[llvm-dev] Question about the build

[Paul C. Anagnostopoulos via llvm-dev]

Sorry to keep posting, but I'm hoping continued evidence will enable someone to understand what is going on.

If I touch a lib/TableGen file and then build bin/llvm-tblgen.exe, Ninja rebuilds build/bin/llvm-tblgen.exe

If I touch a file and then build lib/Target/all, Ninja rebuilds both build/bin/llvm-tblgen.exe and build/NATIVE/bin/llvm-tblgen.exe. In neither case does it rebuild any .inc files.
