Rather than using paths from the root instruction to the instruction we are matching against or checking if it is constant or whatever, use temporary variables. When we successfully match an instruction's opcode, we simultaneously define these temporaries for the instruction's operands. This is similar to how open-coding these matches in Rust would use `match` expressions with pattern matching to bind the operands to variables at the same time. This saves about 1.8% of instructions retired when Peepmatic is enabled.
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
