In fact, you can go into ANY subdirectory and just re-run make there.
Also, you might want to know about this neat `makellvm' script that's in
`llvm/utils'. It provides an easy way of doing the above 4 steps in one
For example, let's say you're working on the Sparc JIT, so you are in
the directory llvm/lib/Target/Sparc, where you modified some files. Now
you want to recompile the Sparc library, and relink lli.
llvm/lib/target/Sparc% ../../../utils/makellvm lli
That's it! For more options, run `makellvm -h', and you can also add
the directory `llvm/utils' to your path so you can just call:
llvm/lib/target/Sparc% makellvm lli
Hope that helps.
