I've done some investigation and figured out that the crash is caused by a PHINode containing itself. SIAnnotateControlFlow::handleLoopCondition() can't handle such situation - it recurses into itself, calls Phi->eraseFromParent() inside the inner execution, returns into outer one, gets zeroed out object and crashes when trying to do something with its members... f...

Hi all, I wrote code that compiled with llvm 2.8, but now I'm using llvm 2.9 and it doesn't compile anymore: My code looks like this: User *U; ... if (PHINode * phi = dyn_cast<PHINode>(U)) { ... BasicBlock * Pred = phi->getIncomingBlock(I); ... } And when I compile it with clang: Live.cc:130:27: error: member access into incomplete type 'llvm::PHINode' BasicBlock * Pred =...

I guess I didn't have a clear question. Suppose we have BB1 and BB2 both point to BB3. BB1 has variable x. BB2 also as variable x. BB3 will have PHINode for x with 2 value from BB1 and BB2. BB1 BB2 \ / BB3 Now if BB1 and BB2 is extracted into a function (using ExtractCodeRegion), they will be replaced by a basic block called codeRepl (which has a call to the extracted function). codeRepl | BB3 The problem is that the PHIN...

Hi all, I have encountered the following instruction: %.0.i = phi i8* [ %9, %8 ], [ %11, %10 ] How can I get the %8 and %10? I'm using http://llvm.org/doxygen/classllvm_1_1PHINode.html as a reference but I cannot understand how to do that. Thanks -------------- next part -------------- An HTML attachment was scrubbed...

I'm running into an error message about PHINode which I don't understand too well. Hopefully I can explain this clearly. At a high level, I'm just trying to add a fprintf() statement at the end of functions to show me a timestamp. However, I also add an if/then such that I can turn the printing on/off. When using llvm-gcc, I've d...

But in this case, you'll need to do one in-place operand replacement for each successor phi use and call PhiNode::addIncoming for the rest. Note that multiple successor phis may use the same predecessor phi, so you should be careful of mutating the phis w...

Hi, I've been writing an optimization pass (described on the ML previously). Sometimes this pass removes some case entries from switch instructions, which cause an abort because removeCase() doesn't fix the PHINodes predecessors when needed. e.g.: define i32 @foo() nounwind { ifthen: %call = call i32 @bar() switch i32 %call, label %myphi [ i32 0, label %ifelse i32 1, label %ifelse ] ifelse: br label %myphi myphi: %ret.0 = phi i32 [ 0, %ifthen ], [ 1, %ifelse ] ret i32 %ret.0 } Suppose I remov...
