Info

ICCV8 for AVR – C Compiler for Atmel AVRDefine a link time constant. should be a symbol used in an assemblyinstruction and cannot be used in the assembly directive .if etc. -dhwstk_size:Define the size of the hardware stack. The hardware is allocated at the top ofSRAM, and then the software stack follows it. See Program Data and ConstantMemory. -dram_end:Define the end of the internal RAM area. This is used by the Startup File toinitialize the value of the hardware Stacks. For the classic non-Mega devices,ram_end is the size of the SRAM plus 96 bytes of IO and CPU registers minusone. For the Mega devices, it is the size of the SRAM minus one. External SRAMdoes not affect this value, since the hardware stack is always allocated in theinternal RAM for faster execution speed. -e:Specify the total flash size of the target device. -elim[:]Enable the Unused Code Elimination optimization. PRO versions only. -FFill unused ROM locations with pat. Pattern must be an integer. Use 0x prefix forhexadecimal integer. -fcoffOutput format is COFF. Note that if you have EEPROM data, it is always writtenas Intel HEX format in the .eep file. -fihx_coffOutput format is both COFF and Intel HEX. -fintelhexOutput format is Intel HEX. -gGenerate debug information. -LSpecify the library directory. Multiple directories may be specified and they aresearched in the reverse order (i.e., last directory specified is searched first).162
ICCV8 for AVR – C Compiler for Atmel AVR -lLink in the specific library files in addition to the default libcavr.a. This can beused to change the behavior of a function in the default library libcavr.a, sincethe default library is always linked in last. The libname is the library file namewithout the lib prefix and without the .a suffix. For example:-llpavr “liblpavr.a” using full printf-lfpavr “libfpavr.a” using floating-point printf -mSpecify the device name. This is emitted to the top of the .mp map file. -nb:Specify the Build number of the project. The linker emits the build number, thecompiler version and other documentary information to the top of the .mp mapfile. -RDo not link in the startup file or the default library file. This is useful if you arewriting an assembly-only application. -S0Generate COFF format compatible with AVR Studio 3.x. -S1Generate COFF format compatible with AVR Studio 4.00 to 4.05. -S2Generate COFF format compatible with AVR Studio 4.06+. -OEnable the Code Compression optimization. ADV or PRO versions only. -uUse as the startup file. If the file is just a name without path information,then it must be located in the library directory. -WTurn on relocation wrapping. See Device-Specific Instructions. Note that you needto use the -Wl prefix, since the driver does not know of this option directly (forexample,-Wl-W).163
