Bug ID: 115872
Summary: error: missing definition with -g & -O3
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
This C code:
long set_work_pending_p;
_Bool set_work_pending() {
_Bool __trans_tmp_1;
long mask = 1, old = __atomic_fetch_or(&set_work_pending_p, mask, 0);
__trans_tmp_1 = old & mask;
return !__trans_tmp_1;
}
void __queue_work() {
_Bool ret = set_work_pending();
if (ret)
__queue_work();
}
does this with recent gcc:
cvise $ ~/gcc/results/bin/gcc -c -g -O3 bug1040.c
bug1040.c: In function ‘__queue_work’:
bug1040.c:8:6: error: missing definition
8 | void __queue_work() {
| ^~~~~~~~~~~~
for SSA_NAME: _6 in statement:
# DEBUG ret => (_Bool) _6
during GIMPLE pass: fab
bug1040.c:8:6: internal compiler error: verify_ssa failed
The bug first seems to appear sometime before g:66d6b1861ec57ba2,
dated 20240611.
