fitzgen opened PR #9085 from fitzgen:pulley-memory-access-big-offset to bytecodealliance:main:

I had trimmed these instructions from the original upstreaming of the Pulley interpreter because I had mistakenly believed that they were unused. Turns out they are needed for Cranelift's Pulley backend to allow for lowering certain address modes to a single instruction. The alternative, lowering the address modes to a sequence of instructions, would be a bit annoying and these instructions seem generally useful.

Would it perhaps make sense to add a generlized helper load32_u_offset which takes offset: usize which no-offset/offset8/offset64 all call? (and would presumably get inlined and not actually matter at runtime)

Mayyybe. Right now some of the offset-to-isize conversions are .into() and some are as isize which is a small hiccup, but probably inconsequential. All said, I think I'd prefer to just leave it as-is for now and see what the future brings.
