[cfe-dev] static analyzer warning question

[Nikola Smiljanic]

Try playing with -ccc-print-phases. I'm not sure if there's a way to start
both analyzer and compiler action. Compiler action is what reports the
warning, you can enable just this action with -fsyntax-only. But passing
both --analyze and -fsyntax-only doesn't seem to work.
