McCoy (Jan 02 2022 at 00:00): McCoy (Jan 02 2022 at 00:00):I was checking out the IR reference: https://github.com/bytecodealliance/wasmtime/blob/main/cranelift/docs/ir.md it seems like any type information is not displayed when printing the IR. I checked out the InstBuilder https://docs.rs/cranelift-codegen/latest/cranelift_codegen/ir/trait.InstBuilder.html and also noticed (similarly) that most instruction creation doesn't require specifying types. How should I understand types in cranelift?
