Hi,
I have been searching the web about compiling FreeBSD kernel with optimized compiler flags and for Intel SSE2, but coulnd't find any relevant information; seems like make script uses -mno-sse2. I would also like to use a newer compiler, gcc45, if possible. I would like to compile this kernel only for my computer. That aside, I am not sure whether SSE2 kernel outperforms a non-sse2 kernel dramatically and how much CPU time does kernel use, compared to user apps. But I think my wish still is relevant.
I would be very happy to know whether what I wish is possible. Is it possible to alter compiler flags for kernel compilation, at least parts of kernel compilation? Does it lead to weird things, if not crashes?
Regards,
Jason
