c: Add _Decimal64x support
The following patch adds _Decimal64x type support. Our dfp libraries (dpd & libbid) can only handle decimal32, decimal64 and decimal128 formats and I don't see that changing any time soon, so the following patch just hardcodes that _Decimal64x has the same mode as _Decimal128 (but is a distinct type). In the unlikely event some target would introduce something different that can be of course changed with target hooks but would be an ABI change. _Decimal128x is optional and we don't have a wider decimal type, so that type isn't added. 2024-11-15 Jakub Jelinek <jakub@redhat.com> gcc/ * tree-core.h (enum tree_index): Add TI_DFLOAT64X_TYPE. * tree.h (dfloat64x_type_node): Define. * tree.cc (build_common_tree_nodes): Initialize dfloat64x_type_node. * builtin-types.def (BT_DFLOAT64X): New DEF_PRIMITIVE_TYPE.
