From: Jakub Jelinek <jakub@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r13-4260] c++: Fix up -fcontract* options Date: Wed, 23 Nov 2022 08:30:08 +0000 (GMT) [thread overview] Message-ID: <20221123083008.A7031385455F@sourceware.org> (raw) https://gcc.gnu.org/g:e1b503d7068cbaf4be938c02eb6686ea5a716fee commit r13-4260-ge1b503d7068cbaf4be938c02eb6686ea5a716fee Author: Jakub Jelinek <jakub@redhat.com> Date: Wed Nov 23 09:29:04 2022 +0100 c++: Fix up -fcontract* options I've noticed +FAIL: compiler driver --help=c++ option(s): "^ +-.*[^:.]\$" absent from output: " -fcontract-build-level=[off|default|audit] Specify max contract level to generate runtime checks for" error, this is due to missing dot at the end of the description. The second part of the first hunk should fix that, but while at it, I find it weird that some options don't have RejectNegative, yet for options that accept an argument a negative option looks weird and isn't really handled. Though, shall we have those [on|off] options at all? Those are inconsistent with all other boolean options gcc has. Every other boolean option is -fwhatever for it being on and -fno-whatever for it being off, shouldn't the options be without arguments and accept negatives (-fcontract-assumption-mode vs. -fno-contract-assumption-mode etc.)? 2022-11-23 Jakub Jelinek <jakub@redhat.com> * c.opt (fcontract-assumption-mode=, fcontract-continuation-mode=, fcontract-role=, fcontract-semantic=): Add RejectNegative. (fcontract-build-level=): Terminate description with dot.
