[Bug c/13148] New: ICE on altivec while building code with debug enabled (-g) [regression]

[lu_zero at gentoo dot org]

the following error happens if you try to build libavicodec (get it from mplayer
or ffmpeg)
I experienced the same bug on gcc-3.3.2+altivec constant fixes and with 3.4 took
from cvs HEAD branch, the same code builds fine with gcc-3.2.3.

gcc -W -Wall -Wno-unused-parameter -O2 -mcpu=7450 -mtune=7450 -maltivec
-mabi=altivec -g  -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 
-DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE
-c -o ppc/mpegvideo_altivec.o ppc/mpegvideo_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:9460

Disabling debug leads to miscompiled code.

Can you attach the preprocessed source?

Most likely caused by:
+2003-11-20  Fariborz Jahanian  <fjahanian@apple.com>
+           David Edelsohn  <edelsohn@gnu.org>
+
+       * calls.c (expand_call): Allocate new temp in pass1.
+       (store_one_arg): If PARALLEL, calculate excess using mode size of
+       rtvec elt. 
+       * expr.c (emit_push_insn): If PARALLEL, calculate offset using
+       mode size of rtvec elt.
+       * function.c (assign_parms): Use parm in register, if available.


Also see: <http://gcc.gnu.org/ml/gcc/2003-11/msg01162.html> so this causes a build 
failure also.

I have not tried the fix but I am going to reopen based on the fact that it might not be fixed.

still present on mainline (20031203). Any volunteers to reduce the testcase down to something 
managable? :-)

Most likely the same as bug 11983.
