similar to: LLVM FunctionType cannot be returned as VectorType?

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.

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:

Fantastic! It's working! Thank you so much Craig!!! On Fri, Apr 7, 2017 at 6:05 PM, Craig Topper <craig.topper at gmail.com> wrote: > It should be VectorType::get(Type::getInt32Ty(Context),4).

I am working on AVX2 code generation by LLVM framework. I want to generate LLVM-IR code for the following code by C/C++ API from LLVM framework. I am using LLVM3.8. Basically, I want to generate TARGET (Refer to below) LLVM-IR code for SOURCE function by C/C++ API. As you see below, the AVX2 data type is __m256i which is vector type. How can I indicate vector type (function return type, input

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

I've read up some more on the subject, and it seems the proper way to do this with GCC is g++ and target attributes. I've refactored the patch that way, and it indeed uses SSSE3 automatically on supporting CPUs, regardless of the build host, so this should be ideal both for home builders and distros. Getting the code to build right in c++ mode (checksum_sse2.cpp only) was a bit of an

> What is a `"logically"-widened alwaysinline wrapper for the vector function`? Can you provide an example? Also, what is the `tricky processing` you are referring to that the vectorizer should care about? For the case mentioned earlier: float MyAdd(float* a, int b) { return *a + b; } __declspec(vector_variant(implements(MyAdd(float *a, int b)),
