Actually, figuring out kernel flags for fastest kernel compilation would be nice. Nice for bisect, and nice for slow machines. Zaurus needs 4 hours to compile kernel, kohjinsha cca 1.5 hours.
-O0 may not fly, as inlining is needed... some tests are neccessary. Now that we support icc, gcc -O0 should be doable, too...
...ok, so I tried -O0.
-O2 compilation took 1250seconds, -O0 took 1167seconds and failed.
is there some fast compiler around that could be used?
