gnumach doesn't support newer fpu state for mmx/xmm et al.
would need new thread state flavor for "fpx" or whatever we call it.
cf linux asm/user.h user_i387_struct vs user_fxsr_struct
former is what mach can handle. need to handle latter in ctx sw + user
thread state flavor, then enable cpu support bits (cr4 bit i think).
Roland thanks.
Can one of the Savannah project members please create a task for this?
I tried to but apparently only members can create new tasks, etc?
Also, does anyone happen to know why i386_fp_save and i386_fp_regs are
split out? In Linux's user.h they are in 1 struct: user_i387_struct.
Thanks as always!
