3 # This file is included by all of the LLVM makefiles. This file defines common
4 # rules to do things like compile a .cpp file or generate dependancy info.
5 # These are platform dependant, so this is the file used to specify these
6 # system dependant operations.
8 # The following functionality may be set by setting incoming variables:
10 # 1. LEVEL - The level of the current subdirectory from the top of the
11 # MagicStats view. This level should be expressed as a path, for
12 # example, ../.. for two levels deep.
14 # 2. DIRS - A list of subdirectories to be built. Fake targets are set up
15 # so that each of the targets "all", "install", and "clean" each build.
16 # the subdirectories before the local target.
18 # 3. Source - If specified, this sets the source code filenames. If this
19 # is not set, it defaults to be all of the .cpp, .c, .y, and .l files
20 # in the current directory.
23 # Default Rule: Make sure it's also a :: rule
26 # Default for install is to at least build everything...
