Structural Architecture

The Swift repository structure highlights its profound integration with LLVM infrastructure. The project maps standard compiler phases (AST, Parsing, IRGen, SILGen) directly into broad architectural folders.

  • Multi-phased LLVM generation mapping directly into physical library subdivisions.

Notable Directories

/lib/SIL

The Swift Intermediate Language engine heavily crucial to Swift's memory safety analysis.

/lib/AST

Core representation of parsing definitions across the environment.

/stdlib

The core Swift standard library implementations bundled alongside compiler outputs.
