Does anyone know how to instrument *double* to <2 x doulbe>**, e.g., 2.2 --> <2.2, 2.2>? For example, I want to change the following IR code %arrayidx1 = getelementptr inbounds [100 x double]* @main.B, i32 0, i32 %i.021 %1 = load double* %arrayidx1, align 4, !tbaa !0 to: %arrayidx1 = getelementptr inbounds [100 x double]* @main.B, i32 0, i32 %i.021 %1 = bitcast double* %arrayidx1

Thanks Nick, that's something what I am trying to implement as the following. But it seems I still only get the constant value not the instruction. Could you please go over the following instruction and see what wrong with it? Thanks for your time again. Value *vecVal = NULL; IRBuilder<> builder(&*pInst); Type *vecTy = VectorType::get(Type::getDoubleTy(ctxt), 2); Value

I got it. Thanks, Nick. So, it is back to the previous problem. If I have the following instruction: %3 = fadd double %1, double %2 I want to change it into %6 = fadd <2 x double> %4, double %5 where %4 = <double %1, double %1>, %5 = <double %2, double %2>, how can I do this?

Hello everybody, What I am trying to do is to create a vector <4 x i32> and save some values to initialize the vector. However, I am using the insertElementInst() and the errors I get are the following; error: within this context Instruction *Insert = new InsertElementInst(instr, emptyVec, index0, "test"); and error: ‘llvm::InsertElementInst::InsertElementInst(llvm::Value*,
