Before > you ask: yes, GCC did receive `-march=octeon' :) Tools requirements to build a kernel have become a little bit confusing. I'm sure there are more restrictions that I've forgot. * The Lemote 2F defconfig requires binutils 2.20 to build. * GCC 3.2 is a lost cause for building 64-bit kernels * GCC 3.3 is broken but can just about be kludged to build a 64-bit kernel. * GCC 4.4 or a patched older version is required to build a kernel O2 or Indigo² with R10000 processors. * GCC 3.2 used to work for the rest but it's a very long time since I tested this for a modern kernel. * Linux 2.6.29 and older need a GCC older than 4.4.0 to compile.
