enum { E0 = 0, E1 = 1, E2 = 2 } e;
int
foo (void)
{
return __builtin_popcount ((int) e);
}
int
bar (int x)
{
return __builtin_popcount (x);
}
In foo this is expanded into a call to __builtin_popcount, rather than
__popcountsi2 (or popcount instruction), at least on i?86/x86_64/ppc/ppc64.
In 4.1 this used to work correctly.
