Bug ID: 124166
Summary: gcc.dg/vect/vect-cond-[134].c FAIL
scan-tree-dump-times vect "OUTER LOOP VECTORIZED" 1
Product: gcc
Version: 15.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
All of these test cases have the following statement:
/* { dg-final { scan-tree-dump-times "OUTER LOOP VECTORIZED" 1 "vect" { xfail {
vect_no_align && { ! vect_hw_misalign } } } } } */
As these test cases only fail for Cortex-M0, I assume that this has something
to do with -march=armv6s-m and/or thumb1 and that it's not correctly handled in
the vect_* checks.
