Would you do the following for the failing assert?
p debug_rtx (insn)
p debug_rtx (i1)
p debug_rtx (substed)

If i1 or substed have been optimized away, you can get at them
in rtx_equal_p as using $r26 and $r25.

It's doubtful there will be a quick fix for this as the problem likely
isn't in the backend.

Dave

------- Comment #10 from danglin at gcc dot gnu dot org  2007-11-11 16:49 -------
This is a regression in reload.

(gdb) p debug_rtx (insn)
(insn 73 78 76 5 (set (mem/c:SI (plus:SI (reg/f:SI 3 %r3)
                (const_int 17888 [0x45e0])) [19 S4 A32])
        (plus:SI (reg/f:SI 3 %r3)
            (const_int 1056 [0x420]))) 114 {addsi3} (nil)
    (expr_list:REG_EQUIV (plus:SI (reg/f:SI 3 %r3)
            (const_int 1056 [0x420]))
        (nil)))

The problem is in the handling of the destination of insn 73.  The
constraints for the addsi3 pattern only accept register operands.
The pseudo in the lreg pass has been replaced by a temp which must
be reloaded.

I looked at pa_secondary_reload.  It simply returns NO_REGS for
(mem/c:SI (plus:SI (reg/f:SI 3 %r3) (const_int 17888 [0x45e0]))).
The frame offset in the temp exceeds that which can be handled
in a simple move.  So, an intermediate registers is needed.

------- Comment #11 from danglin at gcc dot gnu dot org  2007-11-11 23:28 -------
When delete_output_reload is called, we have:

(gdb) p debug_rtx (insn)
(insn 86 91 89 7 (set (mem/c:SI (plus:SI (reg/f:SI 3 %r3)
                (const_int 17900 [0x45ec])) [20 S4 A32])
        (plus:SI (reg/f:SI 3 %r3)
            (const_int 1068 [0x42c]))) 114 {addsi3} (nil)
    (expr_list:REG_EQUIV (plus:SI (reg/f:SI 3 %r3)
            (const_int 1068 [0x42c]))
        (nil)))

(gdb) p debug_rtx (reg_equiv_memory_loc[209])
(mem/c:SI (plus:SI (reg/f:SI 3 %r3)
        (const_int 17900 [0x45ec])) [20 S4 A32])
$20 = void
(gdb) p debug_rtx (reg_equiv_alt_mem_list[209])
(expr_list:REG_EQUIV (mem/c:SI (plus:SI (reg/f:SI 3 %r3)
            (const_int 17900 [0x45ec])) [20 S4 A32])
    (nil))

reg_equiv_memory_loc[209] is assigned to substed.  So, either the
substitution is wrong or reg_equiv_alt_mem_list[209] incorrectly
contains the substituted value.
