ipa-cp: New debug counters for IPA-CP
Martin Liška has been asking me to add debug counters to the IPA-CP pass so
that testcase reductions are easier. The pass already has one for the bit
value propagation, so this patch adds one for value_range propagation
and one for the actual constant propagation.
gcc/ChangeLog:
2020-10-30 Martin Jambor <mjambor@suse.cz>
* dbgcnt.def (ipa_cp_values): New counter.
(ipa_cp_vr): Likewise.
* ipa-cp.c (decide_about_value): Check and bump ipa_cp_values debug
counter.
(decide_whether_version_node): Likewise.
(ipcp_store_vr_results):Check and bump ipa_cp_vr debug counter.
