[LLVMdev] Modeling GPU vector registers, again (with my implementation)
...eems to me that LLVM sub-register is not for the following hardware architecture. All instructions of a hardware are vector instructions. All registers contains 4 32-bit FP sub-registers. They are called r0.x, r0.y, r0.z, r0.w. Most instructions write more than one elements in this way: mul r0.xyw, r1, r2 add r0.z, r3, r4 sub r5, r0, r1 Notice that the four elements of r0 are written by two different instructions. My question is how should I model these sub-registers. If I treat each component as a register, and do the register allocation individually, it seems very difficult to merge...

[LLVMdev] Do I need to add new intrinsic functions for the OpenGL shading language swizzle?
...lare vector types: void main() { vec4 a; vec3 b; vec2 c; } You can access the element of vector by using .xyzw, it means the 1st, 2nd, 3rd, 4th element of the vector are x, y, z, w. Ex: void main() { float f; vec4 a = vec4(1.0, 2.0, 3.0, 4.0); vec4 b = vec4(3.0, 4.0, 5.0, 6.0); v4.xyw = vec2(2.5, 3.3. 7.7); f = v4.y; b.xy += a.xy; } Because my chip supports this facility in instruction & register level, I think I have to preserve the semantic of this 'vector' and 'swizzle'. I don't think this GLSL::vector can be represented directly by the llvm::vec...
