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

|
#
|
|
# 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. Source - 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
