Most invalid instructions should default to break
Some invalid instructions, e.g. 0xFFFF,
should have an instruction-specific default, e.g. NOP.
A config file or command line option should allow a user
to change the global default to a compiled-in option,
e.g. NOP or abort.
A config file or command line option should allow the user
to change instruction-specific behavior to a compiled-in option,
e.g. change LPM R30, Z+ to NOP or to R30 = *(Z++) .
Use the GNU guys' @FILE mechanism to deal
with a multitude of command-line options.
For the brave and industrious,
a mechanism for run-time loading from a dynamic library might be useful.
What does simulavr currently do with LPM R30, Z+?
