Further reduced testcase:
int
xtermEnvEncoding(void)
{
static int result;
if (result == 0)
result = 2;
return result;
}
Basicially the issue is that the if is emitted as cmp 0, result instead of what
it was before as
set regtmp, result
cmp regtmp, 0
so GCSE/PRE does not see the load.
And yes this is load PRE which means this is most likely be fixed for 4.2 on
the tree level.
