4.5-rc1 builds and runs with CONFIG_CC_OPTIMIZE_FOR_SIZE=n here. It's a fairly minimal config though. >>>Toolchain used is the old gcc 4.2.4 toolchain from kernel.org.

There are patches for gcc 4.4.3 at http://distribute.atmel.no/tools/opensource/avr32-gcc/ The patches apply with only trivial fixes to 4.4.7 as well. I tried forward-porting to something newer, but my knowledge gcc internal voodoo wasn't sufficient. >>>Another question is if the avr32 kernel still supported, or if I should >>>just stop trying to build test it.

Even when it builds, it often doesn't work since non-DT support has bitrotted in many drivers. -- Måns Rullgård
