This is one of the few compile-time constant functions with a variable number of arguments, but it's otherwise pretty normal as intrinsics go. $genType atan($genType y, $genType x); $genHType atan($genHType y, $genHType x); $genType atan($genType y_over_x); $genHType atan($genHType y_over_x); Change-Id: Ie852e10f37d73d53f69e806550872bc015f802d6 Bug: skia:12034 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/413439 Reviewed-by: Ethan Nicholas <ethannicholas@google.com> Commit-Queue: Ethan Nicholas <ethannicholas@google.com> Auto-Submit: John Stiles <johnstiles@google.com>
