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