In this chapter, we present a thorough evaluation of our Whole-Function Vectorization implementation in various scenarios: First, in
WFVOpenCL
, a prototypical OpenCL CPU driver that was implemented to showcase the benefits of WFV for a data-parallel language [Karrenberg & Hack 2012]. Second, in
AnySL
, a shading system aimed at highly efficient code without loss of portability and flexibility [Karrenberg et al. 2010]. Third, in
Noise
, a compiler that allows the user to specify which optimizations should be run on what parts of the code. In addition, we quantify the impact of the key techniques that exploit the results of the analyses described in Chapter 5.
