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

You don't need to change the makefiles. Simply update the configure
script as explained here <a
href="http://llvm.org/docs/WritingAnLLVMBackend.html#Preliminaries">http://llvm.org/docs/WritingAnLLVMBackend.html#Preliminaries</a><br>
<br>
Have your backend's folder live in llvm/lib/Target/ with the others.<br>
