[cfe-dev] Using scan-build with custom checker plugins

[Anna Zaks]

Hi Thomas,

I am not aware of anyone else using scan-build with plugin checkers. I think the best way to implement this would be to add command line options to scan-build to specify the plugins and have scan-build pass those on to c++-analyzer. This is how other flags are supported, for example, see "-enable-checker". Would be great if you submit the patch for this to the open source codebase!

Cheers,
Anna.
