--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The *.optimized dump then has:
struct FRAME.global_event FRAME.1;
static integer(kind=4) options.0[7] = {68, 8191, 0, 1, 1, 0, 31};
integer(kind=4) _8;
<bb 2> [local count: 1073741825]:
_gfortran_set_args (argc_2(D), argv_3(D));
_gfortran_set_options (7, &options.0[0]);
_8 = FRAME.1.x;
if (_8 != 0)
goto <bb 3>; [0.04%]
else
goto <bb 4>; [99.96%]
<bb 3> [local count: 429497]:
_gfortran_error_stop_numeric (1, 0);
<bb 4> [local count: 1073312327]:
return 0;
where it is more clear that it actually reads an uninitialized variable and
decides based on it if it should stop 1 or not. Everything else is optimized
away.
