Bug ID: 87078
Summary: [9 regression] gcc.dg/vect/slp-37.c begins failing
with r263772
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
Does the test case needs updating with this revision? Hmmm, the test case WAS
updated it looks like.
Some further testing shows this happens only on power 7 and earlier. Power 8
and 9 work fine.
testgcc: 263772 had unexpected test case failures
testgcc: results of test run:
# of expected passes 4
# of unexpected failures 4
