Info

ICCV8 for AVR – C Compiler for Atmel AVR.lst - an interspersed C and asm listing file. The object code and final addressesfor your program files are gathered into a single listing file..mp - a map file. It contains the symbol and size information of your program in aconcise form..o - an object file, produced by the assembler. An output executable file is theresult of linking multiple object files..s - for each C source file, an assembly output is generated by the compiler. Thisis deleted after a successful compile..s19 - a Motorola Motorola/Freescale S19 Record executable file.16
ICCV8 for AVR – C Compiler for Atmel AVRPragmas and ExtensionsThe C Preprocessor accepts compiler-specific extensions using the #pragma controland the equivalent C99 _Pragma() keyword; e.g., the following are equivalent:#pragma abs_address:0x1000_Pragma(“abs_address:0x1000”)This allows you to write a macro definition that expands to a pragma control line:#define EMOSFN(ty, f, param) PRAGMA(ctask eMOS__##f)#define PRAGMA(x)_Pragma(#x)...EMOSFN(void, MemFreeAll, (void))expands to#pragma ctask eMOS__MemFreeAllThe actual code (from our eMOS RTOS) defines EMOSFN multiple ways to get boththe ctask declaration and a function declaration with minimal typing, to minimizetypographical errors.#pragmaThe compiler accepts the following pragmas: #pragma warn messageEmits a warning message similar to the C preprocessor directive #warning. #pragma ignore_unused_var name1 name2 ...This must appear inside a function and specifies that the named arguments areintentionally unused so no warning message should be generated for them. #pragma interrupt_handler ::...This declares functions as interrupt handlers so that the compiler generates theinterrupt handler return instruction instead of the normal function return, andsaves and restores all the registers that the functions use. It also generates theinterrupt vectors based on the vector numbers. See Interrupt Handling. Thispragma must precede the function definitions.17
