regression] gcc.dg/pr21643.c and
gcc.dg/tree-ssa/phi-opt-11.c fail starting with
r249450
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
These fail on powerpc64 both LE and BE.
gcc.dg/tree-ssa/ipa-split-5.c also started failing with this revision but since
has been fixed.
The test cases may just need to be adjusted for the differences introduced by
this revision.
