--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
GCC 3.4 managed
f:
pushl %ebp
movl %esp, %ebp
cmpl $1, 8(%ebp)
popl %ebp
sbbl %eax, %eax
notl %eax
ret
(32bit code here)
given we expand this from
_1 = x_3(D) != 0;
_2 = (int) _1;
_4 = -_2;
it might be we do not have conditional negation "patterns"?
