[LLVMdev] Generating movq2dq using IRBuilder
Hi all, How do I generate the movq2dq SSE2 instruction using the IRBuilder? There is no zext from 64-bit to 128-bit (corresponding to MMX to XMM register transfer) as far as I can tell. So I've tried inserting an i64 into a v2i64, which generates valid code but rather a number of stores and loads on the stack instead of a single movq2dq. Looking though the code, I found a pattern for
