#===-- Makefile.common - Common make rules for LLVM -------*- makefile -*--====
#
# This file is included by all of the LLVM makefiles. This file defines common
-# rules to do things like compile a .cpp file or generate dependancy info.
-# These are platform dependant, so this is the file used to specify these
-# system dependant operations.

#
# The following functionality can be set by setting incoming variables.
# The variable $(LEVEL) *must* be set:
# are in, if they are not in the current directory. This should include a
# trailing / character.
#
-# 6. PROJ_COMPILE - If set to 1, then this makefile can also be used to
-# compile other projects using llvm. Note if this option is set then the
-# following *must* hold
-# PROJLEVEL should be set to the top of the source directory for the
-# project files
-# LEVEL should be set to the top of LLVM source tree
-# LLVM_LIB_DIR should be set to the top of the LLVM build tree
+# 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.
+#
+# 11. BUILD_OBJ_ROOT - The root directory for where object code should be
