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

[Anna Zaks]

In addition, the analyzer's plist output does support multi-file paths. So depending on how you consume the output this might be useful. Note, we change the format of the plist often and do not guarantee supporting it forever. However, there are python utilities in clang/utils/analyzer that can help you parse the output (CmpRuns.py); these are mainly used for testing now.

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.
