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

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 I see this use anywhere else in BitcodeReader's implementation (.cpp file). D...

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,

Currently, Structure layout is left to targets, which implement them according to the ABI of that platform. While this is fine for most structures, it makes packed structures very ugly. All fields in a packed type must be converted to byte arrays with casts to access fields, which bloats accesses and obsfucates the types. First class support for packed types would clean up the generated code

OK here's a new version of the patch - and the unions.ll test actually passes :) On Mon, Jan 18, 2010 at 1:40 PM, Chris Lattner <clattner at apple.com> wrote: > > On Jan 16, 2010, at 11:15 AM, Talin wrote: > > OK here's the patch for real this time :) >> >> On Fri, Jan 15, 2010 at 4:36 PM, Talin <viridia at gmail.com> wrote: >> Here's a work

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

By any chance, is there also a way (short of iterating on all instructions and globals) to find all "uses" of a structtype? -------------- next part -------------- A non-text attachment was sc...

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,

I've made all the suggested changes - however, I'm having a bit of problem running the tests. I started "make check" and several hours later it had only made it through about 1/3 of the tests. I'm not sure what the deal is. On Mon, Jan 18, 2010 at 1:40 PM, Chris Lattner <clattner at apple.com> wrote: > > On Jan 16, 2010, at 11:15 AM, Talin wrote: > > OK

Dear All, I’m working on a project that extends C. I’m adding a new type of pointer that is a fat pointer. It has some metadata about the pointed object besides the starting address of the object. Currently I implemented this pointer as an llvm:StructType. In llvm::Type generation function llvm::Type *CodeGenTypes::ConvertType(QualType T) in the case for clang::Type::Pointer, instead of creating
