[llvm-dev] How to insert vector type input parameter for function in C/C++ API?
Thank you so much Craig!
I tried it. But still complaining. Here is the error message during
compilation.
HowToUseJIT_SIMD_FuncProto.cpp:94:55: error: expected unqualified-id
VectorType::(Type::getInt32Ty(Context),4),
THIS IS MY CODE:
LLVMContext Context;
std::unique_ptr<Module> Owner =
make_unique<Module>("test", Context);
Module *M = Owner.get();
Function *Add1F
cast<Function>(M->getOrInsertFunction("add1",
VectorType::(Type::getInt32Ty(Context),4),
VectorType::(Type::getInt32Ty(Context),4),
//Type::getInt32Ty(Context), //This is working fine
//Type::getInt32Ty(Context), //This is working fine
nullptr));
Any idea?
Please let me know what is wrong in my code.
Thanks,
Michael

It should be VectorType::get(Type::getInt32Ty(Context),4). You need the word "get" after VectorType:: ~Craig On Fri, Apr 7, 2017 at 6:01 PM, Michael Choi <choimichael103 at gmail.com> wrote:> Thank you so much Craig! > > I tried it. But still complaining.
