[cfe-dev] SMT solvers in clang SA

[Mikhail Ramalho via cfe-dev]

We are currently implementing the backends for other solvers (you can
follow the progress here: https://github.com/mikhailramalho/clang). So far
we got Boolector, MathSAT and Yices ready. CVC4 should be done soon.

When used to refute bugs, they all give roughly the same results: a ~5%
speedup if there are refuted bugs or a ~5% slowdown if no bug is refuted.

I've only tried to analyze one full project (tmux) with Yices; the CSA ran
for 24hrs and it didn't complete the analyze. For comparison, it takes 90s
to analyze it with the ranged constraint manager in the CSA.

Thanks,
