20 # This section of the Makefile determines what is where. To be
21 # specific, there are several locations that need to be defined:
23 # o LLVM_SRC_ROOT : The root directory of the LLVM source code.
24 # o LLVM_OBJ_ROOT : The root directory containing the built LLVM code.
26 # o PROJ_SRC_DIR : The directory containing the code to build.
27 # o PROJ_SRC_ROOT : The root directory of the code to build.
29 # o PROJ_OBJ_DIR : The directory in which compiled code will be placed.
30 # o PROJ_OBJ_ROOT : The root directory in which compiled code is placed.
