...39;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>

In that case, you want to put all of the registers in one register file, and not make the constant register allocatable (e.g. see X86RegisterInfo.td, and note how the register classes include EBP and ESP, b...

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 :
