I want to know whether gcc dumps the branch predictions it made based on profiles or heuristics? I know gcc outputs the .gcda files when -fprofile-arcs is used. But I am interested on how gcc uses them and what predictions does it make -- View this message in context: http://gcc.1065356.n5.nabble.com/Dumping-branch-predictions-made-by-gcc-tp1085407.html Sent from the gcc - Help mailing list archive at Nabble.com.
