...t to the basic block which has a method to get to the Funciton. In both cases, the method is called getParent(). Once you get the Function, you can find all the internal uses using the use chain from the Function. > > Start looking at the user class here: > > http://llvm.org/doxygen/classllvm_1_1User.html > > When you go through the user chain, you will find all sorts of instructions and possibly other things. If you find anything other than a call Instruction, you have hit upon a case that's more difficult to handle (related to using function pointer). If you run whatever analys...

Hi, I'm having a problem with the use iterator. Each "use" that I see, when using the use_iterator, is the same as the "def". Meaning, in the code below the pDef is always equal to pUse pointer for every instruction in all basic blocks (except terminators). for (auto i = inst_begin(f), ie = inst_end(f); i != ie; ++i) Instruction* pDef =

Hello everybody. I'm quite new to LLVM and I'm encontering problems with cloning basic blocks. My two basic blocks are in the same function and it doesn't really matter how the cloned one behave for the moment. Of course, to do so, I used the cloning.h 's method "CloneBasicBlock" but I have the "Instruction does not dominate all uses!" error. I know what it

Thanks Duncan, Yes, it is a ConstantExpr! Thank you! Now trying to find a clue in ConstantExpr's functions to get that string :-) Regards, Welson On Thu, Jan 26, 2012 at 9:04 PM, Duncan Sands <baldrick at free.fr> wrote: > Hi Welson Sun, > > > Hi, if I have some LLVM code like this: > > > > @.str = private unnamed_addr constant [7 x i8]
