Hi Devang, Before I get to the contents of this particular patch, I have a higher-level design question. Why is metadata stored off the LLVMContext? That seems like the wrong place to me, this data is all specific to the particular module. Specifically, a single MDNode may not cross modules, and if a module is destroyed we should eliminate all the metadata that came with it. So, why

Hi, I'm trying to recover the inheritance relations for a class type (so a list of base classes) from a llvm ir file generated via compiling some cpp file using clang. I have access to the TypeSymbolTable and have found the class type I want to know the base classes for in the table. How do I go about extracting this (debug) information? I'm stuck here: if(StructType*

Hello LLVM Community, I'm working on some analyzer\checker and want to implement checker for variables. In that case, I want to retrieve some information about types of variables or identify that the variable is either string or not. As an example, for strings which can be char or string type I came up with a solution to find it out via isString or isCString methods. But for strings whose

I'll ask again that question. Thank you Adrian, I've looked through IR Verifier and it helps me to understand some parts of retrieving metadata and debug info. But , after that, I've faced with another problem: Original Code: std::wcout << L"WCHAR_HELLOWORLD" << std::endl;b IR Code: @.str.2 = private unnamed_addr constant [17 x i32] [i32 87, i32 67, i32 72,

Bugs 1519 and 1521 currently prevent a clean bootstrap on Linux x86_64. I was able to hack it to work :-) The attached patch includes two parts. One is a tentative fix bug 1519: just set LastFieldStartsAtNonByteBoundry in allFieldsAreNotBitFields. The other one is a plain hack. llvm-gcc and gcc disagree on how to pass some structures, so stage2 gcc fails to use the libcpp compiled by gcc. So I

Hello everyone, I want to pass a set of integers using metadata but I don't know how. I have tried: the integers are in array[] *1. * LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } *is->setMetadata("path",MDNode::get(C,values));* failes when setMetadata(),

Hi All, In LTO, we load in the source modules and link the source modules into a destination module. Lots of MDNodes are only used by the source modules, for example Xalan used 649MB for MDNodes after loading and linking, but the actual destination module only has 393MB of MDNodes. There are 649-393MB (40% of 649MB) not used. MDNodes belong to the Context, deleting modules will not release the

Hello everyone, I have an integer and I want to convert it to StringRef in order to set metadata. setMetadata->(StringRef, MDNode*); It is there a native LLVM way to do it? 1. In the llvm::APSInt Class is toString() method, which seems it is not for this purpose 2. itoa and string are not part of LLVM 3. stringstream is not part of LLVM 4. to_string is not part of LLVM 5. any casting method?
