similar to: [LLVMdev] Cannot get Alias Analysis?

Hi, How can I use profile information into my pass for performing some analysis. I tried something like: PassManager PassMgr = PassManager(); cl::opt<std::string> ProfileDataFile(cl::Positional, cl::desc("<llvmprof.out file>"), cl::Optional, cl::init("llvmprof.out")); PassMgr.add(createProfileLoaderPass(ProfileDataFile));

The following code is causing an "UNREACHABLE executed!" and a stack dump, any ideas? namespace { struct myPass : public CallGraphSCCPass { static char ID; myPass() : CallGraphSCCPass(ID) {} virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesAll(); AU.addRequired<LoopInfo>(); } virtual bool runOnSCC(CallGraphSCC &SCC)

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I try to write a tool that uses the PassManager to load profiling information for a module like this: ... ModulePass *LoaderPass = createProfileLoaderPass(); PassMgr.add(LoaderPass); PassMgr.run(*M); ... I can verify that the pass was run, but how to I get to the ProfileInfo implemented by that pass? I tried ... ProfileInfo PI =

I'm building a SCCPass below, it appears that the CallGraphNode->getFunction returns a valid function but seg faults on call like "getName" or "size" but not on calls like "empty" (which returns false). My understanding is that the heirarchy is: CallGraphSCC->CallGraphNode->Function->BasicBlock->Instruction, is this not the case? virtual bool

Hi, List, As you may know, BCC of android makes use of LLVM's major components. Its LTO actually selects some optimizations of LLVM. I found it can not only use "-functionattrs". I must first use -argpromotion first, or I end up this error: Pass 'Deduce function attributes' is not initialized. Verify if there is a pass dependency cycle. Required Passes: bcc:

I have not made a separate pass. I have done it in single pass ie added ProfileLoaderPass , got information in PI and now I am planning to perform the analysis here itself. I was trying to print information using ProfileInfoPrinter pass but was unable to do it. namespace { class MyAna : public ModulePass { ProfileInfo *PI; public: static char ID; // Class identification, replacement

In addition to the link below, please check for functions like "llvm.debug.declare", "llvm.debug.value", as you will not get LoopInfo for these.   Pankaj   ________________________________ From: Devang Patel <dpatel at apple.com> To: Ryan Taylor <ryta1203 at gmail.com> Cc: llvmdev at cs.uiuc.edu Sent: Wednesday, November 30, 2011 11:08 PM Subject: Re: [LLVMdev]

Thanks for the info. Curious, do you know if there is an opt that will put all loops, including nested ones, in functions (ie each loop in it's own function)? What I'm trying to do is create a way for each loop to have only one exit. I want all loops to be single exit loops? I can write my own pass but I'd rather not. I think that if I can put each loop into it's own function

We can't simply free the connector after calling drm_connector_init on it. We need to clean up the drm side first. It might not fix all regressions from 2b5d1c29f6c4 ("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"), but at least it fixes a memory corruption in error handling related to that commit.

Hi Alexander, I had the same error: sincos: /home/marcusmae/rpmbuild/BUILD/llvm/lib/VMCore/PassManager.cpp:635: void llvm::PMTopLevelManager::schedulePass(llvm::Pass*): Assertion `PI && "Expected required passes to be initialized"' failed. The solution was to add: PassRegistry &Registry = *PassRegistry::getPassRegistry(); initializeCore(Registry);

Just special case DP DSM connectors until we properly figure out how to deal with this. This resolves user regressions on GPUs with such connectors without reverting the original fix.

Dear lazydev, I'm writing an instrumentation pass that depends on AliasAnalysis. My getAnalysisUsage() looks as follows: 2453 void ThreadSanitizer::getAnalysisUsage(AnalysisUsage &AU) const { 2454 AU.addRequired<TargetData>(); 2455 AU.addRequired<AliasAnalysis>(); 2456 } and the pass initialization: 2668 char ThreadSanitizer::ID = 0; 2669

I am trying to add an analysis pass as a FunctionPass, and let LICM (LoopPass) depends upon it. So in LICM.cpp, I have the following: virtual void getAnalysisUsage(AnalysisUsage &AU) const { AU.setPreservesCFG(); AU.addRequired<DominatorTree>(); AU.addRequired<LoopInfo>(); AU.addRequiredID(LoopSimplifyID); AU.addRequired<AliasAnalysis>();
