Here is a list of known AVR GCC bugs:<http://rtems.org/phpwiki/index.php/GCCAVRBugs>As a Linux-hosted user, is 4.0.1 stable enough for me to spend some time getting to know it ? I'm running 3.4.3 right now, and am very happy with it - but smaller/faster code is always welcome. I'm cool building it all from source.
Personally I would still hesitate to use it in any type of production environment because of these two GCC bugs:
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21990> <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21107>Bug #21990 is a "wrong code" type bug and was submitted by Björn Haase. He stated in the beginning: "I have observed a wrong code bug that I judge to be so serious that IMHO one should discourage use of the avr port for 4.x.x until it is resolved."
Bug #21107 is an "ICE on valid" bug submitted by Martin Kögler and is a regression for 4.0/4.1.
Neither of these two bugs have been fixed yet. IMHO. YMMV. Eric Weddington
