From: Giuliano Belinassi <giulianob@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc/devel/autopar_devel] Add -fdump-profile-report. Date: Sat, 22 Aug 2020 23:29:51 +0000 (GMT) [thread overview] Message-ID: <20200822232951.7441E387087B@sourceware.org> (raw) https://gcc.gnu.org/g:797da60343b0382ed055da8880b87d36d02e5c27 commit 797da60343b0382ed055da8880b87d36d02e5c27 Author: Martin Liska <mliska@suse.cz> Date: Thu Jul 9 11:58:11 2020 +0200 Add -fdump-profile-report. When using -fprofile-report, -fdump-profile-report can be used to print the report to a foo.c.000i.profile-report file instead of stderr. I see it handy for comparison purpose. gcc/ChangeLog: * dumpfile.c [profile-report]: Add new profile dump. * dumpfile.h (enum tree_dump_index): Ad TDI_profile_report. * passes.c (pass_manager::dump_profile_report): Change stderr to dump_file.
