Another testcase:
[hjl@gnu-tools-1 gcc]$ cat /tmp/x.c
enum gomp_schedule_type
{
GFS_GUIDED,
GFS_AUTO
};
struct gomp_work_share
{
enum gomp_schedule_type sched;
};
struct gomp_team_state
{
struct gomp_work_share *work_share;
};
struct gomp_thread
{
void *data;
struct gomp_team_state ts;
};
extern __thread struct gomp_thread gomp_tls_data;
_Bool
foo (void)
{
return gomp_tls_data.ts.work_share->sched == GFS_GUIDED;
}
[hjl@gnu-tools-1 gcc]$ ./xgcc -B./ -mx32 -S -O2 /tmp/x.c
/tmp/x.c: In function ‘foo’:
/tmp/x.c:24:1: internal compiler error: in check_rtl, at lra.c:2014
}
