similar to: [LLVMdev] StructType::setName(...)

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

Background info: http://www.nondot.org/sabre/LLVMNotes/TypeSystemRewrite.txt As I understand it, PATypeHolder, OpaqueType and the Module's TypeSymbolTable are gone. Instead, StructTypes can optionally be

The language I am working on connecting to an llvm back-end (Modula-3) allows a fairly extensive set of recursive declarations. It looks like I can translate all its high-level types using four llvm types that refer to another type: function, struct, pointer, and array. It looks like I can alter an llvm struct type in place after it has been created, using StructType::setBody. I don't see a

Several people on this list have reported issues with the linker regarding a named StructType instance with the same name in two different modules being resolved into two StructTypes with different names due to StructType:: setName(…) collision behavior. Looking at BitcodeReader::ParseTypeTableBody(…), I don't see use of LLVMContextImpl::NamedStructTypes or of Module::getTypeByName(…). Nor do

Hi, I want to add an integer field to all C++ classes in LLVM. Where do I look at in the LLVM source to make the necessary changes? As of now, what I understand is that I need to make changes in Type.cpp (llvm/lib/IR/Type.cpp) where I insert an integer field in the ArrayRef passed to StructType::setBody?

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 implementing c style "sizeof()", and I did as http://nondot.org/sabre/LLVMNotes/SizeOf-OffsetOf-VariableSizedStructs.txt illuarstrated, and it works find, here's an example of my implementation: auto *p = builder.CreateGEP(structTy, llvm::ConstantPointerNull::get(pointerTy), constint1); auto *size =

> 1. Clang - Jay, do you have a patch for this?  Can you create a branch of the clang repo or send an updated version of the patch to the list? I've created a clang type-system-rewrite branch and committed all my purely mechanical changes: de-constifying llvm::Types as necessary, and using the new llvm::StructType::createNamed/setBody to create the "implicit" structs used by

With StructType you can create an empty structure and then call setBody later. How can one do the same thing with a PointerType? I'm translating a recursive structure which includes pointers to itself. I end up creating multiple copies of logically equivalent pointer types. -- edA-qa mort-ora-y -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Sign: Please digitally

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

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 Chris, > 3. Clang/dragonegg need to adapt to the new API (help appreciated!) what needs to be done exactly? Ciao, Duncan.

Hi, I'm having a play with LLVM to implement a custom language (for my intellectual curiosity only). I'm wondering how, when using IRBuilder, one can can it to emit a recursive type definition? The code for TypeBuilder explicitly states that it doesn't handle recursive types... I'm after being able to emit, programmatically, stuff like the Named Types example in the Language

I tried to compare two types. Because of renaming, the comparison result is not as expected. How to deal with renaming while comparing types?

Hi Mehdi, Thanks for your reply. It seems caused by random rename because I saw %struct.StructTyName.692.475*, which might be twice renaming. Does this collision occur because this type is declared more than once? I encountered this problem when used clang to compile transmission 1.42 (http://download.transmissionbt.com/files/) with configuration: "./configure --disable-gtk". Then

Hi, everyone. I've run into a strange problem generating code that contains the `dispatch_object_t` type. The problem happens when a program does these steps (all with the global LLVMContext): 1. Loads a module (otherModule) that uses `dispatch_object_t`. 2. Generates code that calls `dispatch_release`, which takes a `dispatch_object_t` argument, into a module (mainModule). 3. Links
