3. L Toolset Background AVR 32 bit GNU Toolchain is a collection of executable software development tools for the Atmel AVR 32 bit processor These software development tools include Compilers e Assembler Linker e Librarian e File converter e Other file utilities e C Library Compiler The compiler is the GNU Compiler Collection or GCC This compiler is incredibly flexible and can be hosted on many platforms it can target many different different processors operating systems back ends and can be configured for multiple different languages front ends The GCC included is targeted for the AVR 32 bit processor and is configured to compile C or C Because this GCC is targeted for the AVR 32 bit the main executable that is created is prefixed with the target name avr32 gcc It is also referred to as AVR 32 bit GCC avr32 gcc is just a driver program only The compiler itself is called cc1 exe for C or cc1plus exe for C Also the preprocessor cpp exe will usually automatically be prepended with the target name avr32 cpp exe The actual set of component programs called is usually derived from the suffix of each source code file being processed GCC compiles a high level computer language into assembly and that is all It cannot work alone GCC is coupled with another project GNU Binutils which provides the assembler linker librarian and more Since GCC is just a driver program it can
