Looking at the breaking change: +// On ARM we expect that you're using Clang if you want SkJumper to be fast. +// If you are, the baseline float stages will use NEON, and lowp stages will +// also be available. (If somehow you're building for ARM not using Clang, +// you'll get scalar baseline stages and no lowp support.) Well clearly the fallback was not tested.
