* cranelift: Remove of/nof overflow flags from icmp Neither Wasmtime nor cg-clif use these flags under any circumstances. From discussion on #3060 I see it's long been unclear what purpose these flags served. Fixes #3060, fixes #4406, and fixes #4875... by deleting all the code that could have been buggy. This changes the cranelift-fuzzgen input format by removing some IntCC options, so I've gone ahead and enabled I128 icmp tests at the same time. Since only the of/nof cases were failing before, I expect these to work. * Restore trapif tests It's still useful to validate that iadd_ifcout's iflags result can be forwarded correctly to trapif, and for that purpose it doesn't really matter what condition code is checked.
This crate provides an interpreter for Cranelift IR. It is still a work in progress, as many instructions are unimplemented and various implementation gaps exist. Use at your own risk.
