Avoiding during my pass the optimization (copy propagation) of my LLVM IR code (at generation)
...LLVM IR.
To my surprise the following LLVM pass code generates optimized code - it does copy
propagation on it.
Value *vecShuffleOnePtr = Builder.CreateGEP(ptr_B, vecShuffleOne, "VectorGep");
...
packed_gather_params.push_back(vecShuffleOnePtr);
CallInst *callGather = Builder.CreateCall(func_llvm_masked_gather_v128i16,
packed_gather_params);
callGather->addAttribute(AttributeSet::FunctionIndex, Attribute::NoUnwind);

It does *constant* propagation to be exact.
