I am using LLVM C++ API to generate IR for some structure data. For example: struct mystruct {int a:1; int b:2; unsigned long c} = {{1, 2, 3}}; I read the document and tried the demo cgi, it seems the API requires user to handle padding and value combination for the initializer by themselves. Is there any way to create the struct more simply like this:

Dear all, I am using LLVM C++ API to generate some code. In particular, I am dealing with AVX2 SIMD API which uses __m256i. My function input types a set of vectors and return type is also a vector. /////////////////////////////////////////////////////////////////////////////////////////// arguments.push_back(VectorType::get(IntegerType::getIntNTy(TheContext, 64), 4));//int64*4 = __m256i

Hi Stefan, Thank you very much for answering my question! I followed your suggestion but the function still cannot return the correct result. I also set target-feature attributes for my function. I am using LLVM 6.0. It only prints out some random large numbers but the correct answer is supposed to be all 0. Can you please help me figure out what's going on here? Any help will be greatly

Hi Joshua, Thanks for your great comment. I made up a ConstantVector in IR. Then I successfully use AVX intrinsics to retrieve the returned vector data. The remaining thing is that how to pass the vectors to LLVM function using intrinsics. Do you have any suggestions? Please forgive me if the question is too naive. I pasted below two IR I used. The first one works. The second one doesn't.
