Dear developers: When I am doing basicblock pass, I meet a bug: there is an iterator "I" in a basicblock, and it is not pointing to the first instruction in this basicblock. However, "I--;" will fail by an assertion. The basic block ("I" is pointing to the second instruction) in test.ll: bb: ; preds = %bb1 %1 = call i32 (i8*, ...)* @printf(i8* noalias

Hi all, I am in the process of developing a installer utility for ARM target which can compile any source files to ARM native executable. This installer utility should be present on target itself (whether this is feasible or not?). For achieving this i compiled llvm with clang for target. I copied the binaries to target and when it tried to compile a sample c code i am getting the following

AAAH! I see you are still at 2.5. Then this patch (the fix) is relevant for you: <http://llvm.org/viewvc/llvm-project/llvm/trunk/include/llvm/ADT/ ilist.h?r1=66061&r2=68785&diff_format=h> Cheers, Gabor On 27 Sep., 05:45, hc2... at columbia.edu wrote: > Dear developers: >      When I am doing basicblock pass, I meet a bug: there is an   > iterator "I" in

Hi, Can anyone tell me how to erase an instruction, (specially a load/store instruction) ? If I use Instr->eraseFromParent(), I get following error. Note the instruction does not have any use. opt: /home/chayan/llvm/llvm-2.6/include/llvm/ADT/ilist.h:218: llvm::ilist_iterator<NodeTy>& llvm::ilist_iterator<NodeTy>::operator++() [with NodeTy = llvm::Instruction]: Assertion

Is this the same issue as PR1686? If so, please add to it. What kind of host machine are you using?

I may be mistaken as I just took a quick look, but in ilist_node the function "getPrevNode()" actually calls a method on the previous node: NodeTy *getPrevNode() { NodeTy *Prev = this->getPrev(); // Check for sentinel. if (!Prev->getNext()) return 0; return Prev; } http://llvm.org/docs/doxygen/html/ilist__node_8h_source.html#l00058 Try checking if

I believe this patch has broken a PPC app that I am tracking. Here is a reduced test case. Reproduce with llc -mattr=+Altivec -mcpu=g5. The backtrace looks like this: #0 0x9333ae42 in __kill () #1 0x9333ae34 in kill$UNIX2003 () #2 0x933ad23a in raise () #3 0x933b9679 in abort () #4 0x933ae3db in __assert_rtn () #5 0x0008bd8f in llvm::MVT::getVectorElementType (this=0xbfffdda4) at

Hello John, I was following your procedures and I isolated the problem. The problem are represented by the basic blocks with only one element. for (Function::iterator II = F.begin(), EE = F.end(); II != EE; ++II, ++ii) { BasicBlock* BB=II; if (BB->getTerminator()) { Instruction* current = BB->getTerminator(); Instruction* previous;

Things are still broken. Unfortunately llvm test suite does not contain enough vector code to fully test this. Can you revert the patch first?

Evan: I work on reverting it, although, when I tried yesterday, it wasn't particularly clean (lots of rejected patches, presumably due to intervening commits.) Are you still getting the backtrace or is this just a case of incorrectly generated code? -scooter On Wed, Feb 25, 2009 at 10:09 AM, Evan Cheng <echeng at apple.com> wrote: > Things are still broken.

Hi, all. When I run the llvm using the inline option. I always got the following error message. So I cannot even use inline option. suna14|~/MP1|[37]% opt -inline < scalarize.llvm.bc > /dev/null ../../../include/Support/ilist:104: failed assertion `Traits::getNext(NodePtr) != 0 && "Dereferencing end()!"'

Hi All, I have just started using LLVM . i am facing a issue while using ilist container. Here is a struct with ilist container as its one element. typedef ilist<Instruction *> InstListType; struct list_node { int Impact; InstListType InstList; }; list_node

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?

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)?

I solved by checking if(BB->size()>1) Thank you all for the help ! Now debugging the next segfault.
