[cfe-dev] [PATCH] get access to all files of compilation database

[Tobias Koenig]

Hej,

when implementing some static code analysis tool based on clang, you often 
want to introspect the complete code base of a project. With the current API, 
you have to specify the list of files explicitly by passing them as second 
parameter to the constructor of tooling::ClangTool and
the common approach seems to be to pass in this list as command line 
parameters to your application.
Now I wonder whether the CompilationDatabase class (which has loaded all the 
compilation information from compile_commands.json already) could provide a 
getter method to retrieve the list of files and passing it to 
tooling::ClangTool directly.

Attached is a patch for that. No idea how to handle the usage of 
FixedCompilationDatabase in this case though.

Any suggestions, objections, comments?

Ciao,
Tobias
