1 #===-- Makefile.common - Common make rules for LLVM -------*- makefile -*--====
3 # This file is included by all of the LLVM makefiles. This file defines common
4 # rules to do things like compile a .cpp file or generate dependancy info.
5 # These are platform dependant, so this is the file used to specify these
6 # system dependant operations.
8 # The following functionality can be set by setting incoming variables.
9 # The variable $(LEVEL) *must* be set:
11 # 1. LEVEL - The level of the current subdirectory from the top of the
12 # MagicStats view. This level should be expressed as a path, for
13 # example, ../.. for two levels deep.
15 # 2. DIRS - A list of subdirectories to be built. Fake targets are set up
16 # so that each of the targets "all", "install", and "clean" each build
17 # the subdirectories before the local target. DIRS are guaranteed to be
20 # 3. PARALLEL_DIRS - A list of subdirectories to be built, but that may be
21 # built in any order. All DIRS are built in order before PARALLEL_DIRS are
22 # built, which are then built in any order.
24 # 4. Source - If specified, this sets the source code filenames. If this
25 # is not set, it defaults to be all of the .cpp, .c, .y, and .l files
26 # in the current directory. Also, if you want to build files in addition
27 # to the local files, you can use the ExtraSource variable

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