[cfe-dev] Summer of Code idea -- detecting undefined behavior (fwd)

[John Regehr]

Oops-- just sent the message below to the main LLVM list, it probably 
would have been better sent to this list in the first place.

--------------------

Is anyone interested in a SoC project to further develop Clang's support for 
detecting undefined behaviors in C/C++?

This is actually a collection of many smaller projects ranging from very easy 
(detecting divide by zero) to rather nasty (detecting references to 
out-of-scope automatic variables).

If someone does this, I'm happy to help mentor, provide test cases, etc.

If done well, this would be a relatively high-impact project.  It would catch 
more errors than valgrind, be faster, and provide much better error messages.
