This lets us avoid the cost of `cranelift_codegen::ir::Opcode` to `peepmatic_runtime::Operator` conversion overhead, and paves the way for allowing Peepmatic to support non-clif optimizations (e.g. vcode optimizations). Rather than defining our own `peepmatic::Operator` type like we used to, now the whole `peepmatic` crate is effectively generic over a `TOperator` type parameter. For the Cranelift integration, we use `cranelift_codegen::ir::Opcode` as the concrete type for our `TOperator` type parameter. For testing, we also define a `TestOperator` type, so that we can test Peepmatic code without building all of Cranelift, and we can keep them somewhat isolated from each other. The methods that `peepmatic::Operator` had are now translated into trait bounds on the `TOperator` type. These traits need to be shared between all of `peepmatic`, `peepmatic-runtime`, and `cranelift-codegen`'s Peepmatic integration. Therefore, these new traits live in a new crate: `peepmatic-traits`. This crate acts as a header file of sorts for shared trait/type/macro definitions. Additionally, the `peepmatic-runtime` crate no longer depends on the `peepmatic-macro` procedural macro crate, which should lead to faster build times for Cranelift when it is using pre-built peephole optimizers.

//! Shared traits, types, and macros for Peepmatic.
|
|
//!
|
|
//! This crate is used both at build time when constructing peephole optimizers
|
|
//! (i.e. in the `peepmatic` crate), and at run time when using pre-built
|
|
//! peephole optimizers (i.e. in the `peepmatic-runtime` crate and in
|
|
//! Cranelift's Peepmatic integration at `cranelift/codegen/src/peepmatic.rs`).
|
|
//!
|
|
//! This crate is similar to a header file: it should generally only contain
|
|
//! trait/type/macro definitions, not any code.
