--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by David Malcolm <dmalc...@gcc.gnu.org>: https://gcc.gnu.org/g:fa29cf0c3f19b648e30b16fd2485c3c17a528a6e commit r10-7994-gfa29cf0c3f19b648e30b16fd2485c3c17a528a6e Author: David Malcolm <dmalc...@redhat.com> Date: Thu Dec 5 14:47:35 2019 -0500 Fix warning URLs for Fortran and analyzer [PR 92830] PR 92830 reports that we always use "gcc/Warning-Options.html" when we emit escaped documentation URLs when printing "[-Wname-of-option]" for a warning. This page is wrong for most Fortran warnings, and for analyzer warnings. I considered various schemes involving adding extra tags to the .opt format to capture where options are documented, but for now this patch fixes the issue by introducing some special-casing logic. It only fixes the URLs for warning options, not for other command-line options, but those are the only options for which get_option_url is currently called. gcc/ChangeLog: PR 92830 * configure.ac (DOCUMENTATION_ROOT_URL): Drop trailing "gcc/" from default value, so that it can by supplied by get_option_html_page. * configure: Regenerate. * opts.c: Include "selftest.h". (get_option_html_page): New function. (get_option_url): Use it. Reformat to place comments next to the expressions they refer to. (selftest::test_get_option_html_page): New. (selftest::opts_c_tests): New. * selftest-run-tests.c (selftest::run_tests): Call selftest::opts_c_tests. * selftest.h (selftest::opts_c_tests): New decl.
