[cfe-dev] User documentation for supported warnings and --analyze mode

[Ted Kremenek]

If you are comparing between GCC and Clang, are you more interested in static analyzer warnings, or compiler warnings?  The latter is a better apples-to-apples comparison of functionality between the two compilers.

The '--analyze' option is simply a driver hook for activating the static analyzer, which really should be considered an entirely different tool than the compiler itself.

As for documentation on either compiler warnings or static analyzer warnings, that area is severely lacking.  I'm working on documentation on the latter, and I think the goal is to eventually auto-generate the documentation for the compiler warnings, but that work isn't off the ground yet.
