<div>
<pre>int f(int a, int b)
{
if ((a < 4 && b == 'r') || (a == 1 && (b == 'h' || b == 'i')) || (a == 2))
a = b;
}
Compiling this results in this assembly output:
f(int, int):
cmp edi, 1
It should be possible to remove the `cmp edi, 1` as far as I know. I guess this
isn't really by itself considering the behaviour is undefined anyway but this
behaviour itself seems rather weird.</pre>
