From 91153e0af9a457a0085bb796613a81404480d5af Mon Sep 17 00:00:00 2001 From: Martin Jambor Date: Fri, 2 Oct 2020 18:41:35 +0200 Subject: [PATCH] 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 * ipa-cp.c (estimate_local_effects): Add overeall_size to dumped string. (decide_about_value): Add dumping new overall_size. --- gcc/ipa-cp.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/gcc/ipa-cp.c b/gcc/ipa-cp.c index f6320c787de..12acf24c553 100644 --- a/gcc/ipa-cp.c +++ b/gcc/ipa-cp.c @@ -3517,7 +3517,8 @@ estimate_local_effects (struct cgraph_node *node) if (dump_file) fprintf (dump_file, " Decided to specialize for all " - "known contexts, growth deemed beneficial.\n"); + "known contexts, growth (to %li) deemed " + "beneficial.\n", overall_size); } else if (dump_file && (dump_flags & TDF_DETAILS)) fprintf (dump_file, " Not cloning for all contexts because " @@ -5506,6 +5507,9 @@ decide_about_value (struct cgraph_node *node, int index, HOST_WIDE_INT offset, val->spec_node = create_specialized_node (node, known_csts, known_contexts, aggvals, callers); overall_size += val->local_size_cost; + if (dump_file && (dump_flags & TDF_DETAILS)) + fprintf (dump_file, " overall size reached %li\n", + overall_size); /* TODO: If for some lattice there is only one other known value left, make a special node for it too. */ -- 2.30.2
