Back-End differences between 4.2.1 and 4.3.1

Hi! I upgraded from GCC 4.2.1 to GCC 4.3.1. But with this new version I can't compile any program with my back-end which works with GCC 4.2.1. I get the following error message: empty-void.c: In function 'main': empty-void.c:15: error: unrecognizable insn: (insn 14 4 15 empty-void.c:14 (pa

GCC 3.3.3 not on GNU servers...
