Bug ID: 97880
Summary: [9/10/11 Regression] ICE in emit_library_call_value_1,
at calls.c:5298
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Target Milestone: ---
With option -ftrapv at -O0, down to version r7 :
$ cat z1.c
void f ()
{
#pragma acc parallel loop tile(2, 3)
for (int i = 0; i < 8; i++)
for (long j = 0; j < 8; j++);
}
$ gcc-6 -c z1.c -fopenacc -ftrapv -O0
$
$ gcc-11-20201115 -c z1.c -fopenacc
$ gcc-11-20201115 -c z1.c -fopenacc -ftrapv -O1
$
$ gcc-11-20201115 -c z1.c -fopenacc -ftrapv -O0
during RTL pass: expand
