[LLVMdev] compiler-rt with MSVC?

[Tony Kelman]

I’m trying to figure out how to build compiler-rt 3.5.0 with Visual Studio 
2013. In an autotools build or cmake on Linux, I believe putting the 
compiler-rt sources under llvm/projects is enough to build them 
automatically. Do I need to do anything specific to get the same with MSVC? 
I've tried setting -DLLVM_BUILD_EXTERNAL_COMPILER_RT either ON or OFF, but 
can't find any evidence of compiler-rt getting built. If I build compiler-rt 
separately, pointing it to an installed LLVM build with -DLLVM_CONFIG_PATH, 
the only thing that ends up in the install result is the sanitizer headers. 
Should this be working, or is it still under construction? When I tried with 
LLVM 3.3 I was getting a bunch of syntax errors from MSVC in compiler-rt, so 
presumably it wasn't yet MSVC-compatible at that time. Has the MSVC build 
just been disabled somewhere to avoid this?

Thanks,
Tony
