addc, turn it into add.
This allows us to compile:
long long test(long long A, unsigned B) {
return (A + ((long long)B << 32)) & 123;
}
into:
_test:
movl $123, %eax
andl 4(%esp), %eax
xorl %edx, %edx
ret
instead of:
_test:
xorl %edx, %edx
movl %edx, %eax
addl 4(%esp), %eax ;; add of zero
andl $123, %eax
ret
