After all int64/double lowerings, there might still be 64b registers left which ir3 currently doesn't handle. This only happens in a small number of Piglit tests where those registers (or the variables they come from) did not get DCE'd. This patch handles 64b registers in ir3 by adding a NIR pass that does the following: - @decl_reg -> split in two 32b ones - @store_reg -> unpack_64_2x32_split_x/y and two separate stores - @load_reg -> two separate loads and pack_64_2x32_split After this pass, the 64b vecs used for the original loads/stores are still present and are also not handled yet by ir3. This patch removes them by running nir_lower_alu_to_scalar and nir_copy_prop.
