Bug ID: 124345
Summary: FAIL: gcc.dg/tree-ssa/abs-4.c scan-tree-dump-times
optimized
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
This test appears to fail for all arm-none-eabi targets.
I'm unable to find any GCC version that produces the expected number of pattern
matches in the optimized file for arm-none-eabi.
The test passes on x86_64-pc-linux-gnu.
