ipa-cp: Add dumping of overall_size after cloning
When experimenting with IPA-CP parameters, especially when looking
into exchange2_r, it has been very useful to know what the value of
overall_size is at different stages of the decision process. This
patch therefore adds it to the generated dumps.
gcc/ChangeLog:
2020-09-07 Martin Jambor <mjambor@suse.cz>
* ipa-cp.c (estimate_local_effects): Add overeall_size to dumped
string.
(decide_about_value): Add dumping new overall_size.
