MCU + Open Source = ?

[psihodelia (Gast)]

What microcontrollers could be programmed with ONLY Open Source 
software?

Up to now,  I program AVR Atmega with "gcc" compiler and "avrdude" for 
connection with a board. The target code is perfect, short and fast. 
Avrdude is also a perfect tool.

I know also, that there is no Open Source software for 
Motorolla/Fresscale 8-bit microcontrollers (which is with the SpyderKit 
from Elektor journal). That's why I hate them, because I bought this 
SpyderKit.

Please, if you know any realy good Microcontroller that I can program 
with only Open Source tools (like gcc), tell me please. I am looking for 
any low-power MCU.

why open source and not "only freeware" ???

@Dirk:
But I cannot use non-open source software because of processors on my
host computers. I have PowerPCs and even some other CPU types (non x86
compatible). I have Gentoo Linux installed on all my computers, all
software is builded from source files. I cannot use precompiled binaries
because of non x86 architecture of my processors.

But what do you mean ist the "most easy way" to reach your destination?
Waiting for "open source compilers" for several cpu types or work
with a x86 compatible system and come to an end with your final project?

You might want to check the gcc documentation about the supported 
processors.
