Your question is off-topic on this list, which is for development of
GCC, please use the gcc-help list for help using the compiler:

Because the fixed register means it no longer is a continuous
sequence of registers. And the PowerPC port does not break it up into two
sequences. And fixed registers in that range are not part of any standard
ABI.

I recently compiled the Debian archive (around 7000 packages that need
to be compiled) on HPPA (PA RISC) using trunk to identify new issues
before GCC 4.3 is released. I compiled the archive with optimization set
to -O3 and found the following ICEs with trunk from 20071212:
- PR34458: ICE in int
