Very non-scientific benchmark: Did compile latest gmic-1.3.4.0 on a 2xL5540 system (plenty of RAM) with make -j8 and compile flags: -O3 --param max-inline-insns-auto=200 -ffast-math -funroll-loops -ftree-vectorize Times (in seconds, user, elapsed): 4.3.5: 1263u, 377e w/ -fno-tree-pre: 755u, 202e 4.4.4: 1022u, 311e w/ -fno-tree-pre: 996u, 284e 4.5.0: 2325u, 615e w/ -fno-tree-pre: 1974u, 543e Note that this is in contrast to earlier observations that 4.4/4.5 did do much better than 4.3. Don't know whether that's caused by changed gmic code or whether we have regressed in 4.5. Let me know if you want me to pick one file that takes particularly long to compile and investigate further. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36439
