Summary: OpenMP ICE with atomics on __float128 in 32-bit only
i686 cc1
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, openmp
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: jakub@gcc.gnu.org
ReportedBy: jakub@gcc.gnu.org
extern void abort (void);
int
main ()
{
__float128 f = 0.0;
int i;
#pragma omp parallel for reduction(+:f)
for (i = 0; i < 128; i++)
f++;
if (f != 128.0Q)
abort ();
return 0;
}
ICEs with -fopenmp in 32-bit i686-linux cc1 (while works fine with x86_64-linux
cc1 with -fopenmp -m32).
