Allow derivatives in Runtime Effects when ES3 restrictions are off. We can now add functions to sksl_public.sksl with an $es3 prefix. These will be allowed in a Runtime Effect when strict-ES2 mode is disabled. Note that the CPU backend still doesn't have support for these calls, and will fail ungracefully (assertion, nonsense result) if these intrinsics are used. The testing here is limited, due to an unrelated bug in SPIR-V (skia:12340) Change-Id: I9c911bc2b77f5051e80844607e7fd08ad386ee56 Bug: skia:12202, skia:12340 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/439058 Commit-Queue: John Stiles <johnstiles@google.com> Reviewed-by: Ethan Nicholas <ethannicholas@google.com> 2021-08-13 15:43:21 +00:00			`float2 dx(float2 coords) { return dFdx(coords); }`

Add SkSL error tests for runtime_errors directory. This enables the SkSL error testing logic for runtime effects. The core logic is identical, only the ProgramKind differs. (Error creation scripts: http://go/paste/6413797460803584 with some light post-processing) Change-Id: I877205b3cc1014b50ccccf6037a2f4034c07543e Bug: skia:12665 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/506538 Reviewed-by: Brian Osman <brianosman@google.com> Commit-Queue: John Stiles <johnstiles@google.com> Auto-Submit: John Stiles <johnstiles@google.com> 2022-02-09 21:06:46 +00:00
