In fact -mno-sse3 and -mno-mmx are passed in to make sure that these options dont not get feed through. Here is a piece from a kernel build with these options still in my make.conf cc -c -O2 -frename-registers -pipe -fno-strict-aliasing -march=nocona -std=c99 -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -fformat-extensions -nostdinc -I. -I/usr/src/sys -I/usr/src/sys/contrib/altq -D_KERNEL -DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -fno-omit-frame-pointer -mcmodel=kernel -mno-red-zone -mfpmath=387 -mno-sse -mno-sse2 -mno-sse3 -mno-mmx -mno-3dnow -msoft-float -fno-asynchronous-unwind-tables -ffreestanding -fstack-protector -Werror /usr/src/sys/dev/pccbb/pccbb_isa.c However, the world will include these options is there are in the make.conf Paul
