Hello, the patch sequence in this thread adds a call_summary class, which is analogous to function_summary we already have but which gathers information about call graph edges, rather than nodes.
The first patch implements the class itself, the second modifies ipa-prop.[ch] and ipa-cp.c to use it instead of a vector indexed by edge->uid and the third patch is a semi-related cleanup I spotted along the way. I have LTO-bootstrapped and tested the patches on x86_64-linux and successfully LTO-built Mozilla Firefox with it. I'll be grateful for any comments, otherwise I'll queue the series for the next stage1. Thanks, Martin Martin Jambor (3): call_summary to keep info about cgraph_edges Use call_summary in ipa-prop and ipa-cp Remove ipa_update_after_lto_read gcc/ipa-cp.c | 4 - gcc/ipa-inline-analysis.c | 2 +- gcc/ipa-inline.c | 3 - gcc/ipa-profile.c | 2 +- gcc/ipa-prop.c | 82 ++++-------------- gcc/ipa-prop.h | 60 +++++++++---- gcc/symbol-summary.h | 214 +++++++++++++++++++++++++++++++++++++++++++++- 7 files changed, 273 insertions(+), 94 deletions(-) -- 2.11.1
