GNU Mach and FPU support (exceptions handling mode)

[Evgeniy Ivanov]

Hi list,

I'm implementing FPU/MMX/SSE support in Minix 3 and not sure what mode for exceptions handling should be used: MS-DOS compatible or native.
Why does GNU Mach use MS-DOS compatible mode (I didn't find any place, where CR0.NE is set)? Intel manual highly recommends using native mode, also you can't use MS-DOS compatible mode in multiprocessors PCs (probably in multicore too).

Thanks in advance for all answers.
