Interesting. You compiled with `-O2`, I compiled without optimization.
When I compile it with `-O2`, I now get `0`.

I've uploaded a gist with the disassembly generated with

```
clang -mllvm --x86-asm-syntax=intel -S test.c -o ./test-no-optimize.S
```
and
```
clang -O2 -mllvm --x86-asm-syntax=intel -S test.c -o ./test-optimize-O2.S
```

Can you do the same?
