I've seen claims that Darwin's linker is much more efficient than the GNU linker, though I haven't confirmed this.
:-) I have a vague recollection this is true (32=bit only).
If someone wants to post linux numbers and the command, I'll redo on my box.
make all && rm */libjava/? && time make all-target-libjava
type of thing. Better would be someone that has both Yellow dog and Darwin on the same hardware, but... don't know if we'll find that person.
[ pause ] Ok, here is what I get for mainline 20050428:
$ rm powerpc-apple-darwin8.0.0/libjava/.libs/libgcj.la $ rm powerpc-apple-darwin8.0.0/libjava/libgcj.la $ time make -j2 all-target-libjava real 3m44.677s user 1m15.000s sys 1m19.868s
