--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #2) > Guess we'll have similar issue with C++ and modules as well (though they are > rarely used right now). Note we have had a similar issue with C and C++ with PCH too (though PCH is even less used and will even be less used as modules for C++ get phased in). And when those happen we have requested the preprocessed source for the PCH files too. modules and PCH both do decent output for the preprocessed source so we have been able to ask for those sources so far. For Fortran bug reports there has been one case were we needed to ask for the sources for the modules but that was years ago. Most of the fortran bug reports we have recieved so far, have been either reduced and single sources. In the ones which have not been have been not too bad to ask or get the sources that was being compiled. This is just my observations over the 20 years I have been doing first level triaging gcc bug reports.
