Performance

  • Development builds reach native output sooner. Exact executable cache hits route through the lightweight CLI before loading the compiler, while uncached dev builds use -O0 and split large LLVM programs and libraries into stable, parallel, independently cached objects. npm installation also warms toolchain-specific runtime, TLS, and dynamic-engine artifacts for later builds.
  • The TypeScript frontend asks the checker for less work. Lowering batches structure, reachable-body, call, receiver, and implicit-instance queries by phase, memoizes immutable type constituents, and avoids querying dead bodies or visibly non-object array candidates.

Fixes

  • Unsupported Array.from element shapes refuse cleanly. Mapper results that the backends cannot represent are diagnosed or deferred before emission instead of reaching a C emitter crash.
  • JSDoc record equality reads preserve dynamic property behavior. Dot and bracket reads used by strict-equality and missing-key probes now route through checked-dynamic lookup, preserving absent properties and object identity.
