24 /* The macros here implement a set of templated vector types and
25 associated interfaces. These templates are implemented with
26 macros, as we're not in C++ land. The interface functions are
27 typesafe and use static inline functions, sometimes backed by
28 out-of-line generic functions. The vectors are designed to
29 interoperate with the GTY machinery.
30
31 Because of the different behavior of structure objects, scalar
32 objects and of pointers, there are three flavors, one for each of
33 these variants. Both the structure object and pointer variants
34 pass pointers to objects around -- in the former case the pointers
35 are stored into the vector and in the latter case the pointers are
36 dereferenced and the objects copied into the vector. The scalar
37 object variant is suitable for int-like objects, and the vector
38 elements are returned by value.
39
40 There are both 'index' and 'iterate' accessors. The iterator
41 returns a boolean iteration condition and updates the iteration
42 variable passed by reference. Because the iterator will be
43 inlined, the address-of can be optimized away.
44
45 The vectors are implemented using the trailing array idiom, thus
46 they are not resizeable without changing the address of the vector
47 object itself. This means you cannot have variables or fields of
48 vector type -- always use a pointer to a vector. The one exception
49 is the final field of a structure, which could be a vector type.
50 You will have to use the embedded_size & embedded_init calls to
51 create such objects, and they will probably not be resizeable (so
52 don't use the 'safe' allocation variants). The trailing array
53 idiom is used (rather than a pointer to an array of data), because,
54 if we allow NULL to also represent an empty vector, empty vectors
55 occupy minimal space in the structure containing them.
56
57 Each operation that increases the number of active elements is
58 available in 'quick' and 'safe' variants. The former presumes that
59 there is sufficient allocated space for the operation to succeed
60 (it dies if there is not). The latter will reallocate the
61 vector, if needed. Reallocation causes an exponential increase in
62 vector size. If you know you will be adding N elements, it would
63 be more efficient to use the reserve operation before adding the
64 elements with the 'quick' operation. This will ensure there are at
65 least as many elements as you ask for, it will exponentially
66 increase if there are too few spare slots. If you want reserve a
67 specific number of slots, but do not want the exponential increase
68 (for instance, you know this is the last allocation), use the
69 reserve_exact operation. You can also create a vector of a
70 specific size from the get go.
71
72 You should prefer the push and pop operations, as they append and
73 remove from the end of the vector. If you need to remove several
74 items in one go, use the truncate operation. The insert and remove
75 operations allow you to change elements in the middle of the
76 vector. There are two remove operations, one which preserves the
77 element ordering 'ordered_remove', and one which does not
78 'unordered_remove'. The latter function copies the end element
79 into the removed slot, rather than invoke a memmove operation. The
80 'lower_bound' function will determine where to place an item in the
81 array using insert that will maintain sorted order.
82
83 When a vector type is defined, first a non-memory managed version
84 is created. You can then define either or both garbage collected
85 and heap allocated versions. The allocation mechanism is specified
86 when the type is defined, and is therefore part of the type. If
87 you need both gc'd and heap allocated versions, you still must have
88 *exactly* one definition of the common non-memory managed base vector.
89
90 If you need to directly manipulate a vector, then the 'address'
91 accessor will return the address of the start of the vector. Also
92 the 'space' predicate will tell you whether there is spare capacity
93 in the vector. You will not normally need to use these two functions.
94
95 Vector types are defined using a DEF_VEC_{O,P,I}(TYPEDEF) macro, to
96 get the non-memory allocation version, and then a
97 DEF_VEC_ALLOC_{O,P,I}(TYPEDEF,ALLOC) macro to get memory managed
98 vectors. Variables of vector type are declared using a
99 VEC(TYPEDEF,ALLOC) macro. The ALLOC argument specifies the
100 allocation strategy, and can be either 'gc' or 'heap' for garbage
101 collected and heap allocated respectively. It can be 'none' to get
102 a vector that must be explicitly allocated (for instance as a
103 trailing array of another structure). The characters O, P and I
104 indicate whether TYPEDEF is a pointer (P), object (O) or integral
105 (I) type. Be careful to pick the correct one, as you'll get an
106 awkward and inefficient API if you use the wrong one. There is a
107 check, which results in a compile-time warning, for the P and I
108 versions, but there is no check for the O versions, as that is not
109 possible in plain C. Due to the way GTY works, you must annotate
110 any structures you wish to insert or reference from a vector with a
111 GTY(()) tag. You need to do this even if you never declare the GC
112 allocated variants.
113
114 An example of their use would be,
115
116 DEF_VEC_P(tree); // non-managed tree vector.
117 DEF_VEC_ALLOC_P(tree,gc); // gc'd vector of tree pointers. This must
118 // appear at file scope.
119
120 struct my_struct {
121 VEC(tree,gc) *v; // A (pointer to) a vector of tree pointers.
122 };
123
124 struct my_struct *s;
125
126 if (VEC_length(tree,s->v)) { we have some contents }
127 VEC_safe_push(tree,gc,s->v,decl); // append some decl onto the end
128 for (ix = 0; VEC_iterate(tree,s->v,ix,elt); ix++)
129 { do something with elt }
