From: "marxin at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug gcov-profile/99105] profile streaming scales poorly to projects with many source files Date: Mon, 15 Feb 2021 13:58:57 +0000 [thread overview] Message-ID: <bug-99105-4-E7wXhXNek8@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-99105-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99105 --- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> --- Thank you for the bug report. It's really something we should improve for the next GCC release. A small improvement can be achieved by the removal of libgcov I/O buffering: https://gcc.gnu.org/git/?p=gcc.git;a=patch;h=5a17015c096012b9e43a8dd45768a8d5fb3a3aee But the key thing is likely the ability to omit profile modifications (read/modify/write) for parts of a binary that are not trained.
