From b9ee7c6bfdbfcc722f3e4c8bd8378cccd4311740 Mon Sep 17 00:00:00 2001 From: Patrick Palka Date: Mon, 24 Apr 2023 10:33:49 -0400 Subject: c++, tree: declare some basic functions inline The functions strip_array_types, is_typedef_decl, typedef_variant_p and cp_expr_location are used throughout the C++ front end including in some fairly hot parts (e.g. in the tsubst routines and cp_walk_subtree) and they're small enough that the overhead of calling them out-of-line is relatively significant. So this patch moves their definitions into the appropriate headers to enable inlining them. gcc/cp/ChangeLog: * cp-tree.h (cp_expr_location): Define here. * tree.cc (cp_expr_location): Don't define here. gcc/ChangeLog: * tree.cc (strip_array_types): Don't define here. (is_typedef_decl): Don't define here. (typedef_variant_p): Don't define here. * tree.h (strip_array_types): Define here. (is_typedef_decl): Define here. (typedef_variant_p): Define here. --- gcc/tree.h | 32 +++++++++++++++++++++++++++++--- 1 file changed, 29 insertions(+), 3 deletions(-) (limited to 'gcc/tree.h') diff --git a/gcc/tree.h b/gcc/tree.h index 8e67e70..dc94c17 100644 --- a/gcc/tree.h +++ b/gcc/tree.h @@ -4821,9 +4821,20 @@ tree_to_poly_uint64 (const_tree t) extern int tree_int_cst_sgn (const_tree); extern int tree_int_cst_sign_bit (const_tree); extern unsigned int tree_int_cst_min_precision (tree, signop); -extern tree strip_array_types (tree); extern tree excess_precision_type (tree); +/* Recursively examines the array elements of TYPE, until a non-array + element type is found. */ + +inline tree +strip_array_types (tree type) +{ + while (TREE_CODE (type) == ARRAY_TYPE) + type = TREE_TYPE (type); + + return type; +} + /* Desription of the reason why the argument of valid_constant_size_p is not a valid size. */ enum cst_size_error { @@ -5374,8 +5385,6 @@ extern tree create_artificial_label (location_t); extern const char *get_name (tree); extern bool stdarg_p (const_tree); extern bool prototype_p (const_tree); -extern bool is_typedef_decl (const_tree x); -extern bool typedef_variant_p (const_tree); extern bool auto_var_p (const_tree); extern bool auto_var_in_fn_p (const_tree, const_tree); extern tree build_low_bits_mask (tree, unsigned); @@ -5391,6 +5400,23 @@ extern void error_unavailable_use (tree, tree); extern tree cache_integer_cst (tree, bool might_duplicate = false); extern const char *combined_fn_name (combined_fn); +/* Returns true if X is a typedef decl. */ + +inline bool +is_typedef_decl (const_tree x) +{ + return (x && TREE_CODE (x) == TYPE_DECL + && DECL_ORIGINAL_TYPE (x) != NULL_TREE); +} + +/* Returns true iff TYPE is a type variant created for a typedef. */ + +inline bool +typedef_variant_p (const_tree type) +{ + return is_typedef_decl (TYPE_NAME (type)); +} + /* Compare and hash for any structure which begins with a canonical pointer.
