#===-- 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:
#
# 6. LLVM_SRC_ROOT - If specified, points to the top of the LLVM source tree.
#
-# 7. LLVM_OBJ_ROOT - If specified, points to the top directory where LLVM
-# object files are placed.

# 8. BUILD_SRC_DIR - The directory which contains the current set of Makefiles
# and usually the source code too (unless SourceDir is set).
