Hi, Thank you guys for helping me out with my previous questions. I am new to LLVM, and I'm getting stuck trying to do some basic stuff: Currently, I'm trying to move all the basic blocks of one function into another one, and at some point insert a branch into the moved function's entry point. The best way which I've found is to use CloneBasicBlock (from Cloning.h). However, I

Hi. I would like to move first function of module to end. To do this, I remove function from module, then I insert it with getOrInsertFunction() method. It worked. But there is a problem: I can't see body of function (basic blocks). In other words, function basic blocks don't move. To solve, I store function basic blocks before remove it. and after function insertion, I want to insert

The if you are cloning into the same LLVM module the CU should not cloned. If don't mind sharing your code, I can try to help diagnose why the CU gets cloned... just send me a patch that applies to trunk and instructions. -- adrian > On Jun 16, 2017, at 1:54 PM, Sergei Larin <slarin at codeaurora.org> wrote: > > Sorry… It takes a pass that was not accepted for upstreaming….
