GCC for New Contributors¶
This is an unofficial guide to GCC’s internals, aimed at new developers, and at plugin authors.
I’m a relative newcomer to GCC, so I thought it was worth documenting some of the hurdles I ran into when I started working on GCC, to try to make it easier for others to start hacking on GCC. Hence this guide.
Other sources of information:
The official “Contributing to GCC” guide on the GCC website: https://gcc.gnu.org/contribute.html
The official GCC “internals” guide is: https://gcc.gnu.org/onlinedocs/gccint/
Another excellent resource is the material available at the website of the GCC Resource Center at IIT Bombay: https://www.cse.iitb.ac.in/grc/
There is also much information on the GCC wiki: https://gcc.gnu.org/wiki/HomePage though sadly much of it is out-of-date - GCC is (at the time of writing) a 30-year-old project.
