* 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 a straightforward way to create a
Cranelift IR function and fill it with
instructions translated from another language. It contains an SSA construction
module that provides convenient methods for translating non-SSA variables into
SSA Cranelift IR values via use_var and def_var calls.
