#===------------------------------------------------------------------------===#

#

# 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 dependency info.

# These are platform dependent, so this is the file used to specify these

# system dependent operations.

#

# 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

# 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

# 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. 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. SOURCES - 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.

#

# 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. PROJ_SRC_DIR - The directory which contains the current set of Makefiles

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

#

# 9. PROJ_SRC_ROOT - The root directory of the source code being compiled.

#

# 10. PROJ_OBJ_DIR - The directory where object code should be placed.

#

# 11. PROJ_OBJ_ROOT - The root directory for where object code should be

# placed.

#

# For building,

# LLVM, LLVM_SRC_ROOT = PROJ_SRC_ROOT
