URL: https://github.com/llvm/llvm-project/commit/5c3a99760274a06f8cb7e7247ce69c2fde5fbf2a DIFF: https://github.com/llvm/llvm-project/commit/5c3a99760274a06f8cb7e7247ce69c2fde5fbf2a.diff LOG: [KeyInstr][Clang] Member initalization atom (#134640) This patch is part of a stack that teaches Clang to generate Key Instructions metadata for C and C++. RFC: https://discourse.llvm.org/t/rfc-improving-is-stmt-placement-for-better-interactive-debugging/82668 The feature is only functional in LLVM if LLVM is built with CMake flag LLVM_EXPERIMENTAL_KEY_INSTRUCTIONs. Eventually that flag will be removed.
