Hi!
I'd like to compile my kernel with the Cflag "-mfpmath=sse,387", but instead of using both instruction sets GCC compiles the kernel with sse arithmetics only:
| Quote: | | warning: 387 instruction set disabled, using SSE arithmetics |
As processor family I selected "Athlon/Duron/K7" in the kernel. My CPU is an Athlon XP 2500+.
What do I have to do now to get get both, the sse- and the 387-Mathunit, to work?
I'd be happy if you could help me with this problem. 
P.S.: Sorry for my bad English but it's not my mother tongue... |

It's usually best to leave the kernel alone cflag wise, but if you really want to mess with it here is a link on how to compile the kernel with different CFLAGS.
