Details:
For enabling fast math instruction, support for FPU MMX/XMM state is needed.
As Roland said,
``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).''
