Mainline bootstrap fails for x86_64-linux-gnu with PARALLEL change

[Andreas Jaeger <aj at suse dot de>]

Bootstrapping fails with current CVS mainline for me:
./xgcc -B./ -B/opt/gcc/3.4-devel/x86_64-suse-linux-gnu/bin/ -isystem /opt/gcc/3.4-devel/x86_64-suse-linux-gnu/include -isystem /opt/gcc/3.4-devel/x86_64-suse-linux-gnu/sys-include -L/builds/gcc/testing/gcc/../ld -O2  -DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes  -isystem ./include  -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED  -I. -I. -I/cvs/gcc/gcc -I/cvs/gcc/gcc/. -I/cvs/gcc/gcc/../include   -DL_negdi2 -c /cvs/gcc/gcc/libgcc2.c -o libgcc/./_negdi2.o
/cvs/gcc/gcc/libgcc2.c: In function `__negti2':

/cvs/gcc/gcc/libgcc2.c:71: internal compiler error: in add_location_or_const_value_attribute, at dwarf2out.c:9460
Please submit a full bug report,

The bootstrap failure is caused by this patch:

+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.


Here're some details:
