I'm testing IRA on m68k (with IRA_COVER_CLASSES defined to { GENERAL_REGS, FP_REGS, LIM_REG_CLASSES }) and get a crash in process_regs_for_copy. It is called with
(insn 22 17 28 4 /cvs/gcc/libgcc/../gcc/libgcc2.c:169 (set (reg/i:SI 0 %d0) (subreg:SI (reg/v:DI 30 [ w ]) 4)) 36 {*movsi_m68k2} (expr_list:REG_DEAD (reg/v:DI 30 [ w ]) (nil))) and hard_regno becomes -1 due to offset2 == 1. I don't understand how substracting offset2 from REGNO (reg1) can make sense here.
