For lack of better organization, many general purpose flags are folded into the -f option. Unless otherwise noted, all -f options have a no- prefixed counterpart, so -f no-disassemble is the intuitive negation of -f disassemble. Later options always override earlier options.
Run additional internal graph (nodes and edges) consistency checks. Enabled by default.
Diagnostic tool. Produce a textual dump of expression allocation after the internal whole-program graph has been constructed.
Produce a textual netlist of the whole-program event graph in dot format 1. A list of options that tune this output can be found in Graph Generation.
Actually run the simulator's interpreter. Enabled by default. ‘-f no-run’ is explicitly needed when all that is desired are diagnostic dumps.
Print names of functions as they are loaded from dlopened modules. Default on. Mostly useful for diagnostics.
[1] dot is the name of a program (and its input language) that is part of AT&T's GraphViz package (open-source).
