This is the default. 31 32nofpu 33Target RejectNegative Mask(NO_USE_FPU) Report 34Disable the use of RX FPU instructions. 35 36mnofpu 37Target RejectNegative Mask(NO_USE_FPU) MaskExists Undocumented 38 39fpu 40Target RejectNegative InverseMask(NO_USE_FPU) Report 41Enable the use of RX FPU instructions. This is the default. 42 43;--------------------------------------------------- 44 45mcpu= 46Target RejectNegative Joined Var(rx_cpu_name) Report 47Specify the target RX cpu type. 48 49patch= 50Target RejectNegative Joined Var(rx_cpu_name) 51Alias for -mcpu. 52 53;--------------------------------------------------- 54 55mbig-endian-data 56Target RejectNegative Mask(BIG_ENDIAN_DATA) Report 57Data is stored in big-endian format. 58 59mlittle-endian-data 60Target RejectNegative InverseMask(BIG_ENDIAN_DATA) Report 61Data is stored in little-endian format. (Default). 62 63;--------------------------------------------------- 64 65msmall-data-limit= 66Target RejectNegative Joined UInteger Var(rx_small_data_limit) Init(0) 67Maximum size of global and static variables which can be placed into the small data area. 68 69;--------------------------------------------------- 70 71msim 72Target 73Use the simulator runtime. 74 75;--------------------------------------------------- 76 77mas100-syntax 78Target Mask(AS100_SYNTAX) Report 79Generate assembler output that is compatible with the Renesas AS100 assembler. This may restrict some of the compiler's capabilities.
