LLVM/Clang Visual Studio build errors

Clang Frontend Using Clang
#1

I’ve installed the VS extension and tried to build some code with it. I get the following errors:

1>clang cl.exe : error : argument unused during compilation: ‘/Zi’
1>clang cl.exe : error : argument unused during compilation: ‘/MP’
1>clang cl.exe : error : argument unused during compilation: ‘/Gm-’
1>clang cl.exe : error : argument unused during compilation: ‘/EHa’
1>clang cl.exe : error : argument unused during compilation: ‘/GS’
1>clang cl.exe : error : argument unused during compilation: ‘/Gy’
1>clang cl.exe : error : argument unused during compilation: ‘/fp:precise’
1>clang cl.exe : error : argument unused during compilation: ‘/FdRelease\incore.pdb’
1>clang cl.exe : error : argument unused during compilation: ‘/Gd’

Am I correct in guessing that these are just MSVC flags that Clang’s cl.exe driver doesn’t understand yet, so it bails?

#2

Yes. Or rather, it's not so much that it doesn't understand them, but
their functionality is not yet implemented. We're tracking this at
http://llvm.org/bugs/show_bug.cgi?id=17129
