  "message": "[CIR] Add MLIR ABI Lowering design document\n\nDesign document for MLIR dialect-agnostic calling convention\nlowering that builds on the LLVM ABI Lowering Library\n(llvm/lib/ABI/) as the single source of truth for ABI\nclassification.  Dialects use the library via an adapter layer:\nABITypeMapper maps dialect types to abi::Type*, the library\nclassifies arguments and returns, and a dialect-specific\nABIRewriteContext applies the decisions back to IR operations.\n\nTargets x86_64 and AArch64, with parity against Classic Clang\nCodeGen validated through differential testing.",
