* tree-cfg.c (gimplify_val): Move from tree-complex.c. (gimplify_build1): Move from tree-complex.c do_unop. (gimplify_build2): Move from tree-complex.c do_binop. (gimplify_build3): New. * tree-complex.c (gimplify_val, do_unop, do_binop): Remove. Adjust throughout to call the functions above. * tree-flow.h: Declare the functions above. * tree-nested.c (gimplify_val): Rename to... (tsi_gimplify_val): ... this. * Makefile.in (tree_complex.o): Update dependencies. (stor-layout.o): Depend on regs.h. * c-common.c (handle_vector_size_attribute): Update for vector types without corresponding vector modes. * expr.c (expand_expr): Treat VECTOR_CST's like CONSTRUCTORS if a corresponding vector mode is not available. * print-tree.c (print_node): Print nunits for vector types * regclass.c (have_regs_of_mode): New. (init_reg_sets_1): Initialize it and use it instead of allocatable_regs_of_mode. * regs.h (have_regs_of_mode): Declare it. * stor-layout.c (layout_type): Pick a mode for vector types. * tree-complex.c (build_word_mode_vector_type, tree_vec_extract, build_replicated_const, do_unop, do_binop, do_plus_minus, do_negate, expand_vector_piecewise, expand_vector_parallel, expand_vector_addition, expand_vector_operations_1, expand_vector_operations, tree_lower_operations, pass_lower_vector_ssa, pass_pre_expand): New. (expand_complex_operations, pass_lower_complex): Remove. * tree-optimize.c (init_tree_optimization_passes): Adjust pass ordering for changes in tree-complex.c. * tree-pass.h: Declare new passes. * tree.c (finish_vector_type): Remove. (make_vector_type): New. (build_vector_type_for_mode, build_vector_type): Rewritten. * tree.def (VECTOR_TYPE): Document where the number of subparts is stored. * tree.h (TYPE_VECTOR_SUBPARTS): Use TYPE_PRECISION field. (make_vector): Remove declaration. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@85039 138bc75d-0d04-0410-961f-82ee72b054a4
