Tried a small test just now to see how exception handling on Windows is getting on, and it seems to work except for one thing. clang-cl /EHsc (the Microsoft compiler option to enable exceptions) doesn't do anything; they remain disabled. However, -Xclang -fcxx-exceptions succeeds. Is this a bug in the handling of compatibility options or am I missing something? -------------- next part -------------- An HTML attachment was scrubbed.....

Thank you very much,It works! And some Q&A I meet,may help somebody: 1. If zlib build with 32bit,should use MSVC's 'vcvars32.bat'; 2. Add '-Z7' to CXXFLAGS can release *.pdb file for VS2017 'Step Into' debug, such as: CXXFLAGS="-EHsc -Z7"; 3. If Somebody write a demo in VS2017 3.1 change libxapian.a's name to libxapian.lib; 3.2 make sure the Runtime Library is /MT, can change it at project property page, C/C++-->Code Generation-->Runtime Library; 3.3 add Rpcrt4.lib and Ws2_32.lib to linker input; 3.4 copy z...

I don't suppose anyone knows what (or how to find out what) the actual command to compile Kaleidoscope is?

I got as far as cl /EHsc /I\d\llvm-2.6\include /I\llvm\include /wd4355 toy.cpp which successfully generated toy.obj and spat out 86 link time error messages -- as expected, it needs the libraries specified. cmakelists.txt says set(LLVM_LINK_COMPONENTS core jit interpreter native) so I made a guess at the .lib file corresp...

wine is 1.1.21 I use VC10 beta1 compiler on window, and it's work fine. The Windows is pure: not install any software. That mean is: The VC 10 is a portable software. I can compile main.cpp use: ./cl.exe /EHsc main.cpp it's OK! the main.exe created! but if i do: ./cl.exe /EHsc /Zi main.cpp it's fair. the error information is: > loaden at qpsoft:~/qpcb/bin$ ./cl.exe /EHsc /Zi main.cpp > fixme:heap:HeapSetInformation 0x540000 0 0x32fd88 4 > fixme:heap:HeapSetInformation (nil) 1 (nil)...

I would really like to know about how to apply the patch for making MSVC-built LLVM executables lighter. But aside from that, I also want to know what LLVM does to CMake's default setting of /EHsc. I want to keep that setting on, but I can't figure out how. Any help is appreciated. Thanks in advance. P.S. The CMAKE_CXX_FLAGS variable isn't helping at all, otherwise I wouldn't be asking this. -------------- next part -------------- An HTML attachment was scrubbed... URL: <h...

...ed 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 "-DCMAKE_CXX_FLAGS="/std:c++17 /MT /EHsc /permissive-"" but this also didn't work. Specifying these on the CXXFLAGS environment variable didn't do anything either. I was using the same session of the Developer Command Prompt, but I made sure to run "refreshenv" to take the new environment from the registry be...

...y 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() ?
