cfgcleanup.c (try_crossjump_to_edge): Use combine_with_count to merge probabilities.
* cfgcleanup.c (try_crossjump_to_edge): Use combine_with_count
to merge probabilities.
* predict.c (probably_never_executed): Also mark as cold functions
with global 0 profile and guessed local profile.
* profile-count.c (profile_probability::combine_with_count): New
member function.
* profile-count.h (profile_probability::operator*,
profile_probability::operator*=, profile_probability::operator/,
profile_probability::operator/=): Reduce precision to adjusted
and set value to guessed on contradictory divisions.
(profile_probability::combine_with_freq): Remove.
(profile_probability::combine_wiht_count): Declare.
(profile_count::force_nonzero):: Set to adjusted.
(profile_count::probability_in):: Set quality to adjusted.
* tree-ssa-tail-merge.c (replace_block_by): Use
combine_with_count.
