I don't understand.  There is no sim-common.[ch] file, and the new
module you are proposing is to go under sim/common.  It's as if you
want to add a new, alternative option handling module under
sim/common.  Can you describe what difficulties you encountered, when
trying to use the sim-options code as is (assuming you tried)?

The sim-options code can do this already, when used correctly.
Look at calls to sim_add_option_table in d30v, fr30, mips. m32r,
m68hc11, mn10300, ... :-)
