Pass target specific information to the disassembler. Only supported on
some targets. Note only a single instance of the option on the
command line is supported. If the option occurs more than once, the
earlier versions will be ignored. If it is necessary to specify more
than one disassembler option then they should be placed together into
a space separated list. ie:
@smallexample
-M"first-disassembler-option second-disassembler-option"
@end smallexample
some targets. If it is necessary to specify more than one
disassembler option then multiple @option{-M} options can be used or
can be placed together into a comma separated list.
If the target is an ARM architecture then this switch can be used to
select which register name set is used during disassembler. Specifying
