See PR40989. What I'd imagine for options enabled from pragmas / attributes is that there would be a record kept of the state of options before defaults were applied, and such a late-applied option would effectively be appended to those on the command line, with the defaults then reapplied to determine the options subsequently in effect (or in effect for an individual function, etc.). But for the -Werror=foo issue I'd have thought that making it send the -Wfoo option through the existing option processing machinery - as if both were specified consecutively on the command line - should suffice. That seems largely independent of my proposal, and avoids any issues with needing functions to be present for all front ends. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43687
