Hi all, I was wondering how to use variations of intrinsic functions that take a memory operand. Take for example the SSE4.1 pmovsxbd instruction. One variant takes two XMM registers, while another has a 32-bit memory location as source operand. The latter is quite interesting if you know you're reading from memory anyway, and if it's not 16-byte aligned. It looks like LLVM's Intrinsic::x86_sse41_pmovsxbd expects a...
