-;------------------------------
-; Macros I: Faux Instructions
-;
-; The following "faux instructions" are
-; implemented here as macros:
-;
-; MOVIP register,constant		MOVI with optional PFX & MOVHI, or BGEN
-; ADDIP register,constant		PFX and ADDI with optional PFX
-; SUBIP register,constant		PFX and SUBI with optional PFX
-; CMPIP register,constant		PFX and CMPI with optional PFX
-;
-; MOVI16 register,constant		PFX and MOVI
-; MOVI32 register,constant		PFX, MOVI, PFX, and MOVHI
-; MOVIA  register,constant		PFX and MOVHI on Nios32, and PFX and MOVI
-;
-; ANDIP register,constant		PFX and ANDI
-; ANDNIP register,constant		PFX and ANDN
-; ORIP register,constant		PFX and ORI
-; XORIP register,constant		PFX and XORI
-;
-; _BSR address						MOVIP address to %g7, and CALL
-; _BR address						MOVIP address to %g7, and JMP
-;
-; BEQ address						SKPS cc_nz and BR, has delay slot
-; BNE address						SKPS cc_z and BR, has delay slot
-; BLE address						SKPS cc_gt and BR, has delay slot
-; BLT address						SKPS cc_ge and BR, has delay slot
-; RESTRET							RESTORE and JMP %i7 
-;
-;-------------------------------
-; Macros II: Printing
-;
-; These macros are guaranteed *not*
-; to have branch delay slot after them.
-;
-; NM_PrintChar char
-; NM_Print "string"
-; NM_PrintLn "string"			Follows it with a carriage return
-; NM_PrintRegister reg			For debugging, prints register name & value
-;
-;-------------------------------
-; Macros III: Inline Debugging
-;
-; These macros print various information
-; using large sections of expanded inline code.
-; They each use either few or no registers.
-; Thus, they may be safely used in interrupt handlers.
-;
-; NM_D_TxChar char			print char to UART, affects no registers
-; NM_D_TxRegister char,char,register	prints the two characters, and the hex register value
