Compilation Methods SS 2011 - Slide 506d
Objectives:
Loop carried dependences
In the lecture:
Explain loop carried dependences
- the 4 kinds,
- they occur, because a new value is stored in the same register on every iteration,
- they are relevant, because we are going to merge operations of several iterations.
Questions:
- Explain why loops with arrays can have dependences into later iterations that are not the next one. Give an example.
