8.1.3 Loop Table (L)

The loop table is printed after each program unit (function) and shows what KAP did with each for loop in the function. If the loop could not be optimized, a reason is given. The loop table is the primary listing tool for understanding what KAP did with the program.

The line messages are summaries of KAP actions for each loop (both loops in the original source code and loops which KAP generated). The loop to which each refers can be identified from the main loop table. The abbreviations used are explained after the main table.
