When I compile nbench using gcc compiled from snapshot ftp://gcc.gnu.org/pub/gcc/snapshots/4.8-20130224/ there is different result from nbench compiled using gcc from GIT using revision 196245 http://gcc.gnu.org/ml/gcc/2013-02/msg00273.html nbench compiled using gcc snapshot is fast nbench compiled using gcc revision is slow file nbench1.c.164t.optimized is same with both gcc builds, but executable has different size despite of using same CFLAGS nbench compiled using gcc revision has 1366219 bytes nbench compiled using gcc snapshot has 1205879 bytes
