[LLVMdev] inserting a target specific builtin in llvm pass

[Zhao, Weiming]

You can do like this:
Function *MyFunc = Intrinsic::getDeclaration(M, Intrinsic::my_instrinc);
CallInst::Create(Myfunc, Args, "", InsertBefore);

Subject: [LLVMdev] inserting a target specific builtin in llvm pass

Hi,

I'm writing a pass which needs to insert an intrinsic in for my target, but I'm not sure how to create the call. I've tried defining a function, with the target intrinsic as its name, and then creating a new CallInst to call it. But how am I supposed to declare this function as an intrinsic?

Thanks,

Sam
