* Make native installs portable and smaller - Support glibc 2.34 with portable compiler binaries and static LLVM helpers. - Bundle the host runtime and discover optional cross-target packs from project dependencies. - Add application build benchmarks covering latency, executable size, and memory. * Keep bootstrap tools available in Sandbox validation - Isolate Zig for native compiler bootstrap and glibc entropy contracts. - Preserve the existing toolchain scope for cache and corpus tests. * Fix portable compiler bootstrap linking - Keep native support objects compatible with the destination host linker. - Resolve installed targets using the host declared by the toolchain manifest.
scriptc LLVM code-generation helper
This out-of-process helper owns LLVM assembly and object emission for
scriptc. It is built against exactly LLVM 22.1.8 and currently contains only
the AArch64 backend. The shipping @scriptc/llvm-darwin-arm64 package builds
and carries the executable; the compiler resolves that package directly and
never searches PATH for this program.
The ordinary workspace pnpm -r build does not rebuild this release artifact.
On macOS arm64, install CMake, Ninja, and Homebrew llvm@22, then build it
explicitly when working on native emission or preparing a package:
$ brew install cmake ninja llvm@22
$ pnpm --filter @scriptc/llvm-darwin-arm64 build:native
The protocol is intentionally small and versioned:
The packaged helper itself requires macOS 15 or newer because that is the minimum version of the pinned LLVM bottle it statically links. Its emitted assembly and objects separately target macOS 14 via the triple below.
scriptc-llvm-codegen version --format=json
scriptc-llvm-codegen emit --input app.ll --output app.o --filetype obj \
--target arm64-apple-macosx14.0.0 --opt-level 2 \
--relocation-model pic --diagnostic-format json --source-path app.ts
Emission uses LLVM 22's default per-module O2 pipeline, including coroutine lowering, verifies before and after optimization, and publishes through a private sibling file so a failed or interrupted request cannot truncate the requested output.
