search for: pinst

So, you need to bitcast `pinst` to a pointer to Vector of double, since it (I hope for your sake) is a pointer to integer. What you are trying to do is bitcast a pointer into a vector, which probably will lead to an assert or "bad code that doesn't work". -- Mats On 15 April 2015 at 21:57, zhi chen <zchenhn at...

I read the tutorial document, but I didn't understand the it and Ops fields of instruction class well. Can any one give me an example? Instruction *newInstr = new Instruction(Type *ty, unsigned it, Use *Ops, unsigned NumOps, Instruction *InsertBefore); For example, I have an *instruction *pInst *without no the type of operation in advance. If I want to create a new instruction which is similar to the *pInst. *How can I do it? Any help will be appreciated. Thanks.

How can I write code to generate IR for: %2 = bitcast double* %1 to <2 x double>*. %3 = load <2 x double>* %2, align 16 Basically, it is similar to x86 _mm_load_pd1 intrinsics.

Yes. That's what I was the solution in my mind. But I just wanted to know if there was a generic way to save some code...
