sh-elf compiler segfaults with a null argument for emit_move_insn
when compiling gcc.c-torture/compile/20000804-1.c with -O1.
The gdb backtrace is
#0 emit_move_insn (x=0xb7c89e20, y=0x0) at ../../ORIG/trunk/gcc/expr.c:3275
#1 0x08262d94 in rest_of_handle_life () at ../../ORIG/trunk/gcc/flow.c:1560
#2 0x083d3eaa in execute_one_pass (pass=0x85f70e0)
at ../../ORIG/trunk/gcc/passes.c:871
Thus the problem occurs in rest_of_handle_life
1560 emit_move_insn (param.retval,
1561 CONST0_RTX (GET_MODE (param.retval)));
where param.retval is (reg:CDI 174) and CONST0_RTX (CDImode) is
NULL on this target.
