[LLVMdev] Memcpy expansion: InstCombine vs SelectionDAG
Hi all,
We currently have code in InstCombine that tries to expand memcpy / memmove intrinsics that are copying something that fits in a single register to a load and store in the IR. We then have other code in SelectionDAG that expands small memcpy intrinsics to sequences of loads and stores. The InstCombine one is useful, as it exposes more optimisation opportunities, but unfortunately it is
