The stack trace: llvm::PMTopLevelManager::addImmutablePass(llvm::ImmutablePass*) llvm::PMTopLevelManager::schedulePass(llvm::Pass*) moduleToObjectFile(llvm::Module*,std::string&,llvm::LLVMContext&) Sometimes it doesn't crash because TargetRegistry::lookupTarget() returns an error which says it doesn't support the current target > On Mar 24, 2016, at 1:14 AM, Mehdi Amini

Sorry, that's a pure crash I think, assertions are not triggered. Xcode doesn’t map those 2 functions to line numbers because they’re in precompiled libraries On Mar 24, 2016, at 1:44 AM, Mehdi Amini <mehdi.amini at apple.com <mailto:mehdi.amini at apple.com>> wrote: > >> On Mar 23, 2016, at 5:41 PM, Lorenzo Laneve <lore97drk at icloud.com <mailto:lore97drk at

Assuming you are talking about this line: passmanager.add(tliwp); I don't see anything obviously wrong. Are you hitting an assertion or a pure crash? (if LLVM not built with assertions, please rebuild). What does your debugger gives you as a stracktrace? -- Mehdi > On Mar 23, 2016, at 3:44 PM, Lorenzo Laneve via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Sorry in

You may want to try adding this code (copy/pasted from llc.cpp): // Initialize targets first, so that --version shows registered targets. InitializeAllTargets(); InitializeAllTargetMCs(); InitializeAllAsmPrinters(); InitializeAllAsmParsers(); // Initialize codegen and IR passes used by llc so that the -print-after, // -print-before, and -stop-after options work. PassRegistry

This code path is not likely to crash usually. Did you build LLVM yourself? Which version are you using and can you reduce the test case to be "minimal" so that someone can reproduce?

Update: Sorry my bad. I built llvm and tried it with debugging version. It was an assertion (IR/LegacyPassManager.cpp:764) saying that it expects all immutable passes to be initialized. > On Mar 24, 2016, at 2:00 AM, Lorenzo Laneve <lore97drk at icloud.com> wrote: > > I’m using LLVM 3.8.0, and no, it’s the precompiled version > That’s why it doesn’t give me enough info for

So we come back to my earlier comment: can you produce a one-file, < 100 lines that reproduce the issue? -- Mehdi > On Mar 24, 2016, at 10:16 AM, Lorenzo Laneve <lore97drk at icloud.com> wrote: > > Those lines of code are in a function that is called before calling the moduleToObjectFile() function > > On Mar 24, 2016, at 6:07 PM, Mehdi Amini <mehdi.amini at

Those lines of code are in a function that is called before calling the moduleToObjectFile() function > On Mar 24, 2016, at 6:07 PM, Mehdi Amini <mehdi.amini at apple.com> wrote: > > You may want to try adding this code (copy/pasted from llc.cpp): > > // Initialize targets first, so that --version shows registered targets. > InitializeAllTargets(); >

The problems happens because PMTopLevelManager::findAnalysisPassInfo(AnalysisID AID) returns nullptr in PMTopLevelManager::addImmutablePass(ImmutablePass *P). This because PassRegistry::getPassRegistry()->getPassInfo(AID) call in it returns nullptr as well. Should I probably register the pass I want to add with PassRegistry::registerPass(const PassInfo &PI, bool ShouldFree) ? I didn’t do it

Passes all need to be initialized before they are added into a pass manager. Are you calling TargetLibraryInfoWrapperPass::initializePass anywhere? -Chris > On Mar 24, 2016, at 10:41 AM, Lorenzo Laneve via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > The problems happens because PMTopLevelManager::findAnalysisPassInfo(AnalysisID AID) returns nullptr in

Hello, I'm trying to minimize the processing time for llc -O3 by using a three step compilation process of 1. llc input.bc -stopafter=targetlibinfo -o input.mir 2. llc -run-pass={....min passes...} input.mir -o opt.mir 3. llc -startafter=machine-opt-remark-emitter -filetype=obj opt.mir -o final.obj Examining the passes produced by llc for O1,O2,O3 I compared (with XXX = {1,2,3}): llc

Hi, I'm a PhD student doing phase ordering as part of my PhD topic and I would like to ask some questions about LLVM. Executing the following command to see what passes does OPT execute when targeting a SPARC V8 processor: /opt/clang+llvm-3.7.1-x86_64-linux-gnu-ubuntu-15.10/bin/llvm-as < /dev/null | /opt/clang+llvm-3.7.1-x86_64-linux-gnu-ubuntu-15.10/bin/opt -O3 -march=sparc -mcpu=v8

ExecutionEngine::create() can return NULL with an empty error message (admittedly, it did so because of global variable initialization problems). The code currently lets NULL go through if ErrorMsg is empty, and segfaults later. When EE is NULL but ErrorMsg is empty, simply do not try to print it and exit. Index: tools/lli/lli.cpp

Hi Arnold, thanks for the detailed setup. Still, I haven't figured out the right thing to do. I would need only the native target since all generated code will execute on the JIT execution machine (right now, the old JIT interface). There is no need for other targets. Maybe it would be good to ask specific questions: How do I get the triple for the native target? How do I setup the

I would need this to work when calling the vectorizer through the function pass manager. Unfortunately I am having the same problem there: LV: The Widest type: 32 bits. LV: The Widest register is: 32 bits. It's not picking the target information, although I tried with and without the target triple in the module. Any idea what could be wrong?
