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 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 %'

ValGrind gives me some info, but I'm not great at memory stuff, and so I'm not sure what to make of it... This is code that worked for someone 8 months ago, and I'm just trying to get it to run on llvm 2.9 instead of 2.8, so the fact that it hasn't been working is frustrating. Anyway, my issues seem to stem from IntervalIterator, as seen below. I have a lot of similar issues

Hello: I recently attempted to update the ARM cross-compilation setup I had with llvm, and it did not work, so I wanted to revert back to my initial configuration. I reconfigured/make/make install'ed my llvm which executed fine, and then cleared out my llvm-gcc obj and install folders, and reconfigured gcc from within llvm-gcc/obj as follows: ../llvm-gcc-4.2-2.9.source/configure

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

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.

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

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.

Hello all: I apologize for what I imagine is a rather silly question, but I'm still somewhat new to LLVM and am stuck. I am reworking some code that was originally in the backend involving MachineInstructions and MachineOperands, and I now need for it to function as an LLVM IR pass, using just Instructions, etc, and nothing related to 'Machine'. However, I am not sure how to get the

Hello, I am working on an LLVM pass which, among other things, selectively duplicates instructions in a program. This results in a few new instructions added to the final IR to facilitate checking, and I'd like to annotate the generated code file with a comment or something like it that would indicate that a given specific instruction has some certain property. Essentially, just printing

Hi Pablo, Can you provide a link to the document containing a reference to llvm::StringStream? I've looked in both the llvm coding standards, and llvm programming manual for versions: ToT (3.0), 2.9 (which seems to be the same as ToT), and 2.8. Obviously my search is missing something.

http://llvm.org/releases/2.0/docs/CodingStandards.html I just realized that the target version is LLVM 2.0, so most likely the llvm::StringStream is deprecated by now. Thanks for your response!

Hi, I need to convert an integer into a string. I would normally do that in C++ by using the StringStream class, but the LLVM coding standards discourage using that class. The same coding standards suggest to use llvm:StringStream instead, but I cannot find that class anywhere; furthermore, the header file where it was supposed to be (according to the coding standards) doesn't even exist. Is

Hello, I'm working with a pass that operates at the LLVM IR level. I need to run some statistics on instructions that access memory, and I'm wondering, at the IR level, which instructions aside from Load and Store access memory directly as a result of their operation? I know on an ISA level, this varies from arch to arch, but I'm wondering how LLVM has this set up at the IR level.
