Hi,
so what goes wrong with the testcase is the fact that after recursive
inliing we have large loop nest and consequently invalid profile since
every loop is predicted to iterate quite a lot. Rebuild_frequences
should take care of the problem, but it doesn't since there is:
if (freq_max < 1
> __attribute__((noipa)) void
> bar (void)
> {
> __builtin_exit (0);
> }
>
> __attribute__((noipa)) void
> foo (void)
> {
> for (int i = 0; i < 1000; ++i)
> for (int j = 0; j < 1000; ++j)
> for (int k = 0; k < 1000; ++k)
> for (int l = 0; l < 1000; ++l)
> for (int m = 0; m < 1000; ++m)
