"""
Generate a driver/library benchmark based on DFA/PTA traces.
Usage:
PYTHONPATH=lib bin/generate-dfa-benchmark.py [options] <pta/dfa definition> [output.cc]
generate-dfa-benchmarks reads in a DFA definition and generates runs
(i.e., all words accepted by the DFA up to a configurable length). Each symbol
corresponds to a function call. If arguments are specified in the DFA
definition, each symbol corresponds to a function call with a specific set of
arguments (so all argument combinations are present in the generated runs).
Options:
--depth=<depth> (default: 3)
Maximum number of function calls per run
--instance=<name>
Override the name of the class instance used for benchmarking
--sleep=<ms> (default: 0)
How long to sleep between function calls.
