This patch fixes LLDB data formatter support for llvm::Expected<T> with the following changes: llvm/utils/lldbDataFormatters.py: Fix ExpectedSynthProvider to handle non-templated storage types (e.g., int, int*). Previously the formatter only worked with templated storage types like std::reference_wrapper<T>. cross-project-tests/lit.cfg.py: Fix get_lldb_version_string() to use locally-built LLDB on non-Darwin platforms instead of system LLDB Fix minimum version from "1900" to "19.0.0" (typo in original code) New test files: Added expected.cpp and expected.test to test the formatter with Expected<int> and Expected<int*>. --------- Co-authored-by: Jeffrey Tan <jeffreytan@fb.com>
