[LLVMdev] Building a backend outside the LLVM source tree

[Torgny Andersson]

Hi!
I'm trying to build a backend outside the LLVM source tree. My directory
structure is as follows:
  llvm -- the root of the LLVM source tree
  llvm/lib/Target -- where the standard backends are stored (Sparc, etc).
  my_dir/my_backend -- where I store the backend I'm writing.

I've been fiddeling with the variables documented in the
llvm/Makefile.common (LEVEL, LLVM_SRC_ROOT, PROJ_SRC_DIR, etc) but without
success. Is what I'm trying to do possible with the LLVM buildsystem? If so,
how?

Thank you!
