Dear All, I am unable to complete the R code for deleting nodes in a binary search tree. Have provided the code snippet below for an usecase where the node to be deleted would have a leftnode and no rightnode. I am stuck up at how to release the node pertaining to the key value given by the function call and then assigning the leftnode in place of the deleted note. Any help would be appreciated

Is this piece of code in DAGCombiner::visitLOAD removing a dead node? 06155 if (N->use_empty()) { 06156 removeFromWorkList(N); 06157 DAG.DeleteNode(N); 06158 } If it is, is there a reason it doesn't push its operands to the work list as done in line 974-975? 00970 // If N has no uses, it is dead. Make sure to revisit all N's operands once

Hey everyone, So I have an LLVM pass that appears to run completely and work fine, and then it aborts at the very end. When exiting the final runOnFunction call, I get the following error / stack dump. I cannot figure out why this is happening for the life of me - does anyone have any ideas? I'm not trying to do any crazy deallocation or anything, it just seems like a normal pass to me.

Hi Griffin, did your pass create a data structure that holds values somehow, and forgot to delete it? Also, try running under valgrind in case this is due to a memory error of some kind. Ciao, Duncan. > So I have an LLVM pass that appears to run completely and work fine, and > then it aborts at the very end. When exiting the final runOnFunction call, > I get the following error /

Our domain controllers have run samba 4.4.3 since it was released. We didn't upgrade because it was so stable :) I recently decided that release was too old and upgraded to 4.8.2 (then current). Our domain controllers were crashing on 4.8.2 so I upgraded to 4.8.3 as soon as it was released but this has not resolved the issue. When the issue occurs the DC becomes unresponsive and needs to be

Using Valgrind hasn't shown me anything terribly unusual. And I'm confused because its not even trying to delete a real instruction; deleting a void type with no name? That doesn't make any sense... Any other hints? I've seen a few posts in the past about this relating to some internal LLVM bugs... -Griffin On Thu, 12 Jan 2012 21:26:41 +0100, Duncan Sands <baldrick at

Yes, it is a pass. Here is a very general overview of the file structure as far as the AA is concerned. LLVM is not my strong-suit, I do hardware simulators, not compilers. using namespace llvm; char RelRecovery::ID = 0; static RegisterPass<RelRecovery> X("relRecovery", "Reliability transformation for lightweight recovery"); void

Hello all, I am working with someone else's LLVM code, which is about 8 months old. Part of this pass involves AliasAnalysis, and I'm getting the above assertion when the pass completes. The dump is as follows: -------------------------------- Program received signal SIGABRT, Aborted. 0xf7fdf430 in __kernel_vsyscall () (gdb) bt #0 0xf7fdf430 in __kernel_vsyscall () #1 0xf602e921 in

Hello all, I really, really, really need your help. This is my third email now, please don't ignore me! I understand this must be a trivial thing, but I've ground to a halt, and REALLY need some guidance. Please see below for the context of my problem. I'm not trying to be a waste of time, but I'm desperate here. I have a getAnalysisUsage method which does the following

Hello, I've been stuck with a problem for about a month, and it has stumped everyone in my lab. I have a function pass that runs, and when it finishes and opt goes to return, I get: While deleting: void % An asserting value handle still pointed to this value! UNREACHABLE executed at /x/grwright/llvm/llvm-2.9/lib/VMCore/Value.cpp:569! On a simple test case, the error becomes 'i32 %'

My allocator failed on MultiSource/Applications/Burg test. I run bugpoint and it

I have ran under valgrind memcheck the process using libLLVM-2.9.so (rev.126022) and got several errors: ==24227== Invalid read of size 1 ==24227== at 0x40274C9: memcpy (mc_replace_strmem.c:497) ==24227== by 0x40D5B84: char* std::string::_S_construct<char const*>(char const*, char const*, std::allocator<char> const&, std::forward_iterator_tag) (in

I'm working on a pass (both LLVM and the pass have been compiled in debug+asserts mode) but when the pass crashes in the stack trace printed by opt the names of the functions inside my pass don't appear (see frames 14-16).

I recently upgraded from llvm 3.7.1 to a pre release of llvm (3.8.0rc2) in order to test some issues regarding bug 24233. After upgrading I starting to see heap corruption messages in vs 2015 sp1 when my program exits. "HEAP[ConsoleEngine.exe]: Invalid address specified to RtlValidateHeap( 0000000000290000, 0000000000318698 )" Initially I only got it in Release build. Debug build seems
