[cfe-dev] [RFC][clang-tidy] Register warnings as check aliases

[Gábor Horváth via cfe-dev]

Hi!

I would like to propose that it should be possible to register compiler
warnings as clang-tidy check aliases.

As a motivating example, there is a CERT C++ secure coding rule: ERR54-CPP
[1]

This rule is covered by the clang warning: -Wexceptions

So turning on this check in clang tidy would have two effects: turning on
-Wexceptions and display the result of -Wexceptions as ERR54-CPP hits.

In my opinion aliases like this would be a great usability improvement:
 - it would be easier to check the code against some coding guidelines.
 - it would be easier to check what rules are already covered.
 - it would be easier to find uncovered rules to implement.

What do you think? Would you support a feature like that?

Regards,
Gabor
