https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63499 --- Comment #3 from Zbigniew Jędrzejewski-Szmek zbyszek at in dot waw.pl --- So, there's no way to programmatically check whether a flag is supported, without resorting to grepping the output or something like that. Great.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63499 --- Comment #4 from Andrew Pinski pinskia at gcc dot gnu.org --- (In reply to Zbigniew Jędrzejewski-Szmek from comment #3) So, there's no way to programmatically check whether a flag is supported, without resorting to grepping the output or something like that. Great. No there is way just use the positive side rather than the no- option.
