This is not a bug and more a want for explanation. If there is a better medium fot that kind of exchange (e-mail?), please feel free to indicate it.
I am running some benchmarks on various tools about SMT-LIB. One of the measuring stick is of course Z3. I am mostly interested as of now in the parsing time / AST construction.
Am I mistaken if I say that I can simulate/approximate a parse-only mode for Z3/SMT-LIB v2 by commenting line 2017 in src/parsers/smt2/smt2parser.cpp ? This is this line:
I am trying to not trigger the SMT solving engine of Z3 and just have something close to simple AST construction.
