SubjectWhy does C3 CPU downgrade in kernel 2.4.20?
Date
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
