https://github.com/charles-zablit created https://github.com/llvm/llvm-project/pull/231128
This test uses FileCheck to check a full lldb session line by line. Changes to lldb's output break it even when the PDB reader is fine. Everything it checks about the reader is already covered:
- AST: `NativePDB/ast-functions.cpp` checks the same main declaration with the same lines.
- Reading params and locals in a live process: `NativePDB/variables-locations.test` and `NativePDB/stack_unwinding01.cpp`, plus about 30 STL data formatter API tests with `TEST_WITH_PDB_DEBUG_INFO`.
- Expressions on params and locals: `NativePDB/inline_sites_live.cpp`.
- Line tables and stepping: `NativePDB/break-by-line.cpp` and `TestDataFormatterStdString`.
Location ranges that change between addresses are covered by `NativePDB/local-variables-registers.s`.
