+# 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.
+# 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. Source - If specified, this sets the source code filenames. If this
+# 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. 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.

+# 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.
