Hi all, I rebuilt the 2.4.20 kernel with C3 CPU and found it been downgraded to i486. And I check the file, linux/arch/i386/Makefile, in both of 2.4.19 and 2.4.20 kernels. In 2.4.19, the CFLAGS adds "-march=i586". But in 2.4.20, the CFLAGS adds "-march=i486 -malign-functions=0 -malign-jumps=0 -malign-loops=0". Why do this? Could anybody explain this to me? BTW, if I substitute"i586" for "i486" and remove other parameters in that file under 2.4.20, is there any affection during/after rebuilding kernel? Any help is appreciated. Best Regards, Joseph
