First, I'm not sure if deleting the ExecutionEngine is all I need to clean-up... so I started with a minimal test just to check int main( int argc, char **argv ){ while( true ){ Module *M = new Module("M"); Function *F = cast<Function>(M->getOrInsertFunction("F", Type::Int32Ty, (Type*)0)); BasicBlock *BB = new

Several minor memory leaks have been fixed since llvm 2.0. -Chris > int main( int argc, char **argv ){ > while( true ){ > Module *M = new

Hi, I'm trying to use analysis results from a CallGraphSCCPass in a ModulePass. Here is the relevant code: struct MyCallGraphSCCPass : CallGraphSCCPass { ... bool runOnSCC(CallGraphSCC& scc){...} }; char MyCallGraphSCCPass::ID = 0; static RegisterPass<MyCallGraphSCCPass> X("cgscc", "Dummy CG SCC pass"); struct MyModulePass : public ModulePass {

Having a ModulePass that requires a FunctionPass that in turn requires another ModulePass results in an assertion being fired. Is this expected behavior (that seems to be undocumented), or a bug? Specifically, the following code will emit the assertion: [VMCore/PassManager.cpp:1597: virtual void llvm::ModulePass::assignPassManager(llvm::PMStack&, llvm::PassManagerType): Assertion

Hi, Does the current LLVM backend support reading in profile information (without preserving across transformations)? An earlier poster http://groups.google.com/group/llvm-dev/browse_thread/thread/4bd65dbe84394bb7 noted that accessing execution counts in a MachineFunction pass (using the BasicBlock* corresponding to the respective MachineBasicBlock) returned 0 for all blocks. Running llc with

Greetinigs, I am extending llc to include runtime checks for calls (in X86). So a call 'call target' is altered to look like this: [some check] jne error_function call target I've done this by implementing a MachineFunctionPass that is instantiated and added to the PassManager in X86TargetMachine::addPreRegAlloc. In order to create the jne-instruction I need some BasicBlock

Hi all, I was able to create a pass following [1]. Now goal is amend the pass and try to dump the call graph. I think I have properly amended the source extending my pass from CallGraphSCCPass but unfortunately every time I run it, it crashes. I tried with llvm-6 and llvm-7. I notice that if I change EP_EarlyAsPossible to anything else it does not crash but I don't see the expected string

Hello, while invoking opt with all possible optimization pairs I stumbled over a stack dump when doing -early-cse-memssa twice: $ clang -Xclang -disable-O0-optnone -S -o fannkuch7.ll -emit-llvm fannkuch7.c $ opt -S -o fannkuch7.ll -early-cse-memssa -early-cse-memssa fannkuch7.ll Questions: Is it illegal to call -early-cse-memssa twice? Are there any other incompatible optimization orders?

"A module pass can use function level passes (e.g. dominators) using getAnalysis interfacegetAnalysis<DominatorTree>(Function), if the function pass does not require any module passes." http://llvm.org/docs/WritingAnLLVMPass.html In your case, A module pass (ModPass2) is trying tu use function level pass (FunPass1) which uses module level pass (ModPass1). This is not

Hi all, I too am getting this error for x86_64 when I am trying to use the Data Structure Analysis ...I svn upped both the llvm main branch and the poolalloc today in the morning and recompiled everything from scratch : $ opt -load /home/pprabhu/llvm/llvm-install-x86-64/lib/libpoolalloc.so -ds-aa < o.bc opt: /home/pprabhu/llvm/llvm/lib/VMCore/PassManager.cpp:1418: virtual void

Hi Michael, Currently, you can run vmjc created .bc files by statically linking them with all the .o needed files. For that, you can use the llcj tool, which works more or less like GCC's gcj tool. Note that you also need to create the libvmjc.so file, which contains the standard library in native form. Do a make in the tools/vmjc/libvmjc directory. Once this is done, update the

Hi, Thanks a lot for the help! I am getting some errors though: I am on a 32 bit chroot on a x86_64 system. Thus llc guesses the wrong architecture from the module bitcode and spits out x86_64 assembly. I fixed this by adding "-march=x86" to the llc options in llcj. gcc doesn't know what -lgc is. I'm guessing it is the garbage collection library. How can I get it or

Hi, What do I need to link with vmjc created .bc files to actually run the .bc file? I tried running with lli but only got: LLVM ERROR: Program used external function 'StartJnjvmWithoutJIT' which could not be resolved! Thanks, Michael

Hi, I've managed to compile it the class down to a native executable. However, the executable runs for a while then spits out: terminate called without an active exception Aborted and dies. The program never gets to the normal output. Here is a stack trace from gdb: #0 0xf3f6baa6 in raise () from /lib/libc.so.6 #1 0xf3f6d3a8 in abort () from /lib/libc.so.6 #2 0xf41918f8 in

Hi, I'm having a hard time linking the LLVM/clang libraries in Xcode. I've been fighting this for a couple of days now, and decided to make a fresh checkout and a super-simple demo project to try and isolate the problem, but even so I'm getting undefined symbol errors in the linker for the static libraries LLVM is producing. This is really baffling, so probably I'm

Dear Prakash, Yes, DSA is still in active use, although nobody else uses the -ds-aa pass as far as I know. I tried the below sample (although ds-aa should be in libLLVMDataStructure.so and not libpoolalloc.so), and I get the same error. I've seen similar problems with other passes in our work here. My guess is that -ds-aa is requiring two passes that claim to invalidate each other; this

Dear Prakash, I believe I've fixed the problem you were having with ds-aa. Please update your poolalloc tree, recompile, and let me know if it works. -- John T.
