I also notice that we call `internal::GreaterThanBitmap` for each 64 levels, which always goes through the dynamic dispatch indirection (meaning two function calls, I think). We could call `GreaterThanBitmapImpl` but that requires compiling a specialized version of `level_conversion_inc.h` for AVX2, otherwise we lose performance. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
