I tested it with kaffe-1.1.7, gcc-4.0.3 and hardfloat. Neither softfloat
nor eabi worked. And I used ecj instead of jikes. I tested it on a
PXA270 based board.
Another problem with the jit was that doubles did not work. The kernel
floating point emulator expects doubles to get in fpa format while the
jit generates vfp format. Our customer did not need this, so I was lucky
I can test it with current CVS head once my Toolchain/rootfs setup is up
again. BTW The link seems to be broken, but that should not be a
problem. I can checkout the CVS.
