Bug ID: 89834
Summary: New test case gcc.dg/vect/pr81740-2.c introduced in
r269938 fails on power 7
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: ---
This only fails on power 7 BE; it works find on power 8 BE.
On power 7 the compilation options include "-mvsx -mno-allow-movmisalign" while
on power 8 that is replaced with "-mpower8-vector". So perhaps the expected
vectorization only occurs on power 8 and later?
