[LLVMdev] problem with execution engine on windows

[Viktar Zviarovich]

Dear llvm-dev,

First of all I'd like to thank LLVM developers for doing a great job!

I am trying to use LLVM libraries on Windows using Visual Studio environment and everything works very smoothly until it comes to the execution engine. I construct a module and obtain a pointer to the function in it using ExecutionEngine::getPointerToFunction but calling this function (after appropriate cast) causes the following error:

Unhandled exception at 0x0122a5bc in sampl.exe: 0xC000001E:  An attempt was made to execute an invalid lock sequence.

The function I am trying to call is trivial (took it from the tutorial just for testing purposes) and has C calling conventions. The execution engine returned by ExecutionEngine::create is Interpreter.

Am I doing something wrong or is it a bug?

And another question: is JIT supported on Windows?

Thank you in advance,
Viktar
