...constant (e.g. returns > 1.0)? Otherwise, how can it be a useful value? Yes, it's a constant register. Because the instruction cannot contain an immediate value, a constant value may be stored in a constant register, and it's defined _before_ the program starts by API. For example: SetConstantValue( 5, Vector4( 1, 2, 3, 4 ); // C5 = <1,2,3,4> HANDLE handle = LoadCodeFromFile( filename ); SetCode( handle ); // C5 is referenced here Execute(); -- Tzu-Chien Chiu, 3D Graphics Hardware Enginner, <URL:http://www.csie.nctu.edu.tw/~jwchiu>

All registers in my hardware are 4-element vector registers (128-bit). Some are floating point registers, and the others are integer registers. I typedef two packed classes: [4 x float] and [4 x int], and add an enum 'packed' to MVT::ValueType (ValuesTypes.h). I declared all 'RegisterClass'es to be 'packed' (first argument of RegisterClass): def GeneralPurposeRC :
