I'm not even sure what WMMX is, so I have no idea how to use it. For
sure you would at least need to write some assembly. As for the current
inline assembly parts (for the ARMv4 arch), you would need to convert
them to VC++. It shouldn't be too hard, just push/load the registers at
the beginning and then save/pop at the end. It's just the small macros
(in fixed_arm4.h) that you won't be able to use because with VC++ inline
assembly, the overhead will be larger than the benefit.
