+# source directory. 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
# 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

-# 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.
+# For building,
+# LLVM, LLVM_SRC_ROOT = PROJ_SRC_ROOT
#
-# 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.
