GCC < 3.4.x (We use GCC 3.3.3 in our ELDK).
Unfortunately gcc 3.4.x produces faster code for PPC. We compile U-Boot with the eldk compiler and everything else with gcc-3.4.3 (buildroot toolchain).
IIRC, the difference was about >10-15% for parsing mpeg streams.
I've compiled U-Boot & Kernel with 3.4.2... the only thing that seems to fail in this process (obscurely) is hello_world, whereas the rest of the tree seems quite happy to compile *without* error/warning !
Granted.. U-Boot doesn't currently actually boot on my board, but, /that's/ just a matter of time/proffering sacrifice to the gods of SDRAM-UPM configuration. Easy !
