This one is structured a bit differently; it gets to length() value, then divides the input by its length using a bit of DSL. Since all the inputs are constant, the constant-folder will do the right thing. $genType normalize($genType x); $genHType normalize($genHType x); Change-Id: I51e5c65fa9e33738cbe253fcc97ee2160c48cfdd Bug: skia:12034 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/412340 Commit-Queue: John Stiles <johnstiles@google.com> Auto-Submit: John Stiles <johnstiles@google.com> Reviewed-by: Brian Osman <brianosman@google.com>
