           Summary: ICE on code using altivec
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: agx at sigxcpu dot org

Hi,
this might be related to 11793, but the PR
claims that the problem is fixed in head. I'm still seeing a (though
different) ICE with -snapshot at the same line of code as in 11793:

$ /usr/lib/gcc-snapshot/bin/gcc -O4 --save-temps -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
In function `dct_quantize_altivec':

ppc/mpegvideo_altivec.c:512: internal compiler error: in
add_location_or_const_value_attribute, at dwarf2out.c:9453

The problem can again be worked around by removing the -O4 switch.
Preprocessed source is up at:
http://honk.physik.uni-konstanz.de/linux-mips/gcc/bugs/mpegvideo_altivec-snapshot.i
Please let me know if I can provide any further details.
Regards,

The reason why I claimed it was fixed on the mainline was because I was not using linux to test it, I 
was using darwin which defaults to stabs so this most definitally a dwarf-2 debuging problem.

Removing the -g should workaround the ICE but you get no debuging symbols.

somewhat reduced testcase

Down to 88 lines. That's probably about as far as I'll get it.

Looks like add_location_or_const_value_attribute needs to understand const_vector.

The patch as if does not apply cleably to gcc-3_3-branch.
Do you have a version for gcc-3.3.4?  Does it worth it?
