#===-- Makefile.common - Common make rules for LLVM -------*- makefile -*--====
#
# 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 can be set by setting incoming variables.
# The variable $(LEVEL) *must* be set:
#
# 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. DIRS are guaranteed to be
# built in order.
#
# 3. PARALLEL_DIRS - A list of subdirectories to be built, but that may be
# built in any order. All DIRS are built in order before PARALLEL_DIRS are
# built, which are then built in any order.
#
# 4. 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. Also, if you want to build files in addition
# to the local files, you can use the ExtraSource variable
#
# 5. SourceDir - If specified, this specifies a directory that the source files
# are in, if they are not in the current directory. This should include a
# trailing / character.
#
# 6. PROJ_COMPILE - If set to 1, then this makefile can also be used to
# compile other projects using llvm. Note if this option is set then the
# following *must* hold
# PROJLEVEL should be set to the top of the source directory for the
# project files
# LEVEL should be set to the top of LLVM source tree
# LLVM_LIB_DIR should be set to the top of the LLVM build tree
#

# gross and should be autoconfiscated (automake actually), but should hopefully

# (linking in only object files that are "needed"). If a library is never to
# be used in this way, it is better to define DONT_BUILD_RELINKED, and define
# BUILD_ARCHIVE instead.
#
# Some libraries must be built as .a files (libscalar for example) because if
# it's built as a .o file, then all of the constituent .o files in it will be
# linked into tools (for example gccas) even if they only use one of the parts
