Regression in gcc-2.95 19990525

[H.J. Lu]

With gcc 2.95 19990525, I got this on x86:

# gcc -S -O3 -mcpu=i686 -march=i686 foo.c
foo.c: In function `main':
foo.c:27: Could not split insn
(insn 116 112 61 (set (reg/v:SI 5 %edi)
        (if_then_else:SI (ne:SI (reg/v:SI 3 %ebx)
                (mem/s:SI (plus:SI (mult:SI (reg/v:SI 4 %esi)
                            (const_int 4 [0x4]))
                        (reg:SI 0 %eax)) 3))
            (mem/s:SI (plus:SI (mult:SI (reg/v:SI 4 %esi)
                        (const_int 4 [0x4]))
                    (mem/f:SI (plus:SI (reg:SI 6 %ebp)
                            (const_int 12 [0xc])) 0)) 3)
            (reg/v:SI 5 %edi))) 414 {movsicc+2} (insn_list/j/c 112 (insn_list/j
138 (insn_list/j/c 112 (nil))))
    (expr_list:REG_DEAD (reg:SI 0 %eax)
        (nil)))

egcs 1.1.2 is ok. It is a new bug.
