Could anyone please elaborate it? http://llvm.cs.uiuc.edu/ChrisLLVM/docs/CodeGenerator.html#selectiondag_legalize "Instead of using a Legalize pass, we could require that every target-specific selector supports and expands every operator and type even if they are not supported and may require many instructions to implement (in fact, this is the approach taken...

...entation is out of date and doesn't make a ton of sense for your application. I would suggest that you implement it in the context of the SelectionDAG framework that all of the code generators either currently use or are moving to. I updated the documentation here: http://llvm.cs.uiuc.edu/ChrisLLVM/docs/ExtendingLLVM.html#intrinsic This will allow you to do something like this: %i32v4 = type <4 x uint> %f32v4 = type <4 x float> declare %f32v4 %swizzle(%f32v4 %In, %i32v4 %Form) %G = external global %f32v4 void %test() { %A = load %f32v4* %G %B = call %f32v4...
