4821 | * We basically plug (1) into "map", resulting in a map with "a" | |||
4822 | * in the range instead of "x". The corresponding isl_pw_multi_aff | |||
4823 | * defining "a" is then plugged back into (1) to obtain a definition fro "x". | |||

4827 | * A -> B | |||

4831 | * [A -> B] | |||
4832 | * | |||
4833 | * and define (1) on top of the corresponding space, resulting in "aff". | |||
4834 | * We use this to create an isl_multi_aff that maps the output position "d" | |||
4835 | * from "a" to "x", leaving all other (intput and output) dimensions unchanged. | |||
4836 | * We plug this into the wrapped map, unwrap the result and compute the | |||
4837 | * corresponding isl_pw_multi_aff. | |||
4838 | * The result is an expression | |||
4839 | * | |||
4840 | * A -> T(A) | |||
4841 | * | |||

4843 | * | |||
4844 | * A -> [A -> T(A)] | |||
4845 | * | |||
4846 | * so that we can plug that into "aff", after extending the latter to | |||
4847 | * a mapping | |||
4848 | * | |||
4849 | * [A -> B] -> B' | |||
4850 | * | |||
4851 | * | |||

4853 | * that we do not need to perform any wrapping, and that the result | |||
4854 | * of the recursive call is of the form | |||
