[LLVMdev] Using intrinsics with memory operands
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
