[cfe-users] Confusion about building llvm/clang

[Edward Diener]

In the instructions at http://clang.llvm.org/get_started.html it says 
that after the initial run of 'llvm/configure' and 'make' I can 
subsequentally build clang from the clang directory level. This makes 
sense, but does this work after I update both llvm and clang ?

Later on, however, the instructions say:

"Once you have checked out Clang into the llvm source tree it will build 
along with the rest of llvm. To build all of LLVM and Clang together all 
at once simply run make from the root LLVM directory."

This is confusing. I thought running 'make' from the clang directory 
level will build all of llvm and clang since clang depends on llvm. What 
am I missing here ?
