Bug#205899: gcc-3.3: [ppc] ICE on code using altivec



Package: gcc-3.3
Version: 1:3.3.2-0pre1
Severity: normal

Hi,
here's an ICE when building mplayer with altivec support on ppc:

gcc -O4   -pipe -ffast-math -fomit-frame-pointer -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -Wall -g -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -maltivec -mabi=altivec -c -o ppc/mpegvideo_altivec.o ppc/mpegvideo_altivec.c 
ppc/mpegvideo_altivec.c: In function `dct_quantize_altivec':
ppc/mpegvideo_altivec.c:512: error: unrecognizable insn:
(insn 1550 251 1551 2 (nil) (set (reg:V4SF 96 v19)
        (const_vector:V4SF [
                (const_double:SF 5.411961078643798828125e-1 [0x0.8a8bd4p+0])
                (const_double:SF 5.411961078643798828125e-1 [0x0.8a8bd4p+0])
                (const_double:SF 5.411961078643798828125e-1 [0x0.8a8bd4p+0])
                (const_double:SF 5.411961078643798828125e-1 [0x0.8a8bd4p+0])
            ])) -1 (nil)
    (nil))
ppc/mpegvideo_altivec.c:512: internal compiler error: in extract_insn, at recog.c:2175

Compiling without any -O switch works. Compiling with -snapshot gives
a different ICE at the same code line.
