Add design docs: LLVM GC integration and C/C++ header import#197
Merged
Conversation
… plan Documents an estimate for using LLVM's GCStrategy/gcroot/gcwrite framework alongside the existing Boehm GC, and a plan for generating tslang declarations from C/C++ headers via an in-process clang importer (AST-based mapping plus optional wrapper-emission/LLVM IR linking for ABI-correct struct-by-value calls).

Summary
docs/llvm-gc-integration.md— estimate of which parts of LLVM's GC framework (GCStrategy,gcattribute,llvm.gcroot,llvm.gcwrite, statepoints/stack maps) are applicable alongside the project's existing Boehm GC, phased by effort/benefit.docs/c-cpp-header-import.md— plan for converting C/C++ header declarations into tslang declarations, covering an AST-based clang importer (tsbindgen), C→tslang type mapping, and an ABI-safe wrapper-emission approach that links a clang-produced LLVM module into the compiler's own module.Test plan
