...ginally I used a builtin Clang in the system and it does not produce this issue. When I search for this issue on Google, it seems to be relevant to “RTTI”. But as I know LLVM is built by default -fno-rtti. I also explicitly turned off it.

I configure LLVM build with this command cd llvm-8.0.0.src & md buildsys-x64-MT & cd buildsys-x64-MT & cmake -G "Ninja" -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_BUILD_TYPE=Release -DLLVM_USE_CRT_RELEASE=MT -DLLVM_ENABLE_RTTI=1 -DLLVM_ENABLE_TERMINFO=OFF -DCMAKE_INSTALL_PREFIX=../x64-MT ..

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

...9;s architecture to be sure. Could this be pointing to something I'm doing wrong in my LLVM setup, or is it just slow? I'm reasonably certain I'm compiling LLVM in optimized mode, but for reference, this is my build line:     cmake .. -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_EH=ON -DLLVM_ENABLE_RTTI=ON -DLLVM_REQUIRES_RTTI=ON -DLLVM_ENABLE_CXX1Y=ON -DLLVM_LINK_LLVM_DYLIB=ON -DLLVM_ENABLE_FFI=ON -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_OPTIMIZED_TABLEGEN=ON -DCMAKE_INSTALL_PREFIX="/opt/llvm/install" The overall time split, from valgrind, between shared libraries in my code is:     80.48%...

Are you using static linking, -DBUILD_SHARED_LIBS, or -DLLVM_LINK_LLVM_DYLIB?

Hi. I'm trying to build LLVM 10.0.0 with CMake on the command line (Developer Command Prompt for VS2019) and I need to know how to switch to a static runtime. I've tried setting LLVM's variable for this, but it didn't work. I still have a dynamic runtime. Along with that, I also need to know how to enable C++ exceptions. One thing I tried was to do

I configured with this command: " cmake ../llvm -G"Visual Studio 16 2019" -A Win32 -Thost=x64 -DLLVM_ENABLE_EH=ON -DCMAKE_BUILD_TYPE=Release -DLLVM_USE_CRT_RELEASE=MT -DLLVM_ENABLE_RTTI=ON -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;lld;libcxx;libcxxabi" -DCMAKE_CXX_FLAGS="/permissive- /D_SILENCE_ALL_CXX17_DEPRECATION_WARNINGS" -DCMAKE_CXX_STANDARD=17 " and when building the target ALL_BUILD.vcxproj I redirected the output to a file. I'm attaching...

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

HI Stefan, CC'ing Reid Kleckner, who might have some insight here, and llvm-dev as this may be of interest to other windows JIT users.
