Detailed Description
ACCESS represents each access to an aggregate variable (as a whole or a part). It can also represent a group of accesses that refer to exactly the same fragment of an aggregate (i.e. those that have exactly the same offset and size). Such representatives for a single aggregate, once determined, are linked in a linked list and have the group fields set. Moreover, when doing intraprocedural SRA, a tree is built from those representatives (by the means of first_child and next_sibling pointers), in which all items in a subtree are "within" the root, i.e. their offset is greater or equal to offset of the root and offset+size is smaller or equal to offset+size of the root. Children of an access are sorted by offset. Note that accesses to parts of vector and complex number types always represented by an access to the whole complex number or a vector. It is a duty of the modifying functions to replace them appropriately.
