When migrating my project to 2.9, I've encountered a strange segfault where if a ModulePass's getAnalysisUsage adds LoopInfo and DominatorTree, then llvm::PMTopLevelManager::findAnalysisUsage will segfault. What's odd is that if I rearrange this (add required for DominatorTree before LoopInfo), it does not segfault. I realize that LoopInfo requires and preserves DominatorTree, but this

I just updated my llvm sources (revision 164794.) and I see the error, "overriding non-deleted function" when building with gcc 4.7.0 and passing -std=c++11. /usr2/sidneym/llvm/tools/install/bin/c++ -D_GNU_SOURCE -D_DEBUG -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -std=c++11 -fPIC -fvisibility-inlines-hidden -I/local/scratch/llvm-tmp/build/lib/VMCore

Thanks for the response. I do have assertions enabled, and none of them are getting hit. I did do a search of the mailing list for the past year (approximately) before writing my email, and what I found was that you should be allowed to use LoopInfo and other analysis function passes from a module pass, with the only difference being that getAnalysis is passed the function. The example code I

Hi Michael, hi Duncan, yesterday I stumbled over something that might be related. At least I could also just be doing some initialization wrong or something in this direction... In my case, I hit a segfault in PassInfo::isAnalysisGroup() after PassManager.add(myModulePass) is called. My setup seems fairly simple, the attached code should reproduce the error. Compile with g++ test.cpp

Your constructor is not calling initializeTestMPPass(), and you're using RegisterPass which I think was deprecated in favor of INITIALIZE_PASS. You can look at, for example, lib/Transforms/Scalar/IndVarSimplify.cpp for examples of how to initialize, e.g. having "INITIALIZE_PASS_DEPENDENCY(LoopInfo)" sandwiched between BEGIN and END. Note that you'll want a forward declaration of

I've fixed this specific error in r164813. Please let me know if there are more behind it.

I suggest you build LLVM with assertions enabled - then you should get a helpful error message rather than a segfault. I think you are not allowed to

Hi all, This patch, though large, simply moves lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h. Why? Because this module has nothing to do with analysis. It simply defines an interface to the debug info MDNodes. In fact, the lib/VMCore/AsmWriter.cpp file performs a layering violation, because it calculates the DWARF tag

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'm trying to compile vmkit on a x86_64 linux box with gcc-4.1.2, but I'm running into troubles because of various problems with casts between pointers and integers. Is there anybody who succeeded in this task? Az I see, some of the problems can be fixed with an appropriate typedef/macro declaration, but in VMCore/JavaObject.cpp some lowlevel bitmanipulation is used, to mark

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

I'm in a debug build with assertions turned on for llvm-2.9, and I get a segfault whenever I try to schedule one of my own immutable passes in a pass manager. It seems that one of the passes that I'm scheduling (IndVarSimplify) attempts to ask for TargetData if it's available (I'm not providing it), and that's when it segfaults. If I split that pass into it's own pass

Hi all, I just forgot to ./configure with CC=gcc-4.2 CXX=g++-4.2, getting the (broken-for-LLVM) gcc-4.1 as a compiler. The error message that I got was this: make[1]: Entering directory `/home/jo/llvm-wrk/lib/VMCore' make[1]: *** No rule to make target `/home/jo/llvm-wrk/Release/bin/tblgen', needed by `/home/jo/llvm-wrk/lib/VMCore/Release/Intrinsics.gen.tmp'. Stop.

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 all, I am currently trying to build vmkit on OSX Lion. I am using release versions of llvm/clang as 3.2 and have tired both vmkit HEAD, 3.2 and vmkit2. I have gotten farthest with 3.2 but the current build error that I am getting is llvm[3]: Compiling JavaObject.s for Release+Asserts build /vmkit/lib/j3/VMCore/Release+Asserts/JavaObject_gc.s:1647:2: error: invalid instruction mnemonic

Hello folks, Now that the includes are sortable and I have another chunk of free time, I'll be making another attempt at the mass renaming from VMCore to IR for LLVM. I'm also planning to move the header files currently in the top level for LLVM down into the appropriate subdirectory. I'll create an IR directory for the headers that really belong to that library component. However,
