1. Introduction

SDCC is a Free ware , retargettable, optimizing ANSI-C compiler. The current -version targets Intel 8051 based MCUs, it can be retargetted for other 8 bit -MCUs or PICs. The entire source code for the compiler is distributed under -GPL. SDCC used ASXXXX & ASLINK a Free ware, retargettable assembler & -linker. SDCC has extensive MCU (8051) specific language extensions, which lets -it utilize the underlying hardware effectively. The front-end (parser) will -be enhanced to handle language extensions for other MCUs as and when they are -targetted. In addition to the MCU Specific optimizations SDCC also does a host -of standard optimizations like global sub expression elimination, loop optimizations -(loop invariant, strength reduction of induction variables and loop reversing), -constant folding & propagation, copy propagation, dead code elimination -and jumptables for 'switch' statements. For the back-end SDCC uses a global -register allocation scheme which should be well suited for other 8 bit MCUs -, the peep hole optimizer uses a rule based substitution mechanism which is -MCU independent. Supported data-types are short (8 bits, 1 byte), char (8 bits, -1 byte), int (16 bits, 2 bytes ), long (32 bit, 4 bytes) & float (4 byte -IEEE). The compiler also allows inline assembler code to be embedded anywhere -in a function. In addition routines developed in assembly can also be called. -SDCC also provides an option to report the relative complexity of a function, -these functions can then be further optimized , or hand coded in assembly if -need be. SDCC also comes with a companion source level debugger SDCDB, the -debugger currently uses S51 a freeware simulator for 8051, it can be easily -modified to use other simulators. The latest version can be downloaded from -http://www.geocities.com/ResearchTriangle/Forum/1353 -

All packages used in this compiler system are opensource (freeware); source -code for all the sub-packages ( asxxxx assembler/linker , pre-processor and -gc a conservative garbage collector) are distributed with the package. Documentation -was created using a freeware word processor (LyX). -
