//
// High Level Goals
//
// - Serve as the runtime/DDI representation for all D3D11 tokenized code,
//   for all classes of programs, including pixel program, vertex program,
//   geometry program, etc.
//
// - Any information that HLSL needs to give to drivers is encoded in
//   this token format in some form.
//
// - Enable common tools and source code for managing all tokenizable
//   program formats.
//
// - Support extensible token definitions, allowing full customizations for
//   specific program classes, while maintaining general conventions for all
//   program models.
//
// - Binary backwards compatible with D3D10.  Any token name that was originally
//   defined with "D3D10" in it is unchanged; D3D11 only adds new tokens.
//
// ----------------------------------------------------------------------------
//
// Low Level Feature Summary
//
// - DWORD based tokens always, for simplicity
// - Opcode token is generally a single DWORD, though there is a bit indicating
//   if extended information (extra DWORD(s)) are present
// - Operand tokens are a completely self contained, extensible format,
//   with scalar and 4-vector data types as first class citizens, but
//   allowance for extension to n-component vectors.
// - Initial operand token identifies register type, register file
//   structure/dimensionality and mode of indexing for each dimension,
//   and choice of component selection mechanism (i.e. mask vs. swizzle etc).
// - Optional additional extended operand tokens can defined things like
//   modifiers (which are not needed by default).
// - Operand's immediate index value(s), if needed, appear as subsequent DWORD
//   values, and if relative addressing is specified, an additional completely
//   self contained operand definition appears nested in the token sequence.
