Bug in ARM compiler

[Jörg Schön]

Hello!

I have discovered the following problem with the gcc compiler for the ARM
architecture:

 $ arm-linux-gcc -v

Reading specs from /usr/local/arm-linux/lib/gcc-lib/arm-linux/2.95.2/specs
gcc version 2.95.2 19991024 (release)

 $ arm-linux-gcc -O2 -funroll-loops -c buggy.c

buggy.c: In function `buggy':
buggy.c:29: internal error--unrecognizable insn:
(insn 427 316 312 (set (mem:SI (plus:SI (plus:SI (reg:SI 11 fp)
                    (const_int -4096 [0xfffff000]))
                (const_int -64 [0xffffffc0])) 0)
        (reg:SI 12 ip)) -1 (nil)
    (nil))

 $

I have tried to strip down the buggy routine as much as possible. It seems 
that almost everything that is left is related to the bug.

Regards,
  Joerg Schoen
