Hmm, devirt-2 is also the case we do not inline because function is called
once.
With main renamed to main2 I get at -O3
int main2() ()
{
<bb 2>:
printf ("%d\n", 1);
printf ("+1: %d\n", 2);
printf ("%d\n", 2);
printf ("+1: %d\n", 3);
return 0;
}
from GCC-4.7 as well as from the mainline.
Similarly for devirt-3.C. I will check why this is not matched by the heavy
heuristic I invented for PR55478, but otherwise I think it is non-bug.
Also in devirt-3 we no longer unroll the loop of 3 printf calls, that is IMO
fine.
We should add the updated testcases (with renamed main) to the testsuite IMO.
