[flang][driver] Update PP tests to use the new driver Update the preprocessor regression tests to use the new driver if the new driver is built (FLANG_BUILD_NEW_DRIVER=On), otherwise the tests will still run using f18. Summary of changes: - Introduce %flang to the regression tests, which points to the new driver if it is built or otherwise points to f18 - Update all tests in flang/test/Preprocessing/ to use %flang Differential Revision: https://reviews.llvm.org/D94805 2021-01-25 20:07:17 +08:00			`!

[flang] Produce proper "preprocessor output" for -E option Rename the current -E option to "-E -Xflang -fno-reformat". Add a new Parsing::EmitPreprocessedSource() routine to convert the cooked character stream output of the prescanner back to something more closely resembling output from a traditional preprocessor; call this new routine when -E appears. The new -E output is suitable for use as fixed form Fortran source to compilation by (one hopes) any Fortran compiler. If the original top-level source file had been free form source, the output will be suitable for use as free form source as well; otherwise there may be diagnostics about missing spaces if they were indeed absent in the original fixed form source. Unless the -P option appears, #line directives are interspersed with the output (but be advised, f18 will ignore these if presented with them in a later compilation). An effort has been made to preserve original alphabetic character case and source indentation. Add -P and -fno-reformat to the new drivers. Tweak test options to avoid confusion with prior -E output; use -fno-reformat where needed, but prefer to keep -E, sometimes in concert with -P, on most, updating expected results accordingly.
