A simplified test:
[hjl@gnu-cfl-2 pr103268]$ cat x.c
static int si;
long
test_types (long n)
{
unsigned int u2 = __atomic_fetch_xor (&si, 0, 5);
return u2;
}
[hjl@gnu-cfl-2 pr103268]$ make
/export/build/gnu/tools-build/gcc-gitlab-debug/build-x86_64-linux/gcc/xgcc
-B/export/build/gnu/tools-build/gcc-gitlab-debug/build-x86_64-linux/gcc/ -O2 -S
x.c
during GIMPLE pass: fab
x.c: In function ‘test_types’:
x.c:3:1: internal compiler error: in optimize_atomic_bit_test_and, at
