|
# 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 ::
