Shrink `ast.Symbol` from 96 to 80 bytes by mds-ant · Pull Request #4786 · microsoft/typescript-go

mds-ant · 2026-07-29T11:57:13Z

Context

ast.Symbol is arena-allocated, so every byte of the struct is paid once per symbol, and a full check of a large program creates millions of them (VS Code's src reaches ~6.2 M). Its Members, Exports and ExportSymbol fields are only set on container and exported-declaration symbols. They are nil on every checker-created symbol and on most binder symbols, but they cost 24 bytes on all of them.

This PR

These three fields move into a small symbolExtra box that is allocated the first time one of them is set to a non-nil value, referenced from Symbol through a single pointer. Reads and writes go through Members()/SetMembers(), Exports()/SetExports() and ExportSymbol()/SetExportSymbol().

Memory

Pull request overview

Moves rarely populated symbol data behind a lazily allocated box, reducing 64-bit ast.Symbol size from 96 to 80 bytes while preserving compiler and language-service behavior.

Changes:

Adds lazy accessors for members, exports, and export symbols.
Migrates all affected consumers to the new API.
Adds layout and allocation tests.

`Members`, `Exports` and `ExportSymbol` are empty on nearly every symbol, so they now live in a lazily allocated box behind one pointer instead of three inline fields, with accessor methods for reads and writes. Setting nil never allocates a box, and `ast.GetMembers`/`GetExports` keep their create-if-nil behavior. The symbol ID stays inline because the paged link stores key symbol links by ID. No-Verification-Needed: test-only removal, product diff unchanged
