Relationship between MachineMemOperand and X86II::getMemoryOperandNo
Thanks for the details!
How should we think of the case where an instruction has memory operands
(in the sense that X86II::getMemoryOperandNo >=0), but doesn't have
MachineMemOperands?
I'm seeing an example in the case of __builtin_prefetch (lowered via
SelectionDAG::getMemIntrinsicNode, which produces a MachineMemOperand) vs
__builtin_ia32_gatherpfdpd, lowered through getPrefetchNode

[LLVMdev] Add support for ldr pseudo instruction in ARM integrated assembler
...,
with minor variations. For example, check out these from x264 (a video
encoder, and one of the most highly optimized programs in existence):
