ICCV8 for AVR – C Compiler for Atmel AVRCompiler Arguments -A -ATurn on strict ANSI checking. Single -A turns on some ANSI checking. -eAccept extensions including 0b???? binary constants. See Pragmas andExtensions. -gGenerate debug information.When using with the driver, the following options must be used with the -Wf- prefix,such as -Wf-str_in_flash.Processor (best to use “Instruction Set” section below) -Mavr_enhancedGenerate enhanced core instructions and call and jmp. -Mavr_extendedSame as -Mavr_enhanced, plus 3 byte extended call and jmp addressing andextended function table in efunc_lit area. -Mavr_enhanced_smallGenerate enhanced core instructions but not call and jmp. -Mavr_megaGenerate ATMega instructions such as call and jmp instead of rcall andrjmp.Instruction Set -MEnhancedEnhanced core instructions. -MExtended3 byte extended call and jmp addressing and extended function table inefunc_lit area. -MHasMulUse the MUL and related instructions.158
ICCV8 for AVR – C Compiler for Atmel AVR-MLongJumpUse call/jmp instead of rcall/rjmp. -MXmegaGenerate XMega instructions.Others -const_is_flashTreat const the same as __flash. For backward compatibility only. -dfpEnable 64-bit double data type. The default is to treat double exactly the sameas float. Note that the code size will increase significantly and the executionspeed will decrease. Only available in the PROFESSIONAL version. -MISRA_CHECKEnable MISRA / Lint Code Checking. ADVANCED and PROFESSIONAL versionsonly. -O8Enable advanced optimizations. -O8 turns on the global optimizer MIO. MIOperforms classical function level optimizations such as constant propagation,common subexpression elimination through value numbering etc. -r20_23Do not use R20 to R23 for code generation. Useful if you want to reserve theseregisters as Global Registers. -str_in_flashAllocate literal strings in flash only.159
