Hello, I'm not sure what I am trying to do is possible. I'm trying to create two modules, and call a function in one module from another module. First, a reassurance that I'm not trying to do something completely off the wall would be nice as I don't see any tutorials that do this. Second, any help getting this to work would be wonderful. Thanks, Aaron In my code, you'll

Hi, Can we attach metadata to StructTypes in LLVM IR? If not, is there any other way to add meta information? Thank you -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20180522/46206b08/attachment.html>

If you put a VoidTy as a field of a StructType, you get: /proj/work/llvm/llvm/lib/VMCore/Type.cpp:380: llvm::StructType::StructType(const std::vector<const llvm::Type*, std::allocator<const llvm::Type*> >&): Assertion `Types[i] != Type::VoidTy && "Void type in method prototype!!"' failed. I believe "method prototype" should be "structure

Hi! StructType has no method for adding elements, but I'd like to build a type incrementally, i.e. it starts empty and a global of the type exists. then load instructions are added to a basic block and for each load instruction an element to the type has to be added. Is there a way to do this? For example I could first use UndefValues instead of load and then do a replaceAllUsesWith when the

My apologies if this has already been discussed/explained (reference?). In browsing the new type system implementation, I was wondering if someone could give a simple example of why one would want to reset the name of a previous realized StructType instance (setBody(...) has been called). My curiosity is enhanced by the fact that reseting a name of a StructType instance may result in a symbol

Hi. I have such task: to get information about classes of work program (module) form Module (LLVM class), for example in ModulePass. I tried to analyze source code of LLVM architecture related with Module class, but I have not founded any useful information. Thanks!

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:

I'm building a StructType without a body using StructType *StructType::create(LLVMContext &Context, StringRef Name); and then later adding a body to with setBody(). It starts of isOpaque() == true, and isSized() == false, and after I add the body, isOpaque() == false, but isSized() is still false. If I create a StructType using StructType * StructType ::create(LLVMContext

As of LLVM 3.2, is it possible to use iostream with the MCJIT or interpreter execution engines? I'm getting some errors... Each of these commands correctly prints "hello": echo -e '#include <stdio.h>\nint main(){ printf("hello"); }' | clang -cc1 -emit-llvm-bc -x c++ | lli -use-mcjit echo -e '#include <iostream>\nint main(){ std::cout <<

Hi, how can i correctly calculate the size of a member of a struct (including alignment etc)? This doesn't work : const StructType *STy = cast<StructType>(Ty); for (StructType::element_iterator I = STy->element_begin(), E = STy->element_end(); I != E; ++I) { usigned size =I->get()->getScalarSizeInBits(); //often

Hello, I'm trying to construct a string like "a[1][x].y" in an optimization pass by digging deeper and deeper into a GetElementPtrInst. I can successfully deal with the array/pointer part, but when it comes to the structure field name "y", I cannot figure out how to get anything but the index into the structure. Is there a way to do that, or is this information

Is there a more convenient way to obtain a DIType given a Type than matching up the strings for the names? For example, given: struct S { int x, y; } s; void foo(S *a) { a->x = 0; a->y = 1; } There are DIType nodes for the struct Type: !6 = distinct !DICompositeType(tag: DW_TAG_structure_type, name: "S", file: !3, line: 1, size: 64, flags: DIFlagTypePassByValue,

Hi: We are currently building an internal solution based on LLVM/Clang technologies which involves generating LLVM IR based on Bitcode generated by Clang from C codes. We have a C function which prototype looks like the following: typedef struct { int (*allocFunction)(void* x, void* y); void* YY; } Type4; int bar (Type1 *x, Type2 *y, Type3 *z, Type4 bar) When we compile this code
