Implement a couple of more simplifications. This lets us codegen:
...
int test2(int * P, int* Q, int A, int B) {
return P+A == P;
}
into:
test2:
movl 4(%esp), %eax
movl 12(%esp), %eax
shll $2, %eax
cmpl $0, %eax
sete %al
movzbl %al, %eax
ret
instead of:
test2:
movl 4(%esp), %eax
movl 12(%esp), %ecx
leal (%eax,%ecx,4), %ecx
cmpl %eax, %ecx
sete %al
movzbl %al, %eax
ret
ICC is producing worse code:
test2:
movl 4(%esp), %eax #8.5
movl 12(%esp), %edx #8.5
lea (%edx,%edx), %ecx #9.9
addl %ecx, %ecx #9.9
addl %eax, %ecx #9.9
cmpl %eax, %ecx #9.16
movl $0, %eax #9.16
sete %al #9.16
ret #9.16
as is GCC (looks like our old code):
test2:
movl 4(%esp), %edx
movl 12(%esp), %eax
leal (%edx,%eax,4), %ecx
cmpl %edx, %ecx
sete %al
