[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

Here, by the way, is the stack trace leading to the failed assertion.

[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.
