--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note funky_bandpass in GCC 13+ no longer produces an imull but rather does
neg/and instead:
movl %edx, %eax
cmpl %edx, %edi
setle %dl
cmpl %esi, %eax
setl %al
andl %eax, %edx
cmpb $1, %dl
movzbl %dl, %edx
sbbq %rax, %rax
negq %rdx
andq %rax, %rcx
andq %rdx, %r8
leaq (%rcx,%r8), %rax
