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.

I get this also for SPU-elf with gcc.c-torture/compile/20000804-1.c 
at -O3 -fomit-frame-pointer -funroll-loops.

Thanks,

Oh and it was the same emit_move_insn too.  So confirmed.

------- Comment #3 from kkojima at gcc dot gnu dot org  2006-11-30 00:26 -------
Thanks for the confirmation.  I've found that

#define CONST0_RTX(MODE) (const_tiny_rtx[0][(int) (MODE)])

and const_tiny_rtx[0][(int) CDImode] isn't initialized in
init_emit_once.  With adding

  for (mode = GET_CLASS_NARROWEST_MODE (MODE_COMPLEX_INT);
       mode != VOIDmode;
       mode = GET_MODE_WIDER_MODE (mode))
    const_tiny_rtx[0][(int) mode] = gen_rtx_raw_CONST_INT (mode, 0);

to init_emit_once, the segfault went away, though I'm not sure
whether it makes sense or not.

Well I am a maintainer of the SPU port so I really care about the failures and
how ever weird the testcase :).

I have to look into this more to figure out why we are getting a non concat for
the complex mode.

It seems that this ICE has gone away on mainline after the patch

        * cfgexpand.c (expand_one_var): Guard expand_one_stack_var by

for sh-elf at least.

------- Comment #6 from pinskia at gcc dot gnu dot org  2006-12-14 06:53 -------
The spu-elf part of this bug is not a regression, the reason why we have CDI
here is because spu-elf supports subregs of TI mode for CDI so we get that
mode.  Note the dataflow branch gets rid of this bug.
