1 #===-- Makefile.common - Common make rules for LLVM -------*- makefile -*--====
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 can be set by setting incoming variables.
9 # The variable $(LEVEL) *must* be set:
11 # 1. LEVEL - The level of the current subdirectory from the top of the
12 # MagicStats view. This level should be expressed as a path, for
13 # example, ../.. for two levels deep.
15 # 2. DIRS - A list of subdirectories to be built. Fake targets are set up
16 # so that each of the targets "all", "install", and "clean" each build
17 # the subdirectories before the local target. DIRS are guaranteed to be
20 # 3. PARALLEL_DIRS - A list of subdirectories to be built, but that may be
21 # built in any order. All DIRS are built in order before PARALLEL_DIRS are
22 # built, which are then built in any order.
24 # 4. Source - If specified, this sets the source code filenames. If this
25 # is not set, it defaults to be all of the .cpp, .c, .y, and .l files
26 # in the current directory. Also, if you want to build files in addition
27 # to the local files, you can use the ExtraSource variable
29 # 5. SourceDir - If specified, this specifies a directory that the source files
30 # are in, if they are not in the current directory. This should include a
31 # trailing / character.
33 # 6. LLVM_SRC_ROOT - If specified, points to the top of the LLVM source tree.
35 # 7. LLVM_OBJ_ROOT - If specified, points to the top directory where LLVM
36 # object files are placed.
38 # 8. BUILD_SRC_DIR - The directory which contains the current set of Makefiles
39 # and usually the source code too (unless SourceDir is set).
41 # 9. BUILD_SRC_ROOT - The root directory of the source code being compiled.
43 # 10. BUILD_OBJ_DIR - The directory where object code should be placed.
45 # 11. BUILD_OBJ_ROOT - The root directory for where object code should be
49 # LLVM, LLVM_SRC_ROOT = BUILD_SRC_ROOT, and
50 # LLVM_OBJ_ROOT = BUILD_OBJ_ROOT.
