The following testcase fails on powerpc64-linux with GCC mainline
starting sometime after 2005-05-05 01:24 UTC:
long a, b;
void
foo ()
{
a = b + 2147483647L;
}
int
main ()
{
foo ();
return 0;
}
elm3b11% /opt/gcc-nightly/mline/bin/gcc -m64 -O0 -g bug.c
/tmp/ccwXjSlP.o(.text+0x28): In function `foo':
/home/janis/work/bug.c:6: undefined reference to `__adddi3'
collect2: ld returned 1 exit status
It looks like a problem with this patch from geoffk on 2005-05-05:
http://gcc.gnu.org/ml/gcc-cvs/2005-05/msg00232.html
This affects SPEC CPU2000 tests bzip2, eon, and gzip built without
optimization.

This is caused by Geoff's mode macros patch:
http://gcc.gnu.org/ml/gcc-patches/2005-05/msg00392.html
addsi3 and adddi3 had different operand predicates, but the patch combined the
patterns, using the addsi3 predicate. sub<mode>3 uses a helper, but add<mode>3
does not. testing a patch...
