The patch works for me for the described case, but does not for PGO, which should do the same based on real numbers:įor (int i = 0 i : > proper testing and send to gcc-patches. > With this patch GCC optimizes original example. > in emit_case_decision_tree to emit expected comparison prior to decision > How about this? I added edge attribute for builtin_expect and later used it (In reply to Yuri Gribov from comment #8) Instead the test for 333/$0x14d should have been moved to the front. Take this code:Ĭurrent mainline (and also prior versions, I tested 4.8.2) produce with -O3 code like this:Ģ2:Ė6 0f 1f 44 00 00 nopw 0x0(%rax,%rax,1)ģ2:Ė6 0f 1f 44 00 00 nopw 0x0(%rax,%rax,1) When used in switch, _builtin_expect should reorder the comparisons appropriately. ![]()
