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.
;---------------------------------------------------
