        <pre>I've been following some of the blog posts with regard to Windows support, as
the improved link times sound pretty great (lld-link is currently crashing,
though not in a simple test). This is from the latest windows x64 installer. 

When I try to use ghash, Visual Studio isn't able to display anything via the
watch window (or mouse over).  Without GHASH, this seems fine in the most basic
of tests (int main, with a local int variable). 

\_temp>clang-cl --version
clang version 7.0.0 (trunk)
Target: x86_64-pc-windows-msvc
Thread model: posix
InstalledDir: C:\Program Files\LLVM_7\bin

clang-cl -c -Z7 -MTd -o foo.obj foo.cpp -mllvm -emit-codeview-ghash-section
lld-link /DEBUG:GHASH foo.obj


Am I overlooking anything here?  

Thanks!</pre>
