No, if I remember correctly, mostly only the clang source files that have
changed get compiled. I think certain LLVM library's cause parts of clang to
be rebuild though. I remember working on some parts of LLVM would seem to
cause the clang compilations to take a long time compared to when I would
modify other files in LLVM. On Linux using *configure *I used to rename *
tools/clang* which keeps the LLVM build system from trying to compile clang
also. With CMake+VS you can disable compilation of each project separately.
