Hi Manuel,

Even in your usual case --- "how do I parse this TU" --- the input file
is not a discriminating key : this is why we get CompileCommands from
the CompilationDatabase. At some point, you need to choose one
CompilationCommand amongst several. I believe the real discriminating
key is the ouput file (with the build system I know). Beside, this would
enable other usages for the CompilationDatabase. It seems to me it is
good to have the input file as a key, but this is not enough.

Cheers,
