gcc: M32C Options
1
1 3.18.20 M32C Options
1 --------------------
1
1 '-mcpu=NAME'
1 Select the CPU for which code is generated. NAME may be one of
1 'r8c' for the R8C/Tiny series, 'm16c' for the M16C (up to /60)
1 series, 'm32cm' for the M16C/80 series, or 'm32c' for the M32C/80
1 series.
1
1 '-msim'
1 Specifies that the program will be run on the simulator. This
1 causes an alternate runtime library to be linked in which supports,
1 for example, file I/O. You must not use this option when
1 generating programs that will run on real hardware; you must
1 provide your own runtime library for whatever I/O functions are
1 needed.
1
1 '-memregs=NUMBER'
1 Specifies the number of memory-based pseudo-registers GCC uses
1 during code generation. These pseudo-registers are used like real
1 registers, so there is a tradeoff between GCC's ability to fit the
1 code into available registers, and the performance penalty of using
1 memory instead of registers. Note that all modules in a program
1 must be compiled with the same value for this option. Because of
1 that, you must not use this option with GCC's default runtime
1 libraries.
