I'm trying to generate the declarations for function intrinsics, and I must be misunderstanding how to create new functions - I saw that a function with no basic blocks is treated as a declaration, so I tried to just create one and add it to the globals list: llvm_type *structTy, *ptrToStructTy; structTy = llvm_type_create_struct(0, 0); structTy =

Thanks for the information I am trying to use one of your examples for recursive data structures: ========================= PATypeHolder StructTy = OpaqueType::get(); std::vector<const Type*> Elts; Elts.push_back(PointerType::get(StructTy)); Elts.push_back(PointerType::get(Type::SByteTy)); StructType *NewSTy = StructType::get(Elts); // At this point, NewSTy = "{ opaque*, sbyte*

I'd like to be able to make use of a structure type and its fields before it is completely defined. To be specific, let me ask detailed questions at various stages in the construction of a recursive type. I copy from http://llvm.org/docs/ProgrammersManual.html#TypeResolve // Create the initial outer struct PATypeHolder StructTy = OpaqueType::get(); Is it possible to declare

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'm trying to run the example of recursive type construction examples in LLVM Programmer's Manual, here is the code: // Create the initial outer struct PATypeHolder StructTy = OpaqueType::get(); std::vector<const Type*> Elts; Elts.push_back(PointerType::get(StructTy)); Elts.push_back(Type::Int32Ty); StructType *NewSTy = StructType::get(Elts); // At this point, NewSTy =

As far as I can tell, when you construct a type using the support library StructType::get, you have to pass in a list of types. How can you make a Recursive type by passing in a pointer to the type you are constucting. An example where something really simple like the line below was output would be perfect. %struct.linked_list = type { %struct.linked_list*, %sbyte* } Thanks for any help,

Hello all, I am willing to do "eliminating the void type" project. Is there anyone working on it? === Overview === The general concept is to replaced void with {}. And 'ret void' is a synonym of 'ret {} {}.' === Further Implementation Details === 1. Deleting VoidTyID 2. Deleting LLVMVoidTypeKind (one-to-one relation between VoidTyID and LLVMVoidTypeKind) 3. Use

Hi Mitnick, > === Overview === > > The general concept is to replaced void with {}. And 'ret void' is a synonym of > 'ret {} {}.' in a sense the concept is just to delete void and not to replace it with anything in particular. Of course front-ends (clang, dragonegg) need to produce something instead of void, and {} is an example of what they might produce, but they

Hi, Given these C instructions: ============================== struct stru { struct stru *Next; }; struct list *NewStru = malloc ( sizeof ( struct stru ) ); struct list *tmp.3; ... tmp.3 = NewStru->Next; ============================== LLVM generates something like this: %tmp.0 = malloc %struct.stru ; <%struct.stru*> %tmp.3 = getelementptr %struct.stru* %tmp.0, int 0, uint 1 ;

I don't know if the toy program in chapter 4 of the tutorial implementing Kaleidoscope in llvm with C++ is part of your regression suite, but with the version of llvm I installed last weekend, it does not compile: hendrik at lovesong:~/dv/llvm/tut$ g++ -g toy.cpp `llvm-config --cppflags --ldflags --libs core jit native` -O3 -o toy toy.cpp: In member function ‘virtual llvm::Value*

I agree that the ArrayRef is likely the issue. I've debugged a crash caused by a temporary ArrayRef like that a couple times. Either do what David suggested or use a normal array: Metadata *mdArray[] = {ConstantInt::get(Int64Ty, 0), newMD}; ~Craig On Thu, Apr 30, 2020 at 9:56 AM David Blaikie via llvm-dev < llvm-dev at lists.llvm.org> wrote: > > > On Thu, Apr 30, 2020 at

Hello, I am editing the LowerTypeTests pass in LLVM, and part of my additions include the following 3 lines of code: // newTypeName is a std::string MDString* newMD = MDString::get(M.getContext(), newTypeName); ArrayRef<Metadata*> mdArray {ConstantInt::get(Int64Ty, 0), newMD}; auto* node = MDTuple::get(M.getContext(), mdArray); Thus far, I have been developing on a version of Clang with
