I recently forgot a comma in a defm argument list and tablegen just failed with exit code 1 without printing an error message. I believe this issue was introduced in a9fc44c5573208859c2550382755098d750fc47d. This change prints the following instead: .../clang/include/clang/Driver/Options.td:569:3: error: Expected comma before next argument Reviewed By: Paul-C-Anagnostopoulos Differential Revision: https://reviews.llvm.org/D100178
