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 protocol is intentionally small and versioned:
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.
