The `bound_nodes.rs` file has been removed and its contents have been
moved to `src/ast/nodes.rs`. This consolidates all AST node definitions
into a single module, improving organization and maintainability.
The `compiler` modules now import these definitions from
`crate::ast::nodes` instead of `crate::ast::compiler::bound_nodes`.
Introduce `collect_pattern_addrs` to gather all bound addresses from a
destructuring pattern. This enables the optimizer to remove unused
destructuring definitions, similar to how simple unused definitions are
handled. Added integration tests to verify this behavior and other
optimizer robustness scenarios.
The Binder and related types have been refactored to use the new
`NodeKind` enum instead of the previous `BoundKind`. This commit updates
all references to use the new structure, ensuring consistency across the
compiler's AST representation.
Key changes include:
- Replacing `BoundKind` with `NodeKind` in the Binder's `bind` and
`visit` methods.
- Updating pattern matching and field access to reflect the new enum
variants (e.g., `NodeKind::Def` instead of `BoundKind::Define`).
- Adjusting identifier bindings to use the new `IdentifierBinding` enum.
- Reflecting changes in `DefBinding`, `AssignBinding`, and
`LambdaBinding` structures.
- Ensuring all newly created nodes use `NodeKind` and the appropriate
metadata.
This commit refactors the AST substitution logic to correctly handle
nested expansions and improve the inlining of lambda expressions.
The changes include:
- Extracting the core value from potentially expanded AST nodes before
checking their kind.
- Ensuring that lambda expressions with empty upvalues are correctly
substituted.
- Adding support for inlining global get expressions as AST
substitutions.
- Improving the `UsageInfo` collection to correctly track assigned
values.
Introduce generic `CompilerPhase` trait to unify different stages of the
bound AST. Rename `LocalSlot` to `VirtualId` and introduce `StackOffset`
for clearer distinction between compile-time and run-time addressing.
Update type aliases and implementations to reflect these changes.
This commit replaces the `UntypedNode` enum with the more accurately
named `SyntaxNode`. This change is primarily for clarity and better
reflects the role of these nodes as representing the structure of the
source code prior to semantic analysis.
The corresponding enum `UntypedKind` has also been renamed to
`SyntaxKind` to maintain consistency.
No functional changes are introduced by this refactoring; it is purely a
renaming and organizational update.
The `Analyzer` is now responsible for determining the purity of `Define`
bindings. Previously, this responsibility was left to the caller.
Added a new example `design-flaw.myc` to test this change.
Updated `soa_series.myc` due to the purity change.
The Binder and its helper functions have been updated to accept and
propagate a `Diagnostics` struct. This allows for better error reporting
during the binding phase, enabling the compiler to continue processing
even after encountering errors and collect all issues before halting.
The `BoundKind::Error` node and `StaticType::Error` are introduced as
"poison" nodes/types. These nodes indicate that an error occurred during
compilation, preventing further valid processing of that specific AST
fragment but allowing the compiler to continue with other parts of the
code.
The `Parser` has also been updated to return a `Diagnostics` struct,
enabling it to report errors during the initial parsing stage while
still attempting to build a partial AST. This adheres to the same error
recovery strategy.
Introduces type specialization for reactive pipeline nodes and their
data buffers. This eliminates the overhead of generic `Value` enums and
`SharedValueSeries` when dealing with known scalar or record types.
The architecture shifts buffer instantiation from the VM to the runtime
(RTL), leveraging type information from the AST. A new `out_type` field
is added to `BoundKind::Pipe` to store the static type of the pipeline's
output, determined by the type checker.
This enables the creation of specialized `RingBuffer<T>` and
`SharedRecordSeries` (for Struct-of-Arrays layout) when the output type
is known, significantly improving memory usage and processing speed for
time-series data, especially in financial analysis.
Introduces a new `Pipe` node to the Abstract Syntax Tree (AST).
This node represents a functional composition pattern, allowing
for chaining of operations.
The changes include:
- Defining the `Pipe` variant in `BoundKind` and `UntypedKind`.
- Implementing parsing logic for the `pipe` keyword.
- Adding handling for the `Pipe` node in various compiler passes
(analyzer, binder, captures, dumper, macros, optimizer, TCO,
type checker).
- Including a placeholder implementation for `Pipe` execution in the
VM.
- Updating integration tests to use the new `pipe` syntax.
This commit refactors the internal representation of `BoundKind::Record`
to store a `RecordLayout` and a `Vec` of values, rather than a `Vec` of
key-value pairs. This change simplifies the representation and improves
efficiency by decoupling the record's structure from its specific values
during compilation and analysis.
The `RecordLayout` now defines the structure of the record, and the
values are stored in a separate vector, ordered according to the layout.
This allows for better optimization and type checking, as the record's
shape is explicitly defined and immutable once created.
Introduces a new `RecordLayout` system for efficient and type-safe
record handling.
Key changes:
- `RecordLayout` struct with `O(1)` field lookup using FMap
optimization.
- Field accessors (`.name`) are now first-class callable values.
- Parser recognizes dot-prefixed identifiers as field accessors.
- Binder and TypeChecker handle field accessors.
- Optimizer transforms field accessor calls into specialized `GetField`
nodes.
- VM executes `GetField` efficiently by directly accessing record
values.
- Adds a new `records.myc` example showcasing record features.
- Improves comparison logic for records to use pointer equality for
layout.
Removes unused `flatten_tuple` function from optimizer utilities. The
functionality was moved to the `Folder` struct, making it more
contextually appropriate. This change streamlines the utility module and
improves code organization.
Introduces the `Inliner` struct to encapsulate logic related to value
and function inlining. This improves code organization and readability
within the optimizer engine.
Key changes include:
- Moving `is_inlinable_value` to the `Inliner` struct.
- Extracting beta-reduction preparation logic into
`Inliner::prepare_beta_reduction`.
- Moving parameter slot collection to
`Inliner::collect_parameter_slots`.
- Introducing `flatten_tuple` to a new `utils` module, used by both
`Folder` and `Inliner`.
