16 /* A helper class for inlining a pet_tree of the body of a called function.
17 * It keeps track of the substitutions that need to be performed on
18 * the inlined tree, along with the assignments that need to performed
19 * before the inlined tree.
21 * In particular, for a scalar argument declared "n" in the callee
22 * and passed the expression "e" by the caller, an assignment
24 * n' = e;
26 * is added before the inlined tree and n is replaced by n' in the inlined
27 * tree. n' may have the same name as n, but it may also be different if
28 * n also appears in the caller.
29 * For an array argument declared "a" in the callee and passed
30 * the expression "X[i1,...,in]" by the caller, assignments
32 * __pet_arg_1 = i1;
33 * ...
34 * __pet_arg_n = in;
36 * are added before the inlined tree and "a" is replaced by
37 * X[__pet_arg_1,...,__pet_arg_n] in the inlined tree.
39 * The assignments are stored in "assignments".
40 * The substitutions are stored in the superclass.
