Looking at [the `fcmp` documentation](https://docs.rs/cranelift-codegen/0.80.0/cranelift_codegen/ir/trait.InstBuilder.html#method.fcmp)--generated from Cranelift's instruction definitions, the charts explaining the logic for the various conditions is unreadable. Since rendering those charts as plain text is problematic, this change wraps them as code sections for a consistent layout.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
