#===-- 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.
