It is unrelated to any other programs. I just execute this command:
> gcc-4.7 -I. -I/usr/local/Cellar/freetype/2.4.10/include/freetype2 \
> -Ilibdvdread4 -march=native -S command.c

then open command.s, I can find these strange instructions.

Man page of my gcc 4.7 tells me that native is only supported on
Linux, and I've provided a link for source of man page of gcc which
says that as well. Isn't it enough?
