Upgrade clang? I can't reproduce it with trunk.

Hello, For some reason, I have to stick on llvm 3.3 for a language compiler, I find that the location debug info is attached to each instruction using !dbg, however, I found some of that information is mis-attched and need to be changed, so I want to *know what functions(I checked all funcs in DIBuilder.h but didn't find a appropriate one) are used to attach those !dbg nodes to each

Hello, I'm having this error and couldn't find a resolution from online, any help would be greatly appreciated: clang: /export/home/hzhang86/chapel/chapel-llvm36/chapel/third-party/llvm/llvm/lib/CodeGen/AsmPrinter/DwarfUnit.cpp:839: void llvm::DwarfUnit::addType(llvm::DIE&, llvm::DIType, llvm::dwarf::Attribute): Assertion `Ty && "Trying to add a type that doesn't

>> I have only one real comment -- this violates the contract and spirit of LLVM's metadata design. You're specifically encoding semantics in metadata, but the principle of metadata is that a program with all metadata stripped has the same behavior as one with the metadata still in place. This is a simplified understanding of semantics. As I understand, the expected metadata design

Hi all, I am wondering if someone can give me pointers to how to use the DI* classes defined in DebugInfo.h. In particular, I am confused about how to get a MDNode from the GlobalVariable's that hold the debug info so that they can be passed into the DI* classes, and the difference between MDNode and NamedMDNode in general. Thanks for your help. Alvin

Hello, Do you know where I can find the correct metadata layout in the source code package (which file)? I found a source code that used llvm 2.5 following a slightly different metadata layout as what I read on http://llvm.org/docs/SourceLevelDebugging.html#debugger-intrinsic-functions, which should be compatible with the latest 3.6 version, so where can I check the detailed difference in each

I’m trying to debug SAFECode source code files, and I need to find a way to obtain a GlobalVariable from its appropriate MDNode. How can I do this? I’ve been looking over the doxygen and I can’t seem to find a way to do this. Thanks, Peter Finn

Hello, I found some source code using llvm 2.5 that has a call to Module::getTypeName(Type*), which I can't find it anymore in llvm newer than 3.3, so how can I get the name of a type(e.g a user-defined structure) if we have Type* of that ? Besides, I checked that old llvm maintains a TypeSymbolTable that enabled type name look-up, so what's the replacement and mechanism of it in the

Hello, I'm having this assertion fail when I was using DIBuilder to create the debug information: Expected no forward declarations! !719 The assertion condition is: !isa<MDNodeFwdDecl> (MD) So My questions are: 1. What is exactly the MDNodeFwdDecl ? I saw it's in the latest release 3.6.1, but I also found this link

Hello, I don't know if anyone gets familiar with the llvm Chapel front end, it's version 3.3 and comes within Chapel source package. I'm trying to parse the .bc code generated from a simple helloworld chapel program. Just run a basic Hello pass on the code (default one in the llvm source code) that prints out all the function names in the module. However, it prints a bunch of

Hello, Everyone I'm using llvm 3.6 DIBuilder module to build the debug information for Chapel language(the Chapel-llvm front end works fine). When I run the test program, I got these assertions failed: !718 Expected no forward declarations! !719 Expected no forward declarations! !720 Expected no forward declarations! !721 Expected no forward declarations! !722 All nodes should be resolved!
