By default, CMake will use /EHsc when compiling for the Windows
platform, with no option to change this that I am aware of. If a project
wants different settings, it needs to handle this itself. And in fact,
LLVM 3.4.2 conditionally modifies /EHsc to /EHs-c- in
cmake/modules/LLVMProcessSources.cmake, so I wouldn't be surprised if
LLVM 10.0.0 does something similar (I don't have a more recent version
of LLVM lying about, so I can't check).
To figure out what option(s) you need to set or what files you need to
modify, you either need to ask the LLVM developers, or dig through the
LLVM cmake project to figure out what it is doing with the /EHsc option.

Alright, thanks. What about enabling C++ exceptions? I tried setting
LLVM_ENABLE_EH to On, but it didn't help. Setting CMAKE_CXX_FLAGS to
/EHsc doesn't help either.
