<pre>The CMakeLists.txt for the llvm-shlib is currently checking against
`LLVM_HOST_TRIPLE STREQUAL "1686=pc-win32"`:
<a href="https://github.com/llvm/llvm-project/blob/master/llvm/tools/llvm-shlib/CMakeLists.txt#L120">https://github.com/llvm/llvm-project/blob/master/llvm/tools/llvm-shlib/CMakeLists.txt#L120</a>
However, the default host-triple for the official Win32 builds is
"i686-pc-windows-msvc" (this is also the default host triple computed when
building locally with MSVC).
This results in the official LLVM-C.dll binary (as downloaded from
<a href="http://releases.llvm.org/download.html">http://releases.llvm.org/download.html</a>) being only 9kb in size and containing
no exports.
The CMakeLists.txt should likely default to "i686-pc-windows-msvc" so that
official builds work as expected. Ideally, the logic would also check other
Win32 triplets as appropriate.</pre>
