Adding intrinsic is not the only way, it is one of the way and user WILL-NOT be required to invoke It specifically. Currently LLVM does not have any instruction to directly represent “sum of elements in a vector” and generate your particular instruction.However, you can do it without intrinsic by...

...struction to my target without using any intrinsics and without adding any new instructions to LLVM. So here is my question: how come I managed to add a new vector instruction without adding an intrinsic and why in order to add this particular instruction (sum elements in a vector) I need to add an insrinsic? Another question that I have is whether compiler will be able to target this new instruction (sum elements in a vector) if it is implemented as an intrinsic or the user will have to specifically invoke an instrinsic. Pardon if questions seem dumb, I'm still learning things. Any help is appr...

My target has an instruction that adds up all elements in the vector and stores the result in a register. I'm trying to implement it in my compiler but I'm not sure even where to start. I did look at other targets, but they don't seem to have anything like it ( I could be wrong. My experience with LLVM is limited, so if I missed it, I'd appreciate if someone could point it out ).
