Packaged built for hardfloat will run (with in-kernel CP1 emulation) but uf they interface with softfloat libraries there will be troubles (obviously).<br>I have one such binary-only app (coreplayer) which just outputs static noise instead of audible sound.<br>
Both GCC and glibc have to be built with softfloat otherwise one will break the other, with sometimes random (seg)faults.<br><br>Manuel<br>
