#===-- 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:
#
# 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
#
#===-----------------------------------------------------------------------====
# Configuration file to set paths specific to local installation of LLVM
#
include $(LEVEL)/Makefile.config
# These are options that can either be enabled here, or can be enabled on the
# make command line (ie, make ENABLE_PROFILING=1)
#
# When ENABLE_PROFILING is enabled, the llvm source base is built with profile
# information to allow gprof to be used to get execution frequencies.
#
#ENABLE_PROFILING = 1
# When ENABLE_PURIFY is enabled, the LLVM tools are linked with purify (which
# must be locally installed) to allow for some automated memory error debugging.
#
#ENABLE_PURIFY = 1
# When ENABLE_OPTIMIZED is enabled, Release builds of all of the LLVM code are
# turned on, and Debug builds are turned off.
#
#ENABLE_OPTIMIZED = 1
# Figure out how to do platform specific stuff on this platform. This is really
# gross and should be autoconfiscated (automake actually), but should hopefully
# work on Linux and solaris (SunOS).

# Handle the LIBRARYNAME option - used when building libs...

# from being built for the library. This .o files may then be linked to by a
# tool if the tool does not need (or want) the semantics a .a file provides
# (linking in only object files that are "needed"). If a library is never to
# be used in this way, it is better to define DONT_BUILD_RELINKED, and define
# BUILD_ARCHIVE instead.
#
# Some libraries must be built as .a files (libscalar for example) because if
# it's built as a .o file, then all of the constituent .o files in it will be
# linked into tools (for example gccas) even if they only use one of the parts
# of it. For this reason, sometimes it's useful to use libraries as .a files.
