BFD/XCOFF: Fix storage class setting for weak defined symbols
Fix an issue with commit 8602d4fea60d ("Add AIX weak support"),
<https://sourceware.org/ml/binutils/2009-03/msg00189.html>, and use the
correct condition to set the storage class for weak defined symbols.
The context here is as follows:
else if ((h->root.type == bfd_link_hash_defined
|| h->root.type == bfd_link_hash_defweak)
&& h->smclas == XMC_XO)
{
BFD_ASSERT (bfd_is_abs_section (h->root.u.def.section));
isym.n_value = h->root.u.def.value;
isym.n_scnum = N_UNDEF;
if (h->root.type == bfd_link_hash_undefweak
&& C_WEAKEXT == C_AIX_WEAKEXT)
isym.n_sclass = C_WEAKEXT;
else
isym.n_sclass = C_EXT;
aux.x_csect.x_smtyp = XTY_ER;
}
so clearly the inner condition can never be true. Correct the condition
then to check for the `bfd_link_hash_defweak' symbol type instead here,
and in a similar place a little further down in the same function.
