[PATCH] D15197: [WebAssembly] Support constant offsets on loads and stores

[Dan Gohman via llvm-commits]

sunfish added a comment.

> We'll also want to optimize things so that LLVM knows to generate positive offsets instead of negative ones (post-increment as much as possible). Do you know if there's a knob for that? It's just an optimization so maybe just mention it in the list of work to do in the README?


The main hook we can use is WebAssemblyTargetLowering::isLegalAddressingMode, and there's a TODO for it in WebAssemblyInstrMemory.md.
