[LLVMdev] Lowering to MMX
...t
revision 115243 removes the MMX lowering rules, but I don't know if the
rest of LLVM 3.0 would still support them if I simply reverted them.
Please note that I'm not an LLVM expert and I'd prefer not having to
maintain local changes. Would there be any objection to having an
'EnableMMX' flag (false by default)?
3) I believe all MMX instructions are available as intrinsics now? That
would allow me to replace all straight LLVM operations with intrinsics.
I'm just wondering what the downsides of that would be? I assume I won't
get any benefits from instruction combini...

Ok, thanks for confirming that this would be too complex.
