Introduces a new optimizer pass that can "crack" closures, allowing for
more aggressive specialization. It also enables inlining of upvalues
that point to immutable global variables. This removes overhead for
higher-order functions and currying when arguments are statically
resolvable.
Introduce a `--trace` flag to the AST tool that enables the
TracingObserver.
This allows users to see the detailed execution steps of their scripts.
Also, refactor the main and AST tool to better handle tracing and
performance
statistics.
Introduces `LambdaCollector` to gather lambda functions and populate the
function registry. This enables the `Specializer` to work with
user-defined functions.
The `Environment` struct is updated to manage the `function_registry`
and `monomorph_cache`, which are essential for the specialization
process.
The `link` method in `Environment` now incorporates lambda collection
and node specialization before applying TCO optimization. This ensures
that lambdas are properly processed and specialized for potential
performance gains.
The `Specializer`'s `new` constructor has been modified to accept and
initialize the `MonoCache` through an `Rc<RefCell<MonoCache>>`. This
allows the cache to be shared across different specialized functions.
Also includes minor refactoring and type adjustments in `specializer.rs`
for better clarity and consistency.
This commit introduces a new `tester` module to the `ast` crate,
enabling functional tests and performance benchmarks for MYC scripts.
Functional tests are executed by reading `.myc` files from the
`examples` directory, parsing expected output comments, and comparing
them against the actual script execution results.
Benchmarking involves measuring the execution time of scripts,
calculating median durations, and comparing them against stored
baselines. The commit also adds support for updating these baselines.
The `ast.rs` CLI and the `main.rs` GUI application have been updated to
expose these new testing and benchmarking features. The `Cargo.toml` and
`Cargo.lock` files have been updated to include the `regex` dependency
required for parsing benchmark comments.
The project now uses the `clap` crate for handling command-line
arguments, replacing the previous manual parsing approach. This includes
adding `clap` as a dependency and creating a `Cli` struct to define the
command-line interface. The `main` function has been updated to parse
these arguments and handle file input or direct script evaluation.
