8 ##===----------------------------------------------------------------------===##
10 # This file is included by all of the LLVM makefiles. This file defines common
11 # rules to do things like compile a .cpp file or generate dependency info.
12 # These are platform dependent, so this is the file used to specify these
13 # system dependent operations.
15 # The following functionality can be set by setting incoming variables.
16 # The variable $(LEVEL) *must* be set:
18 # 1. LEVEL - The level of the current subdirectory from the top of the
19 # MagicStats view. This level should be expressed as a path, for
20 # example, ../.. for two levels deep.
22 # 2. DIRS - A list of subdirectories to be built. Fake targets are set up
23 # so that each of the targets "all", "install", and "clean" each build
24 # the subdirectories before the local target. DIRS are guaranteed to be
27 # 3. PARALLEL_DIRS - A list of subdirectories to be built, but that may be
28 # built in any order. All DIRS are built in order before PARALLEL_DIRS are
29 # built, which are then built in any order.
31 # 4. Source - If specified, this sets the source code filenames. If this
32 # is not set, it defaults to be all of the .cpp, .c, .y, and .l files
33 # in the current directory. Also, if you want to build files in addition
34 # to the local files, you can use the ExtraSource variable
36 # 5. SourceDir - If specified, this specifies a directory that the source files
37 # are in, if they are not in the current directory. This should include a
38 # trailing / character.
40 # 6. LLVM_SRC_ROOT - If specified, points to the top of the LLVM source tree.
42 # 8. BUILD_SRC_DIR - The directory which contains the current set of Makefiles
43 # and usually the source code too (unless SourceDir is set).
45 # 9. BUILD_SRC_ROOT - The root directory of the source code being compiled.
47 # 10. BUILD_OBJ_DIR - The directory where object code should be placed.
49 # 11. BUILD_OBJ_ROOT - The root directory for where object code should be
53 # LLVM, LLVM_SRC_ROOT = BUILD_SRC_ROOT
55 #===-----------------------------------------------------------------------====

445 # Handle the LIBRARYNAME option - used when building libs...

448 # When libraries are built, they are allowed to optionally define the
449 # DONT_BUILD_RELINKED make variable, which, when defined, prevents a .o file
450 # from being built for the library. This .o files may then be linked to by a
451 # tool if the tool does not need (or want) the semantics a .a file provides
452 # (linking in only object files that are "needed"). If a library is never to
453 # be used in this way, it is better to define DONT_BUILD_RELINKED, and define
454 # BUILD_ARCHIVE instead.
456 # Some libraries must be built as .a files (libscalar for example) because if
457 # it's built as a .o file, then all of the constituent .o files in it will be
458 # linked into tools (for example gccas) even if they only use one of the parts
459 # of it. For this reason, sometimes it's useful to use libraries as .a files.
