Caroline Concatto d28de0d7f2 [Flang][Driver] Add PrintPreprocessedInput FrontendAction (`flang-new -E`) ... This patch implements the first frontend action for the Flang parser (i.e. Fortran::parser). This action runs the preprocessor and is invoked with the `-E` flag. (i.e. `flang-new -E <input-file>). The generated output is printed to either stdout or the output file (specified with `-` or `-o <output-file>`). Note that currently there is no mechanism to map options for the frontend driver (i.e. Fortran::frontend::FrontendOptions) to options for the parser (i.e. Fortran::parser::Options). Instead, Frotran::parser::options are hard-coded to: ``` std::vector<std::string> searchDirectories{"."s}; searchDirectories = searchDirectories; isFixedForm = false; _encoding(Fortran::parser::Encoding::UTF_8); ``` These default settings are compatible with the current Flang driver. Further work is required in order for CompilerInvocation to read and map clang::driver::options to Fortran::parser::options.
