[cfe-commits] PATCH: Rough-cut auto-detection of a build directory location for the tooling framework

[Daniel Jasper]

I have tried using it by putting a symlink to compile_commands.json into my
llvm root and then use clang-check from within <llvm root>/tools/clang like
this:

$ clang-check lib/Tooling/CompilationDatabase.cpp
LLVM ERROR: Error while opening JSON database: No such file or directory

It works find if I supply the full path:
$ ~/clang/build/bin/clang-check $PWD/lib/Tooling/CompilationDatabase.cpp
Processing:
/home/djasper/clang/llvm/tools/clang/lib/Tooling/CompilationDatabase.cpp.

So, it does not go up the directory tree far enough, as the
Directory.empty() will be true before my symlink  is reached. Can this be
added? And can you add a test for such a case?

  +++ tools/clang/lib/Tooling/CompilationDatabase.cpp (working copy)
  ...
  +#include "llvm/Support/raw_ostream.h"

I don't think you need this new include.
