SDCC has grown to be a large project. The compiler alone (without the preprocessor, assembler and linker) is well over 150,000 lines of code (blank stripped). The open source nature of this project is a key to its continued growth and support. You gain the benefit and support of many active software developers and end users. Is SDCC perfect? No, that's why we need your help. The developers take pride in fixing reported bugs. You can help by reporting the bugs and helping other SDCC users. There are lots of ways to contribute, and we encourage you to take part in making SDCC a great software package.
The SDCC project is hosted on the SDCC sourceforge site at http://sourceforge.net/projects/sdcc. You'll find the complete set of mailing lists, forums, bug reporting system, patch submission system, download area and Subversion code repository there.
