           Summary: Instructions don't point out that Makefile is needed in
                    object tree as well as source tree
           Product: Documentation
           Version: trunk

               URL: http://llvm.org/docs/WritingAnLLVMPass.html#makefile
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P2

The instructions for writing the makefile says to place it the source tree at a
certain point.  The next section says, to build the pass, just type 'gmake' in
the local directory.  However, this doesn't work: if the source .cpp file is at
LLVM_SRC_ROOT/some_path/pass.cpp, then you need to copy the Makefile to 
LLVM_OBJ_ROOT/some_path/Makefile, and type 'make' in that directory, not the
source directory.
