Hi everyone, I just had a question - I am aware that LLVM supports it's own form of RTTI ( using dyn_cast<>() ,etc) but I wish to use C++ RTTI currently. I have tried building with "cmake -G "Unix Makefiles" -LLVM_ENABLE_RTTI=ON" but that doesnt seem to remove the "fno-rtti" flag from llvm-config and I still get an error when I try using "dynamic_cast<>" from C++ RTTI. Is there any way to remove the "fno-rtti" flag from the llvm-config ( seen on running "llvm-config --cxx...

...LVM_ENABLE_EH:BOOL*Build LLVM with exception-handling support. This is necessary if you wish to link against LLVM libraries and make use of C++ exceptions in your own code that need to propagate through LLVM code. Defaults to OFF. It seems to be exactly what I require. I enabled LLVM_ENABLE_EH and LLVM_ENABLE_RTTI but it doesn't seems to work. I also tested it with /EHs /EHsc in msvc. It makes no difference I also looked at the ExceptionDemo.cpp, but it seems to be unsupported under windows. Do I need to try catch and retrhow in my ir_func() ?

Hello, I get a crash in my program that uses exceptions and the LLVM JIT, even though the exceptions are controlled and thrown/catched in a part that doesn't deal with LLVM. I noticed that llvm-config --cxxflags includes the -fno-exceptions flag. Do I need to throw no exceptions whatsoever in my application to use LLVM JIT? As a minimal example, I modified the code in

Hi all, I am having some some trouble with LLVM 3.8... I built it with GCC 4.8.2 with cmake and no special CXX/C flags. That means in case of GCC that RTTI is switched on, I believe. However, building my MCJIT application against the just built LLVM and linking results in: libqdp.a(qdp_llvm.o):(.rodata._ZTIN4llvm8FCmpInstE[_ZTIN4llvm8FCmpInstE]+0x10): undefined reference to `typeinfo for

That seems to work (see below). $ cd
