Note that the compile time at, say, -O1 for 4.3 vs. 4.4 is also a huge difference for the test case (4.4 much slower, in part due to the expensive heuristic). Therefore, IMHO, this is still a 4.4 regression too. We should not be running such expensive algorithms just for inline heuristics. We need to figure out a cheaper heuristic. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38584
