I think I understood that, but what I mean is what is the function responsible to do mapping is it MapValue() in ValueMapper.h?

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?

What do you mean by mapping to integers?

...e list head. I don't see any method like hasPrevNode. It can be a weird problem because "current->getPrevNode()" is indicating to "current" itself (the problem appears for the BB with only one element)?

Hello, Thank you for your answer. If I want to use then I have error: ‘NodeTy* llvm::ilist_half_node<NodeTy>::getPrev() [with NodeTy = llvm::Instruction]’ is protected error: ‘llvm::ilist_half_node<llvm::Instruction>’ is not an accessible base of ‘llvm::Instruction’ Do you know any other method to access the previous instruction of a terminator instruction?

Hello, I followed the http://stackoverflow.com/questions/13852180/how-to-get-variable-definition-line-number-etc-using-dbg-metadatain order to get the line number definition for local variables (allocas), which works fine. But I need the same for globals. So I tried to hack the `findDbgGlobalDeclare()` method from http://llvm.org/docs/doxygen/html/DbgInfoPrinter_8cpp_source.html#l00062 . However,

Hi, I solved it. From the ConstantStruct you can call getOperand() multiple times, so "mine" as deep as you can.

...he end, I just want to apply a DFS on a CFG of a function. And I need oriented edges and wanted to use MachineBasicBlock::const_succ_iterator. It is there a way to get the CFG with oriented edges by using a FunctionPass? Thank you !

...u use the incorrect one for simple types, you may not notice it. The error you have seems to me like a memory corruption because you went out of bound and corrupted the memory somewhere, Valgrind may help you figure out what is going on.

HI, I am creating a pass that will pass loaded value by load instruction to an external function. I don't know how to do it.Please Help.

Hello everyone, I have written several complex passes till now, but I cannot write a MachineFunctionPass pass. It just gives me segfault. Hence I reduced the pass to the following form : using namespace llvm; namespace { class CFGexplorator : public MachineFunctionPass { public: static char ID; // Pass identification, replacement for typeid CFGexplorator() : MachineFunctionPass(ID)
