Fixed on the mainline by http://gcc.gnu.org/ml/gcc-patches/2003-06/msg02445.html.
Aldy would you mind asking for this to go into the 3.3 branch after the release of 3.3.1.

[Bug target/11793] [3.3 regression] ICE in extract_insn, at recog.c:2175 (const_vector's)

This is a dup of 11092, which has not yet been fixed
on the 3.3 branch.  I verified the patch there works
fine, though.

I don't know if it's the same bug, but I just tried snapshot from gcc-3.4:
gcc -v
Reading specs from /usr/local/lib/gcc/powerpc-unknown-linux-gnu/3.4.0/specs
Configured with: ../gcc-3.4-20040114/configure --enable-altivec
Thread model: posix
gcc version 3.4.0 20040114 (experimental)

and got ICE compiling ffmpeg like this:

gcc -Wall  -maltivec -mabi=altivec -g -O3 -DHAVE_AV_CONFIG_H -I..
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -c -o
ppc/idct_altivec.o ppc/idct_altivec.c
ppc/mpegvideo_altivec.c: In function `dct_quantize_altivec':
ppc/mpegvideo_altivec.c:165: internal compiler error: in
add_location_or_const_value_attribute, at dwarf2out.c:9513
Please submit a full bug report,
with preprocessed source if appropriate.

Note the ICE in dwarf-2 for 3.4 is PR11983.
