[Bug target/21477] New: adddi3 becomes external reference rather than instruction on powerpc64

[janis at gcc dot gnu dot org]

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.
