Then, let's say we have one of such options. For example, let's call
it -Wx for this example. If the behaviour is consistent with other
"group" options like -Wall, then:
-Wx is enabled by default (like now)
-Wno-pedantic does not disable -Wx (like now)
-Wno-all doesn't disable the group elements? I'd think it should, or we
should warn that it's a useless option.
-Werror=pedantic implies -Werror=x ? (to mimic -pedantic-errors)
I would think so.
For example, -Wmain is enabled by default but also by -Wall and
-pedantic. However, -Werror=all does not enable -Werror=main. Is this
a bug or the desired behaviour?
Sounds like a bug to me.
-Wno-error=pedantic -Werror implies -Werror=x or -Wno-error=x? The
documentation only says that -Wno-error= does not imply anything.
This should work the same as -Wno-error=all does for errors that are
part of the "all" group.
I think the bit about -Wno-error not implying anything just means that
-Wno-error=foo does not imply either -Wfoo or -Wno-foo.
