        <pre>I'd like to file a new issue that option "-p" (PreservePaths) of "llvm-cov
gcov" does not works well on windows.
(codes here
<a href="https://github.com/llvm-mirror/llvm/blob/master/lib/IR/GCOV.cpp#L525">https://github.com/llvm-mirror/llvm/blob/master/lib/IR/GCOV.cpp#L525</a>)
Since windows usually use "\\" as path delimiter like
"C:\\Documents\\main.cpp".

Environment:
Windows: 10 pro
clang+llvm: 3.8.275480

llvm-cov (from msys2)
msys2: 2.7.0(0.306/5/3) x86_64
llvm-cov:
  LLVM (<a href="http://llvm.org/">http://llvm.org/</a>):
  LLVM version 3.8.0svn
  Optimized build.
  Built Dec  1 2015 (10:25:18).
  Default target: x86_64-pc-msys
