12 /* d is valid when type == pet_expr_double
13 * i isl valid when type == pet_expr_int

16 * type is valid when type == pet_expr_cast
17 * op is valid otherwise
19 * If type_size is not zero, then the expression is of an integer type
20 * and type_size represents the size of the type in bits.
21 * If type_size is greater than zero, then the type is unsigned
22 * and the number of bits is equal to type_size.
23 * If type_size is less than zero, then the type is signed
24 * and the number of bits is equal to -type_size.
25 * type_size may also be zero if the size is (still) unknown.
27 * For each access expression inside the body of a statement, acc.ref_id
28 * is a unique reference identifier.
29 * acc.index represents the index expression, while acc.access
30 * represents the corresponding access relation.
31 * The output dimension of the index expression may be smaller
32 * than the number of dimensions of the accessed array (recorded
34 * The target space of the access relation, on the other hand,
35 * is equal to the array space.
36 * acc.access may be NULL if it can be derived directly from
37 * acc.index and acc.depth in construct_access_relation.
38 * That is, acc.access may be NULL if there are no additional
39 * constraints on the access relations.
40 * Both acc.index and acc.access usually map an iteration space
41 * to a (partial) data space.
42 * If the access has arguments, however, then the domain of the
43 * mapping is a wrapped mapping from the iteration space
44 * to a space of dimensionality equal to the number of arguments.
45 * Each dimension in this space corresponds to the value of the
46 * corresponding argument.
48 * The ranges of the index expressions and access relations may
49 * also be wrapped relations, in which case the expression represents
50 * a member access, with the structure represented by the domain
51 * of this wrapped relation and the member represented by the range.
52 * In case of nested member accesses, the domain is itself a wrapped
55 * If the data space is unnamed (and 1D), then it represents
56 * the set of integers. That is, the access represents a value that
57 * is equal to the index.
59 * A double is represented as both an (approximate) value "val" and
60 * a string representation "s".
