So then shouldn't this bug be about:
unsigned long long
foo (unsigned long long ns)
{
return ns % 1000000000L;
}
unsigned long long
bar (unsigned long long ns)
{
return ns - (ns / 1000000000L) * 1000000000L;
}
not compiling the same code at -Os? On x86_64 with -O2 it actually produces
identical code with the subtraction, supposedly that's faster. Guess even
(ns / 1000000000L) * 1000000000L should be folded into
ns - (ns % 1000000000L).
