[Bug target/14322] New: Unrecognizable lo_sum insn with -m64 and -fPIC

["ehrhardt at mathematik dot uni-ulm dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The following code gives an unrecognizable insn on sparc-sun-solaris
with -m64 -fPIC:

=================================
int foo;
void * f ()
{
        return &foo;
}
=================================

The error message is:

locale.cc: In function `f':
locale.cc:5: error: unrecognizable insn:
(insn 9 8 10 0 (set (reg:DI 112)
        (lo_sum:DI (reg:DI 112)
            (unspec:DI [
                    (symbol_ref:SI ("foo") <var_decl ff202d80 foo>)
                ] 0))) -1 (nil)
    (nil))
