| 34 | /* Templated vector type and associated interfaces. | ||||
| 35 | |||||
| 36 | The interface functions are typesafe and use inline functions, | ||||
| 37 | sometimes backed by out-of-line generic functions. The vectors are | ||||
| 38 | designed to interoperate with the GTY machinery. | ||||
| 39 | |||||
| 40 | There are both 'index' and 'iterate' accessors. The index accessor | ||||
| 41 | is implemented by operator[]. The iterator returns a boolean | ||||
| 42 | iteration condition and updates the iteration variable passed by | ||||
| 43 | reference. Because the iterator will be inlined, the address-of | ||||
| 44 | can be optimized away. | ||||
| 45 | |||||
| 46 | Each operation that increases the number of active elements is | ||||
| 47 | available in 'quick' and 'safe' variants. The former presumes that | ||||
| 48 | there is sufficient allocated space for the operation to succeed | ||||
| 49 | (it dies if there is not). The latter will reallocate the | ||||
| 50 | vector, if needed. Reallocation causes an exponential increase in | ||||
| 51 | vector size. If you know you will be adding N elements, it would | ||||
| 52 | be more efficient to use the reserve operation before adding the | ||||
| 53 | elements with the 'quick' operation. This will ensure there are at | ||||
| 54 | least as many elements as you ask for, it will exponentially | ||||
| 55 | increase if there are too few spare slots. If you want reserve a | ||||
| 56 | specific number of slots, but do not want the exponential increase | ||||
| 57 | (for instance, you know this is the last allocation), use the | ||||
| 58 | reserve_exact operation. You can also create a vector of a | ||||
| 59 | specific size from the get go. | ||||
| 60 | |||||
| 61 | You should prefer the push and pop operations, as they append and | ||||
| 62 | remove from the end of the vector. If you need to remove several | ||||
| 63 | items in one go, use the truncate operation. The insert and remove | ||||
| 64 | operations allow you to change elements in the middle of the | ||||
| 65 | vector. There are two remove operations, one which preserves the | ||||
| 66 | element ordering 'ordered_remove', and one which does not | ||||
| 67 | 'unordered_remove'. The latter function copies the end element | ||||
| 68 | into the removed slot, rather than invoke a memmove operation. The | ||||
| 69 | 'lower_bound' function will determine where to place an item in the | ||||
| 70 | array using insert that will maintain sorted order. | ||||
| 71 | |||||
| 72 | Vectors are template types with three arguments: the type of the | ||||
| 73 | elements in the vector, the allocation strategy, and the physical | ||||
| 74 | layout to use | ||||
| 75 | |||||
| 76 | Four allocation strategies are supported: | ||||
| 77 | |||||
| 78 | - Heap: allocation is done using malloc/free. This is the | ||||
| 79 | default allocation strategy. | ||||
| 80 | |||||
| 81 | - GC: allocation is done using ggc_alloc/ggc_free. | ||||
| 82 | |||||
| 83 | - GC atomic: same as GC with the exception that the elements | ||||
| 84 | themselves are assumed to be of an atomic type that does | ||||
| 85 | not need to be garbage collected. This means that marking | ||||
| 86 | routines do not need to traverse the array marking the | ||||
| 87 | individual elements. This increases the performance of | ||||
| 88 | GC activities. | ||||
| 89 | |||||
| 90 | Two physical layouts are supported: | ||||
| 91 | |||||
| 92 | - Embedded: The vector is structured using the trailing array | ||||
| 93 | idiom. The last member of the structure is an array of size | ||||
| 94 | 1. When the vector is initially allocated, a single memory | ||||
| 95 | block is created to hold the vector's control data and the | ||||
| 96 | array of elements. These vectors cannot grow without | ||||
| 97 | reallocation (see discussion on embeddable vectors below). | ||||
| 98 | |||||
| 99 | - Space efficient: The vector is structured as a pointer to an | ||||
| 100 | embedded vector. This is the default layout. It means that | ||||
| 101 | vectors occupy a single word of storage before initial | ||||
| 102 | allocation. Vectors are allowed to grow (the internal | ||||
| 103 | pointer is reallocated but the main vector instance does not | ||||
| 104 | need to relocate). | ||||
| 105 | |||||
| 106 | The type, allocation and layout are specified when the vector is | ||||
| 107 | declared. | ||||
| 108 | |||||
| 109 | If you need to directly manipulate a vector, then the 'address' | ||||
| 110 | accessor will return the address of the start of the vector. Also | ||||
| 111 | the 'space' predicate will tell you whether there is spare capacity | ||||
| 112 | in the vector. You will not normally need to use these two functions. | ||||
| 113 | |||||
| 114 | Notes on the different layout strategies | ||||
| 115 | |||||
| 116 | * Embeddable vectors (vec<T, A, vl_embed>) | ||||
| 117 | |||||
| 118 | These vectors are suitable to be embedded in other data | ||||
| 119 | structures so that they can be pre-allocated in a contiguous | ||||
| 120 | memory block. | ||||
| 121 | |||||
| 122 | Embeddable vectors are implemented using the trailing array | ||||
| 123 | idiom, thus they are not resizeable without changing the address | ||||
| 124 | of the vector object itself. This means you cannot have | ||||
| 125 | variables or fields of embeddable vector type -- always use a | ||||
| 126 | pointer to a vector. The one exception is the final field of a | ||||
| 127 | structure, which could be a vector type. | ||||
| 128 | |||||
| 129 | You will have to use the embedded_size & embedded_init calls to | ||||
| 130 | create such objects, and they will not be resizeable (so the | ||||
| 131 | 'safe' allocation variants are not available). | ||||
| 132 | |||||
| 133 | Properties of embeddable vectors: | ||||
| 134 | |||||
| 135 | - The whole vector and control data are allocated in a single | ||||
| 136 | contiguous block. It uses the trailing-vector idiom, so | ||||
| 137 | allocation must reserve enough space for all the elements | ||||
| 138 | in the vector plus its control data. | ||||
| 139 | - The vector cannot be re-allocated. | ||||
| 140 | - The vector cannot grow nor shrink. | ||||
| 141 | - No indirections needed for access/manipulation. | ||||

| 145 | * Space efficient vector (vec<T, A, vl_ptr>) | ||||
| 146 | |||||
| 147 | These vectors can grow dynamically and are allocated together | ||||
| 148 | with their control data. They are suited to be included in data | ||||
| 149 | structures. Prior to initial allocation, they only take a single | ||||
| 150 | word of storage. | ||||
| 151 | |||||
| 152 | These vectors are implemented as a pointer to embeddable vectors. | ||||
| 153 | The semantics allow for this pointer to be NULL to represent | ||||
| 154 | empty vectors. This way, empty vectors occupy minimal space in | ||||
| 155 | the structure containing them. | ||||
| 156 | |||||
| 157 | Properties: | ||||
| 158 | |||||
| 159 | - The whole vector and control data are allocated in a single | ||||
| 160 | contiguous block. | ||||
| 161 | - The whole vector may be re-allocated. | ||||
| 162 | - Vector data may grow and shrink. | ||||
| 163 | - Access and manipulation requires a pointer test and | ||||
| 164 | indirection. | ||||
| 165 | - It requires 1 word of storage (prior to vector allocation). | ||||

| 561 | thus they are not resizeable without changing the address of the | ||||
| 562 | vector object itself. This means you cannot have variables or | ||||
| 563 | fields of embeddable vector type -- always use a pointer to a | ||||
| 564 | vector. The one exception is the final field of a structure, which | ||||
| 565 | could be a vector type. | ||||
| 566 | |||||
| 567 | You will have to use the embedded_size & embedded_init calls to | ||||
| 568 | create such objects, and they will not be resizeable (so the 'safe' | ||||
| 569 | allocation variants are not available). | ||||
| 570 | |||||
| 571 | Properties: | ||||
| 572 | |||||
| 573 | - The whole vector and control data are allocated in a single | ||||
| 574 | contiguous block. It uses the trailing-vector idiom, so | ||||
| 575 | allocation must reserve enough space for all the elements | ||||
| 576 | in the vector plus its control data. | ||||
| 577 | - The vector cannot be re-allocated. | ||||
| 578 | - The vector cannot grow nor shrink. | ||||
| 579 | - No indirections needed for access/manipulation. | ||||
| 580 | - It requires 2 words of storage (prior to vector allocation). */ | ||||
