URL: https://github.com/llvm/llvm-project/commit/82d9cb34a2782df04975abb5a86365546ffae867 DIFF: https://github.com/llvm/llvm-project/commit/82d9cb34a2782df04975abb5a86365546ffae867.diff LOG: [DebugInfo] convert btf_tag attrs to DI annotations for func parameters Generate btf_tag annotations for DILocalVariable. The annotations are represented as an DINodeArray in DebugInfo.
