+This README file is copied into the directory for GCC-only header files
+when fixincludes is run by the makefile for GCC.
+
+Many of the files in this directory were automatically edited from the
+standard system header files by the fixincludes process.  They are
+system-specific, and will not work on any other kind of system.  They
+are also not part of GCC.  The reason we have to do this is because
+GCC requires ANSI C headers and many vendors supply ANSI-incompatible
+headers.
+
+Because this is an automated process, sometimes headers get "fixed"
+that do not, strictly speaking, need a fix.  As long as nothing is broken
+by the process, it is just an unfortunate collateral inconvenience.
+We would like to rectify it, if it is not "too inconvenient".

+This README file is copied into the directory for GCC-only header files
+when fixincludes is run by the makefile for GCC.
+
+Many of the files in this directory were automatically edited from the
+standard system header files by the fixincludes process.  They are
+system-specific, and will not work on any other kind of system.  They
+are also not part of GCC.  The reason we have to do this is because
+GCC requires ANSI C headers and many vendors supply ANSI-incompatible
+headers.
+
+Because this is an automated process, sometimes headers get "fixed"
+that do not, strictly speaking, need a fix.  As long as nothing is broken
+by the process, it is just an unfortunate collateral inconvenience.
+We would like to rectify it, if it is not "too inconvenient".

+
+/* Implementation of sparse integer sets as a linked list.
+
+   This sparse set representation is suitable for sparse sets with an
+   unknown (a priori) universe.  The set is represented as a double-linked
+   list of container nodes (struct bitmap_element).  Each node consists
+   of an index for the first member that could be held in the container,
+   a small array of integers that represent the members in the container,
+   and pointers to the next and previous element in the linked list.  The
+   elements in the list are sorted in ascending order, i.e. the head of
+   the list holds the element with the smallest member of the set.
+
+   For a given member I in the set:
+     - the element for I will have index is I / (bits per element)
+     - the position for I within element is I % (bits per element)
+
+   This representation is very space-efficient for large sparse sets, and
+   the size of the set can be changed dynamically without much overhead.
+   An important parameter is the number of bits per element.  In this
+   implementation, there are 128 bits per element.  This results in a
+   high storage overhead *per element*, but a small overall overhead if
+   the set is very sparse.
+
+   The downside is that many operations are relatively slow because the
+   linked list has to be traversed to test membership (i.e. member_p/
+   add_member/remove_member).  To improve the performance of this set
+   representation, the last accessed element and its index are cached.
+   For membership tests on members close to recently accessed members,
+   the cached last element improves membership test to a constant-time
+   operation.
+
+   The following operations can always be performed in O(1) time:
+
+     * clear			: bitmap_clear
+     * choose_one		: (not implemented, but could be
+				   implemented in constant time)
+
+   The following operations can be performed in O(E) time worst-case (with
+   E the number of elements in the linked list), but in O(1) time with a
+   suitable access patterns:
+
+     * member_p			: bitmap_bit_p
+     * add_member		: bitmap_set_bit
+     * remove_member		: bitmap_clear_bit
+
+   The following operations can be performed in O(E) time:
+
+     * cardinality		: bitmap_count_bits
+     * set_size			: bitmap_last_set_bit (but this could
+				  in constant time with a pointer to
+				  the last element in the chain)
+
+   Additionally, the linked-list sparse set representation supports
+   enumeration of the members in O(E) time:
+
+     * forall			: EXECUTE_IF_SET_IN_BITMAP
+     * set_copy			: bitmap_copy
+     * set_intersection		: bitmap_intersect_p /
+				  bitmap_and / bitmap_and_into /
+				  EXECUTE_IF_AND_IN_BITMAP
+     * set_union		: bitmap_ior / bitmap_ior_into
+     * set_difference		: bitmap_intersect_compl_p /
+				  bitmap_and_comp / bitmap_and_comp_into /
+				  EXECUTE_IF_AND_COMPL_IN_BITMAP
+     * set_disjuction		: bitmap_xor_comp / bitmap_xor_comp_into
+     * set_compare		: bitmap_equal_p
+
+   Some operations on 3 sets that occur frequently in data flow problems
+   are also implemented:
+
+     * A | (B & C)		: bitmap_ior_and_into
+     * A | (B & ~C)		: bitmap_ior_and_compl /
+				  bitmap_ior_and_compl_into
+
+   The storage requirements for linked-list sparse sets are O(E), with E->N
+   in the worst case (a sparse set with large distances between the values
+   of the set members).
+
+   The linked-list set representation works well for problems involving very
+   sparse sets.  The canonical example in GCC is, of course, the "set of
+   sets" for some CFG-based data flow problems (liveness analysis, dominance
+   frontiers, etc.).
+   
+   This representation also works well for data flow problems where the size
+   of the set may grow dynamically, but care must be taken that the member_p,
+   add_member, and remove_member operations occur with a suitable access
+   pattern.
+   
+   For random-access sets with a known, relatively small universe size, the
+   SparseSet or simple bitmap representations may be more efficient than a
+   linked-list set.  For random-access sets of unknown universe, a hash table
+   or a balanced binary tree representation is likely to be a more suitable
+   choice.
+
+   Traversing linked lists is usually cache-unfriendly, even with the last
+   accessed element cached.
+   
+   Cache performance can be improved by keeping the elements in the set
+   grouped together in memory, using a dedicated obstack for a set (or group
+   of related sets).  Elements allocated on obstacks are released to a
+   free-list and taken off the free list.  If multiple sets are allocated on
+   the same obstack, elements freed from one set may be re-used for one of
+   the other sets.  This usually helps avoid cache misses.
+
+   A single free-list is used for all sets allocated in GGC space.  This is
+   bad for persistent sets, so persistent sets should be allocated on an
+   obstack whenever possible.  */

+/* This header provides a declarative way of describing the types that
+   are used when declaring builtin functions.
+
+   Before including this header, you must define the following macros:
+
+   DEF_PRIMITIVE_TYPE (ENUM, TYPE)
+
+     The ENUM is an identifier indicating which type is being defined.
+     TYPE is an expression for a `tree' that represents the type.
+
+   DEF_FUNCTION_TYPE_0 (ENUM, RETURN)
+   DEF_FUNCTION_TYPE_1 (ENUM, RETURN, ARG1)
+   DEF_FUNCTION_TYPE_2 (ENUM, RETURN, ARG1, ARG2)
+   [...]
+
+     These macros describe function types.  ENUM is as above.  The
+     RETURN type is one of the enumerals already defined.  ARG1, ARG2,
+     etc, give the types of the arguments, similarly.
+
+   DEF_FUNCTION_TYPE_VAR_0 (ENUM, RETURN)
+   DEF_FUNCTION_TYPE_VAR_1 (ENUM, RETURN, ARG1)
+   DEF_FUNCTION_TYPE_VAR_2 (ENUM, RETURN, ARG1, ARG2)
+   [...]
+
+     Similar, but for function types that take variable arguments.
+     For example:
+
+       DEF_FUNCTION_TYPE_1 (BT_INT_DOUBLE, BT_INT, BT_DOUBLE)
+
+     describes the type `int ()(double)', using the enumeral
+     BT_INT_DOUBLE, whereas:
+
+       DEF_FUNCTION_TYPE_VAR_1 (BT_INT_DOUBLE_VAR, BT_INT, BT_DOUBLE)
+
+     describes the type `int ()(double, ...)'.
+
+  DEF_POINTER_TYPE (ENUM, TYPE)
+
+    This macro describes a pointer type.  ENUM is as above; TYPE is
+    the type pointed to.  */
