[WIP] Experimental Slim `AstNode` API #59992

rbuckton · 2024-09-17T19:20:07Z

This adds an experimental "slim" API for AST nodes that is intended to be highly monomorphic while maintaining the existing public API. This will also allow for gradual adoption of the new slim API internally.

This is a very early proof-of-concept designed to test the ramifications of this change and whether they will be beneficial to compiler performance long-term. The general principle of the change is that compiler internals will no longer depend on the highly polymorphic Node type, and instead depend on a slimmer AstNode class with a fixed layout that is roughly the following:

class AstNode<N extends Node> {
  // lazy-initialized extra fields for a node (id, original, emitNode, transformFlags, 
  // modifierFlagsCache, etc.)
  private _extra: AstNodeExtraFields | undefined;
  
  // Constructor used to produce a `Node` facade for the public API
  private _nodeConstructor: (new (ast: AstNode<N>) => N) | undefined;
  
  // Lazy-initialized `Node` facade for the public API
  private _node: N | undefined;

  kind: N["kind"];
  data: N["data"];
  parent: AstNode | undefined;
  flags: NodeFlags;
  pos: number;
  end: number;

  constructor(kind: N["kind"], data: N["data"], nodeConstructor: new (ast: AstNode<N>) => N) {
    ...
  }

  // lazy-initializes the `Node` facade for this AstNode
  get node() { ... }

  // lazy-initialized properties of an AstNode
  get id() { ... }
  set id(value) { ... }
  get original() { ... }
  set original(value) { ... }
  get emitNode() { ... }
  set emitNode(value) { ... }
  get transformFlags() { ... }
  set transformFlags(value) { ... }
}

This "slim" node is designed to be small and allow for monomorphic access to the most common shared properties of our AST nodes. In place of the existing Node type, the public API would surface a facade based on something like this definition of Node:

class Node<K extends SyntaxKind, T extends AstData> {
  /** @internal */ readonly ast: AstNode<Node<K, T>>;

  constructor(ast: AstNode<Node<K, T>>) {
    this.ast = ast;
  }

  /** @internal */ get data(): T { return this.ast.data; }

  get kind(): K { return this.ast.kind; }
  get pos() { return this.ast.pos; }
  get end() { return this.ast.end; }
  get flags() { return this.ast.flags; }
  get parent() { return this.ast.parent; }
  get id() { return this.ast.id; }
  // etc.
}

Node-specific fields will live in objects held by the data property, such as this class that describes a BinaryExpression:

class AstBinaryExpressionData extends AstData {
  left!: AstNode<Expression>;
  operatorToken!: AstNode<BinaryOperatorToken>;
  right!: AstNode<Expression>;
  // etc.
}

While the BinaryExpression we provide today would be replaced by a facade:

class BinaryExpression extends Node<SyntaxKind.BinaryExpression, AstBinaryExpressionData> {
  declare _expressionBrand: any;
  declare _declarationBrand: any;
  declare _jsdocContainerBrand: any;

  /** @internal */ declare readonly ast: AstBinaryExpression;

  get left() { return this.ast.data.left?.node; }
  set left(value) { this.ast.data.left = value?.ast; }
  get operatorToken() { return this.ast.data.operatorToken?.node; }
  set operatorToken(value) { this.ast.data.operatorToken = value?.ast; }
  get right() { return this.ast.data.right?.node; }
  set right(value) { this.ast.data.right = value?.ast; }
  // etc.
}

type AstBinaryExpression = AstNode<BinaryExpression>;

Work on this PR is expected to progress in stages. Until work has progressed far enough along, we expect performance numbers to be much worse before they get better due to the overhead from the compiler internals relying on the facade vs the slim node.

There will hopefully be some additional benefits to this change if it shows promise:

Removes use of objectAllocator for node constructors
Moves all language service Node extensions to the compiler (e.g., no more NodeObject)
Common structure of AstNode could allow for more efficient encodings of pos/end/flags/etc.
Potentially easy to swap out internally with shared structs in the future.

TODO

Initial "slim" AstNode implementation
Minimal AstNode version of NodeFactory and ParenthesizerRules
Redirect NodeFactory and ParenthesizerRules to leverage AstNode-versions
Migrate parser.ts to use AstNode
Migrate binder.ts to use AstNode
Migrate checker.ts to use AstNode
Migrate transformers to use AstNode
Migrate emitter.ts to use AstNode
Migrate language service to use AstNode

Being less aggressive with respect to optional chaining in the facade accessors didn't seem to have much of an impact. I suspect the biggest impact is that the per-node constructors are resulting in far more megamorphic ICs. I might be able to address this by duplicating all of the accessors on Node on each of the individual subtypes so that the accessors are monomorphic. I'll push up an experimental commit to test that this afternoon, but I think the major perf improvements will come from migrating the internals to use the monomorphic slim AST.
