--- Comment #1 from Kewen Lin <linkw at gcc dot gnu.org> ---
Confirmed, this requires one e300c3 cross build to reproduce:
2944│ for (; instance != NULL; instance = instance->next)
2945│ {
2946│ bool mismatch = false;
2947├───────────> tree nextparm = TYPE_ARG_TYPES (instance->fntype);
2948│
2949│ for (unsigned int arg_i = 0;
(gdb) p instance->fntype
$1 = <tree 0x0>
The overloaded bif fntype for RS6000_INST_VSEEQP relies on type usi_ftype_tf.
rs6000_instance_info[RS6000_INST_VSEEQP].fntype
= usi_ftype_tf;
if (float128_type_node)
usi_ftype_tf
= build_function_type_list ( unsigned_intSI_type_node,
float128_type_node,
NULL_TREE)
But on e300c3 there is no float128 type support (float128_type_node is NULL).
One thought seems to check instance->fntype first and take (skip) it as
mismatch if it's NULL.
