Following the discussion on D118229, this marks all pointer-typed kernel arguments as having ABI alignment, per section 6.3.5 of the OpenCL spec: > For arguments to a __kernel function declared to be a pointer to > a data type, the OpenCL compiler can assume that the pointee is > always appropriately aligned as required by the data type.
