#===-- Makefile.rules - Common make rules for LLVM ---------*- Makefile -*--===#

# The LLVM Compiler Infrastructure
#
# This file was developed by the LLVM research group and is distributed under
# the University of Illinois Open Source License. See LICENSE.TXT for details.
#
#===------------------------------------------------------------------------===#
#
# 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 dependency info.
# These are platform dependent, so this is the file used to specify these
# system dependent 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 BUILT_SOURCES variable
#
# 6. LLVM_SRC_ROOT - If specified, points to the top of the LLVM source tree.
#
# 8. BUILD_SRC_DIR - The directory which contains the current set of Makefiles
# and usually the source code too (unless SourceDir is set).
#
# 9. BUILD_SRC_ROOT - The root directory of the source code being compiled.
#
# 10. BUILD_OBJ_DIR - The directory where object code should be placed.
#
# 11. BUILD_OBJ_ROOT - The root directory for where object code should be
# placed.
#
# For building,
# LLVM, LLVM_SRC_ROOT = BUILD_SRC_ROOT
#
#===-----------------------------------------------------------------------====
#
# Set the VPATH so that we can find source files.

# Library Build Rules:
#
#---------------------------------------------------------
# Handle the LIBRARYNAME option - used when building libs...
#---------------------------------------------------------
#
# When libraries are built, they are allowed to optionally define the
# DONT_BUILD_RELINKED make variable, which, when defined, prevents a .o file
# from being built for the library. This .o files may then be linked to by a
# tool if the tool does not need (or want) the semantics a .a file provides
# (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
# of it. For this reason, sometimes it's useful to use libraries as .a files.
