[llvm-dev] Orc JIT v2 breaks OpenMP in 11.x branch?
Greetings, Lang and other JITters, Last week I moved our Orc v2-based app from top-of-tree to the new 11.x branch, and it no longer handles C++ code containing OpenMP directives correctly. More specifically, if I JIT compile a function containing OpenMP parallel/for pragmas, using a release version of LLVM, the code compiles and seems to work, but if I try to write the module's bitcode to file, I get the following error message: Invalid record (Producer: 'LLVM11.0.0' Reader: 'LLVM 11.0.0'). If I use a debug version of LLVM, compilation fails with a broken assertion: .../llvm/lib/IR/Instructions.cpp:455: void llvm::CallInst::init(llvm::FunctionType*, llvm::Va lue*, llvm::ArrayRef<llvm::Value*>, llvm::ArrayRef<llvm::OperandBundleDefT<llvm::Value*> >, const llvm::Twine&): Assertion `(i > = FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed. The same code compiles correctly using clang from the command line. It also works fine using Orc v2 in the master branch of LLVM from the end of May. The problems are way too deep in the LLVM code for me to make any sense of them... Does anybody else have a clue what might have happened to Orc and/or OpenMP in the past couple months to trigger this? Geoff

[llvm-dev] Orc JIT v2 breaks OpenMP in 11.x branch?
Hi Geoff, Nothing in that backtrace leaps out at me. Based on the stack trace and description my first guess would be a clang misconfiguration rather than a JIT bug. How is that clang invocation being made? Is it from inside a callback from ORC, or is it before you add your module to the JIT? -- Lang.
