msim
Target
Use the simulator runtime.

mmul=
Target RejectNegative Joined Var(rl78_mul_type) Tolower Enum(rl78_mul_types) Init(MUL_UNINIT)
Selects the type of hardware multiplication and division to use (none/g13/g14).

Enum
Name(rl78_mul_types) Type(enum rl78_mul_types)

EnumValue
Enum(rl78_mul_types) String(g10) Value(MUL_NONE)

mallregs
Target Mask(ALLREGS) Optimization
Use all registers, reserving none for interrupt handlers.

mrelax
Target Optimization
Enable assembler and linker relaxation.  Enabled by default at -Os.

mcpu=
Target RejectNegative Joined Var(rl78_cpu_type) ToLower Enum(rl78_cpu_types) Init(CPU_UNINIT)
Selects the type of RL78 core being targeted (g10/g13/g14).  The default is the G14.  If set, also selects the hardware multiply support to be used.
