I have two simple questions, I hope! 1. Is there a set of flags that, when compiling gcc, is meant to produce no warnings? I get a surfeit of warnings with my particular favorite options.
2. Are the libgcc functions warning_at() and error_at() intended for use by all front-ends? As of now, our COBOL front-end formats its own messages with fprintf(3). I would like to emulate normal gcc behavior, where warnings can be turned on and off, and (especially) elevated to errors with -Werror. I'm guessing we'd gain access to that functionality automatically if we engaged with the standard diagnositic framework, if there is one. I'm a little doubtful these are the keys to that kingdom, though. The comments regarding location_t and the location database seem very C-specific. --jkl
