The previous post in this series covered the broad OpenMP_tests frontend corpus: parseOmp in ast_only mode, hundreds of C and C++ cases, a mixed OpenMP/OpenACC slice, and a separate Fortran slice, all aimed at one question:

can the frontend build and unparse OpenMP ASTs correctly across a large corpus?

That still leaves a gap.

Some OpenMP regressions are too semantic for an AST-only text diff to catch cleanly, but they are still much earlier than lowering.
