Bug ID: 113437
Summary: gcc.dg/tree-ssa/pr95906.c fails on arm since
g:6686e16fda4
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
CC: liuhongt at gcc dot gnu.org
Target Milestone: ---
We have detected the following regression since gcc-14-7124-g6686e16fda4:
FAIL: gcc.dg/tree-ssa/pr95906.c scan-tree-dump-times forwprop3 "max_expr" 1
on arm targets where Neon or MVE is not enabled by default.
In these cases VECTOR_MODE_P (V16QImode) returns false, thus the optimization
introduced by this commit.
I'm not sure how/if we want to add an effective-target to handle this case.
