Moved Makefile.common to Makefile.rules. This makes project Makefiles easier to support, and allows for easier overriding of default configuration values that used to be in Makefile.common. Modified Makefile.config.in to determine paths for directories (like LLVM_SRC_ROOT) and to use the pwd binary as opposed to the shell builtin (this works better for symbolic links). llvm-svn: 8377

#===-- 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 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
|
|
# MagicStats view. 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. Also, if you want to build files in addition
|
|
# to the local files, you can use the ExtraSource variable
|
|
#
|
|
# 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. 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
|
|
# placed.
|
|
#
|
|
# For building,
|
|
# LLVM, LLVM_SRC_ROOT = BUILD_SRC_ROOT
