RISC-V: Add support for the XAndesvdot ISA extension.
This extension defines vector instructions to calculae of the signed/unsigned
dot product of four SEW/4-bit data and accumulate the result into a SEWbit
element for all elements in a vector register.
gcc/ChangeLog:
* config/riscv/andes-vector-builtins-bases.cc (nds_vd4dot): New class.
(class nds_vd4dotsu): New class.
* config/riscv/andes-vector-builtins-bases.h: New def.
* config/riscv/andes-vector-builtins-functions.def (nds_vd4dots): Ditto.
(nds_vd4dotsu): Ditto.
(nds_vd4dotu): Ditto.
* config/riscv/andes-vector.md
(@pred_nds_vd4dot<su><mode>): New pattern.
(@pred_nds_vd4dotsu<mode>): New pattern.
* config/riscv/genrvv-type-indexer.cc (main): Modify sew of QUAD_FIX,
QUAD_FIX_SIGNED and QUAD_FIX_UNSIGNED.
* config/riscv/riscv-vector-builtins.cc
(qexti_vvvv_ops): New operand information.
(qexti_su_vvvv_ops): New operand information.
(qextu_vvvv_ops): New operand information.
* config/riscv/riscv-vector-builtins.h (XANDESVDOT_EXT): New def.
(required_ext_to_isa_name): Add case XANDESVDOT_EXT.
(required_extensions_specified): Ditto.
(struct function_group_info): Ditto.
* config/riscv/vector-iterators.md (NDS_QUAD_FIX): New iterator.
