M32C

-mcpu=name
           Select the CPU for which code is generated.  name may be one
           of r8c for the R8C/Tiny series, m16c for the M16C (up to /60)
           series, m32cm for the M16C/80 series, or m32c for the M32C/80
           series.

       -msim
           Specifies that the program will be run on the simulator.
           This causes an alternate runtime library to be linked in
           which supports, for example, file I/O.  You must not use this
           option when generating programs that will run on real
           hardware; you must provide your own runtime library for
           whatever I/O functions are needed.

       -memregs=number
           Specifies the number of memory-based pseudo-registers GCC
           uses during code generation.  These pseudo-registers are used
           like real registers, so there is a tradeoff between GCC's
           ability to fit the code into available registers, and the
           performance penalty of using memory instead of registers.
           Note that all modules in a program must be compiled with the
           same value for this option.  Because of that, you must not
           use this option with GCC's default runtime libraries.
