Bug ID: 124346
Summary: FAIL: gcc.dg/tree-ssa/copy-sign-2.c
scan-tree-dump-times optimized
Product: gcc
Version: 14.0
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 the following arm-none-eabi targets:
thumb/arch=armv7e-m+nofp/tune=cortex-m4/float-abi=soft/fpu=auto
thumb/arch=armv7e-m+nofp/tune=cortex-m7/float-abi=soft/fpu=auto
thumb/arch=armv7-m/tune=cortex-m3/float-abi=soft/fpu=auto
thumb/arch=armv7ve+neon/tune=cortex-a7/float-abi=hard/fpu=auto
thumb/arch=armv7ve+nofp/tune=cortex-a7/float-abi=soft/fpu=auto
thumb/arch=armv8.1-m.main+mve+nofp/tune=cortex-m55/float-abi=soft/fpu=auto
thumb/arch=armv8.1-m.main+mve+pacbti+nofp/tune=cortex-m85/float-abi=soft/fpu=auto
thumb/arch=armv8-m.main+dsp+nofp/tune=cortex-m33/float-abi=soft/fpu=auto
Depending on arm-none-eabi target, different number of patterns match.
The test passes on x86_64-pc-linux-gnu.
I think these failures started with GCC14.
