Using the command dump_c, uclid will spit out a C file that can be either compiled or fed to another verification tool. At the moment supported veification commands are: unroll and induction The syntax is currently CBMC specific, but will be adapted in future to work for any SV comp tool

When is this actually used? And why is it plural?

ah yeah, I put that there because eventually I'm going to have to deal with bitvector comparisons being either signed or unsigned. So, if the comparison is signed, the operands need to be made signed, and if the comparison is unsigned, the operands need to be made unsigned. But currently it doesn't do that and I was hoping to come up with a better way of dealing with the signed/unsigned-ness of operators but haven't yet.

If you want to avoid clutter in the Operator class, you can have a helper function that just does a match on the operators to say if they are signed
