This turned out to be a regression introduced to gcc >= 4.8.5.
I sent a PR with fix:

kernel for powerpc/ibm4xx miscompiled by gcc >= 4.8.5
http://gnats.netbsd.org/51366

I also sent PRs related to ibm4xx:

kernel panic for powerpc/ibm4xx with "option DDB"
http://gnats.netbsd.org/51367

powerpc FPU emulation fails for single precision floating point arithmetic
http://gnats.netbsd.org/51368

kernel image for OpenBIOS not generated
http://gnats.netbsd.org/51369

I will appreciate it a lot, if you guys review and commit them.

Thanks,
Rin
