# 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
+# 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
# in the current directory. Also, if you want to build files in addition
# to the local files, you can use the ExtraSource variable

-# make command line (ie, make ENABLE_PROFILING=1)
+# 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.
#
-
-# When ENABLE_PROFILING is enabled, the llvm source base is built with profile
-# information to allow gprof to be used to get execution frequencies.
+# 6. LLVM_SRC_ROOT - If specified, points to the top of the LLVM source tree.

+# and usually the source code too (unless SourceDir is set).
#

#
-# When libraries are built, they are allowed to optionally define the

-# 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.
