* profile-count.c (safe_scale_64bit): Fix GCC4.x path. (profile_probability): Set max_probability to (uint32_t) 1 << (n_bits - 2) and update accessors to avoid overlfows in temporaries. * profile-count.c (profile_probability::differs_from_p): Do not rely on max_probaiblity == 10000 * gcc.dg/predict-13.c: Update template for probaility change. * gcc.dg/predict-8.c: Likewise.
