+/* The macros here implement a set of templated vector types and
+ associated interfaces. These templates are implemented with
+ macros, as we're not in C++ land. The interface functions are
+ typesafe and use static inline functions, sometimes backed by
+ out-of-line generic functions. The vectors are designed to
+ interoperate with the GTY machinery.
+
+ Because of the different behavior of structure objects, scalar
+ objects and of pointers, there are three flavors, one for each of
+ these variants. Both the structure object and pointer variants
+ pass pointers to objects around -- in the former case the pointers
+ are stored into the vector and in the latter case the pointers are
+ dereferenced and the objects copied into the vector. The scalar
+ object variant is suitable for int-like objects, and the vector
+ elements are returned by value.
+
+ There are both 'index' and 'iterate' accessors. The iterator
+ returns a boolean iteration condition and updates the iteration
+ variable passed by reference. Because the iterator will be
+ inlined, the address-of can be optimized away.
+
+ The vectors are implemented using the trailing array idiom, thus
+ they are not resizeable without changing the address of the vector
+ object itself. This means you cannot have variables or fields of
+ vector type -- always use a pointer to a vector. The one exception
+ is the final field of a structure, which could be a vector type.
+ You will have to use the embedded_size & embedded_init calls to
+ create such objects, and they will probably not be resizeable (so
+ don't use the 'safe' allocation variants). The trailing array
+ idiom is used (rather than a pointer to an array of data), because,
+ if we allow NULL to also represent an empty vector, empty vectors
+ occupy minimal space in the structure containing them.
+
+ Each operation that increases the number of active elements is
+ available in 'quick' and 'safe' variants. The former presumes that
+ there is sufficient allocated space for the operation to succeed
+ (it dies if there is not). The latter will reallocate the
+ vector, if needed. Reallocation causes an exponential increase in
+ vector size. If you know you will be adding N elements, it would
+ be more efficient to use the reserve operation before adding the
+ elements with the 'quick' operation. This will ensure there are at
+ least as many elements as you ask for, it will exponentially
+ increase if there are too few spare slots. If you want reserve a
+ specific number of slots, but do not want the exponential increase
+ (for instance, you know this is the last allocation), use the
+ reserve_exact operation. You can also create a vector of a
+ specific size from the get go.
+
+ You should prefer the push and pop operations, as they append and
+ remove from the end of the vector. If you need to remove several
+ items in one go, use the truncate operation. The insert and remove
+ operations allow you to change elements in the middle of the
+ vector. There are two remove operations, one which preserves the
+ element ordering 'ordered_remove', and one which does not
+ 'unordered_remove'. The latter function copies the end element
+ into the removed slot, rather than invoke a memmove operation. The
+ 'lower_bound' function will determine where to place an item in the
+ array using insert that will maintain sorted order.
+
+ When a vector type is defined, first a non-memory managed version
+ is created. You can then define either or both garbage collected
+ and heap allocated versions. The allocation mechanism is specified
+ when the type is defined, and is therefore part of the type. If
+ you need both gc'd and heap allocated versions, you still must have
+ *exactly* one definition of the common non-memory managed base vector.
+
+ If you need to directly manipulate a vector, then the 'address'
+ accessor will return the address of the start of the vector. Also
+ the 'space' predicate will tell you whether there is spare capacity
+ in the vector. You will not normally need to use these two functions.
+
+ Vector types are defined using a DEF_VEC_{O,P,I}(TYPEDEF) macro, to
+ get the non-memory allocation version, and then a
+ DEF_VEC_ALLOC_{O,P,I}(TYPEDEF,ALLOC) macro to get memory managed
+ vectors. Variables of vector type are declared using a
+ VEC(TYPEDEF,ALLOC) macro. The ALLOC argument specifies the
+ allocation strategy, and can be either 'gc' or 'heap' for garbage
+ collected and heap allocated respectively. It can be 'none' to get
+ a vector that must be explicitly allocated (for instance as a
+ trailing array of another structure). The characters O, P and I
+ indicate whether TYPEDEF is a pointer (P), object (O) or integral
+ (I) type. Be careful to pick the correct one, as you'll get an
+ awkward and inefficient API if you use the wrong one. There is a
+ check, which results in a compile-time warning, for the P and I
+ versions, but there is no check for the O versions, as that is not
+ possible in plain C. Due to the way GTY works, you must annotate
+ any structures you wish to insert or reference from a vector with a
+ GTY(()) tag. You need to do this even if you never declare the GC
+ allocated variants.
+
+ An example of their use would be,
+
+ DEF_VEC_P(tree); // non-managed tree vector.
+ DEF_VEC_ALLOC_P(tree,gc); // gc'd vector of tree pointers. This must
+ // appear at file scope.
+
+ struct my_struct {
+ VEC(tree,gc) *v; // A (pointer to) a vector of tree pointers.
+ };
+
+ struct my_struct *s;
+
+ if (VEC_length(tree,s->v)) { we have some contents }
+ VEC_safe_push(tree,gc,s->v,decl); // append some decl onto the end
+ for (ix = 0; VEC_iterate(tree,s->v,ix,elt); ix++)
+ { do something with elt }

+/* Macros to invoke API calls. A single macro works for both pointer
