[Bug target/28376] New: [4.1 Regression] ICE when building opensp with -O3 on alpha

[vapier at gentoo dot org]

when building opensp with gcc-4.1.1 and -O3 on alpha, gcc ICEs:

ice.ii: In function 'void __static_initialization_and_destruction_0(int, int)':
ice.ii:13: error: unrecognizable insn:
(insn 23 22 24 2 (set (reg:DI 84)
        (leu:DI (const_int 0 [0x0])
            (const_int 4 [0x4]))) -1 (nil)
    (nil))
ice.ii:13: internal compiler error: in extract_insn, at recog.c:2084

verified on Gentoo and Debian that 4.0.3 works, 4.1.1 fails, 4.2 works
