------- Comment #45 from rob1weld at aol dot com 2009-01-31 22:13 ------- Here is another attempt using "gcc version 4.4.0 20090128 (experimental) [trunk revision 143729]" to compile "gcc version 4.4.0 20090131 (experimental) [trunk revision 143817]".
I have an Athlon X2 running OpenSolaris in 32-bit boot mode on VirtualBox. To attempt to make as much difference between the compilers as possible I first set a few Environment Variables prior to ./configuring the build: export set CC='gcc -ffloat-store -msse3 -mssse3 -m3dnow -msse4.1 -mfpmath=sse,387' export set CPPFLAGS=-fexceptions export set CXX='g++ -ffloat-store -msse3 -mssse3 -m3dnow -msse4.1 -mfpmath=sse,387' Here is the result of the "../gcc_trunk/contrib/compare_tests" output: # ../gcc_trunk/contrib/compare_tests ../gcc_build/gcc/testsuite/gcc/gcc.log.BACKUP.PRE_INSTALL ../gcc_build/gcc/testsuite/gcc/gcc.log.BACKUP.POST_INSTALL # (Nothing Printed) This particular time there is no difference on that one log file.
