--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
MSVC (in 64bit 19.30.30423.0) does:
vucomisd xmm0, xmm1
jp SHORT $LN3@g
jne SHORT $LN3@g
mov eax, 1
ret 0
$LN3@g:
xor eax, eax
ret 0
MSVC (32bit, 19.30.30423.0) does:
vmovsd xmm0, QWORD PTR _x$[esp-4]
vucomisd xmm0, QWORD PTR _y$[esp-4]
mov edx, 1
lahf
xor ecx, ecx
test ah, 68 ; 00000044H
cmovnp ecx, edx
mov eax, ecx
; Line 5
ret 0
I don't know why there is a difference as both are the same version.
Confirmed.
