This file describes the implementation notes of the GNU C Compiler for the ATMEL AVR micro controllers family. The generated assembly code requires the GNU assembler (GAS). This is a part of the binutils package. Patches against binutils-2.9.5.0.13 can be obtained from http://home.overta.ru/users/denisc. This site also has patches for the GNU debugger (GDB). GCC can be configured as a cross compiler for the AVR architectures on the same system. Use `configure --target=avr --enable-languages="c"' to configure GCC. Further installation notes and other useful information about AVR tools can also be obtained from: http://home.overta.ru/users/denisc http://www.itnet.pl/amelektr/avr/ Mailing list, avr-gcc-list@avr.jpk.co.nz, exists to discuss related issues and suggestions for further optimizations and improvements.
