m32bit-doubles
Target RejectNegative Mask(32BIT_DOUBLES)
Stores doubles in 32 bits.

m64bit-doubles
Target RejectNegative InverseMask(32BIT_DOUBLES)
Store doubles in 64 bits.  This is the default.

fpu
Target RejectNegative Mask(32BIT_DOUBLES) MaskExists
Enable the use of RX FPU instructions.

nofpu
Target RejectNegative InverseMask(32BIT_DOUBLES) MaskExists
Disable the use of RX FPU instructions.

;---------------------------------------------------

mcpu=
Target RejectNegative Joined Var(rx_cpu_name)
Specify the target RX cpu type.

patch=
Target RejectNegative Joined Var(rx_cpu_name)
Alias for -mcpu.

;---------------------------------------------------

mbig-endian-data
Target RejectNegative Mask(BIG_ENDIAN_DATA)
Data is stored in big-endian format.

mlittle-endian-data
Target RejectNegative InverseMask(BIG_ENDIAN_DATA)
Data is stored in little-endian format.  (Default).

;---------------------------------------------------

msmall-data-limit=
Target RejectNegative Joined UInteger Var(rx_small_data_limit) Init(0)
Maximum size of global and static variables which can be placed into the small data area.

;---------------------------------------------------

msim
Target
Use the simulator runtime.

;---------------------------------------------------

mas100-syntax
Target Mask(AS100_SYNTAX)

;---------------------------------------------------

mrelax
Target
Enable linker relaxation.

;---------------------------------------------------

mmax-constant-size=
Target RejectNegative Joined UInteger Var(rx_max_constant_size) Init(0)
Maximum size in bytes of constant values allowed as operands.

;---------------------------------------------------

mint-register=
Target RejectNegative Joined UInteger Var(rx_interrupt_registers) Init(0)
Specifies the number of registers to reserve for interrupt handlers.

;---------------------------------------------------

msave-acc-in-interrupts
Target Mask(SAVE_ACC_REGISTER)
Specifies whether interrupt functions should save and restore the accumulator register.
