Re: more m68k breakage on m68k-linux

Hi,

hm.. the problem I see is that the register allocator is initialised
with random garbage. Eg FIXED_REGISTERS is 24 elts big, thus initial_fixed_regs[] is also only 24 elts and in init_reg_sets() we
copy a random 25th elt into fixed_regs[] and risk segfault.
I am pretty sure more it results in more damage later on.

I can confirm that it causes problems, after fixing FIXED_REGISTERS and CALL_USED_REGISTERS I can finally bootstrap gcc again, but my tree has another fix for a subtle miscompilation, which I still have to test separately. reg_class and all related macros still have to be fixed though.

bye, Roman
