Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |claziss at gcc dot gnu.org, | |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The general diagnostic rules we use say that diagnostics (gfortran/ diagnostics is an exception) shouldn't begin with a capital letter (unless such a word would be capitalized in the middle of a sentence too) and should not end with a dot, that is all violated here. As for what the DOC/DOC0/DOC1 expand too, it is easy to look up config/arc/arc-options.def where the strings are as the last argument of ARC_OPT or last two of ARC_OPTX. CCing the author of that, I know nothing about ARC otherwise.
