[LLVMdev] Implementing MMX and SSE shifts

Hi all,

 

Recently some great work has been done to implement vector shifts as
described in the language reference, and I'd like to contribute by
attempting to match these operations on x86 to MMX and SSE instructions
whenever possible.

 

I'm experienced in writing MMX and SSE assembly but I'm unfamiliar with how
LLVM performs instruction selection. So every bit of information to get me
started would be very much appreciated.

 

Thanks,

 

Nicolas
