Soft-float has never been a supported configuration for PowerPC, as you can see from the fact that there's no separate dynamic linker name for it. I'm surprised it ever seemed to work -- surely setjmp/longjmp would be broken since they save/restore FPU registers. I don't think it would be hard to add though, and I'd welcome patches for it. What's needed is basically: - detection in configure, setting $SUBARCH there - dynamic linker name variants in arch/powerpc/reloc.h - separate subarch dir for soft-float in src/setjmp If you add soft-float it would probably make sense to add little-endian variant at the same time, if that's useful to anyone, since once you do the subarch work there's hardly any more work to make an endian variant too.
