Bug ID: 125264
Summary: FAIL: gcc.dg/torture/bitint-95.c -O0 (test for
excess errors)
Product: gcc
Version: 16.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
In r16-8828-ge33201aa19c9e4 and r17-67-gdcaa624319dc58, the
gcc.dg/torture/bitint-95.c was added.
For arm-none-eabi, the new test fails for Cortex-M0:
For other Cortex-M, there does not appear to be any call to any
__atomic_fetch_* functions, hence they PASS.
Testing torture/bitint-95.c, -O0
