> Nice! Thanks for writing this :D Do you know what happens when you actually try to compile some code with `-mrelaxed-simd`? I'm concerned that it will throw an error because the "relaxed-simd" target feature has not yet been defined in the backend (specifically in WebAssembly.td and in WebAssemblySubtarget.{h,cpp}).

It output "'+relaxed-simd' is not a recognized feature for this target (ignoring feature)" but didn't fail compilation. I fixed it by adding to WebAssembly.td and WebAssemblySubtarget.h, thanks!
