MN10300

These -m options are defined for Matsushita MN10300
       architectures:

       -mmult-bug
           Generate code to avoid bugs in the multiply instructions for
           the MN10300 processors.  This is the default.

       -mno-mult-bug
           Do not generate code to avoid bugs in the multiply
           instructions for the MN10300 processors.

       -mam33
           Generate code using features specific to the AM33 processor.

       -mno-am33
           Do not generate code using features specific to the AM33
           processor.  This is the default.

       -mam33-2
           Generate code using features specific to the AM33/2.0
           processor.

       -mam34
           Generate code using features specific to the AM34 processor.

       -mtune=cpu-type
           Use the timing characteristics of the indicated CPU type when
           scheduling instructions.  This does not change the targeted
           processor type.  The CPU type must be one of mn10300, am33,
           am33-2 or am34.

       -mreturn-pointer-on-d0
           When generating a function that returns a pointer, return the
           pointer in both "a0" and "d0".  Otherwise, the pointer is
           returned only in "a0", and attempts to call such functions
           without a prototype result in errors.  Note that this option
           is on by default; use -mno-return-pointer-on-d0 to disable
           it.

       -mno-crt0
           Do not link in the C run-time initialization object file.

       -mrelax
           Indicate to the linker that it should perform a relaxation
           optimization pass to shorten branches, calls and absolute
           memory addresses.  This option only has an effect when used
           on the command line for the final link step.

           This option makes symbolic debugging impossible.

       -mliw
           Allow the compiler to generate Long Instruction Word
           instructions if the target is the AM33 or later.  This is the
           default.  This option defines the preprocessor macro
           "__LIW__".

       -mno-liw
           Do not allow the compiler to generate Long Instruction Word
           instructions.  This option defines the preprocessor macro
           "__NO_LIW__".

       -msetlb
           Allow the compiler to generate the SETLB and Lcc instructions
           if the target is the AM33 or later.  This is the default.
           This option defines the preprocessor macro "__SETLB__".

       -mno-setlb
           Do not allow the compiler to generate SETLB or Lcc
           instructions.  This option defines the preprocessor macro
           "__NO_SETLB__".
