URL: https://github.com/llvm/llvm-project/commit/d3983310a4a65683d63ab6ab5af1a9bfde737128 DIFF: https://github.com/llvm/llvm-project/commit/d3983310a4a65683d63ab6ab5af1a9bfde737128.diff LOG: [lldb][unittests] Add LLDB_UNITTEST_STRIP_DEBUG_INFO to cut unittest link time (#203274) Add an opt-in cache option (default OFF). When ON, every target declared via `add_lldb_unittest` links without per-target debug info and dead-strips: - **MSVC**: `/DEBUG:NONE + /INCREMENTAL:NO + /OPT:REF + /OPT:ICF` - **clang/gcc**: `-g0 + LINKER:--strip-debug` (or `LINKER:-S` on macOS). This drastically speeds up linking the unittests executable when building with debug info on Windows.
