[cfe-dev] scan-build and paths spanning multiple files

[Jordan Rose]

There's not currently a great way to do it. There's an internal option named "-analyzer-output" which accepts the value "text", but the display is currently broken in that path notes aren't attached to their associated warnings. This wouldn't be too hard to fix, but no one's gotten around to it yet.

You could cheat by preprocessing the source first and then analyzing that, but the resulting syntax-colored HTML file is usually massive, bogging down many browsers.

Basically, no one's put in the effort for this. ...patches welcome?

Sorry,
Jordan
