--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
GCC can do this for switch expansion right now,
enum class E { a, b, c, d, e, f, g, h, i, j };
bool check_mask(E v) {
switch (v) {
case E::b: case E::e: case E::f: case E::j: return true;
default: return false;
}
}
xorl %eax, %eax
cmpl $9, %edi
ja .L1
movl $1, %eax
movl %edi, %ecx
salq %cl, %rax
testl $562, %eax
setne %al
.L1:
ret
