protze.joachim added a comment. Thank you for working on this! It works for me. As you mentioned in D95460 <https://reviews.llvm.org/D95460>, this makes the behavior more similar to gcc.
I tested with `-Werror`: $ flang -fopenmp test-f77.f -ffree-form -c $ clang -fopenmp test-f77.o -ffree-form -lgfortran -Werror && echo $? clang-13: warning: command line option ‘-ffree-form’ is only valid in Flang mode (i.e. for Fortran input) clang-13: error: argument unused during compilation: '-ffree-form' [-Werror,-Wunused-command-line-argument] Since `-Werror` only raises the second warning, `-Wno-error=unused-command-line-argument` allows to successfully compile with `-Werror`. $ clang -fopenmp test-f77.o -ffree-form -lgfortran -Werror -Wno-error=unused-command-line-argument && echo $? clang-13: warning: command line option ‘-ffree-form’ is only valid in Flang mode (i.e. for Fortran input) clang-13: warning: argument unused during compilation: '-ffree-form' [-Wunused-command-line-argument] 0 I also tested with `-ffixed-form` and `-ffixed-line-length-132`. The latter doesn't work, while `-ffixed-line-length=132` works.
