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 may be set by setting incoming variables:
10 # 1. LEVEL - The level of the current subdirectory from the top of the
11 # MagicStats view. This level should be expressed as a path, for
12 # example, ../.. for two levels deep.
14 # 2. DIRS - A list of subdirectories to be built. Fake targets are set up
15 # so that each of the targets "all", "install", and "clean" each build.
16 # the subdirectories before the local target.
18 # 3. Source - If specified, this sets the source code filenames. If this
19 # is not set, it defaults to be all of the .cpp, .c, .y, and .l files
20 # in the current directory. Also, if you want to build files in addition
21 # to the local files, you can use the ExtraSource variable
23 #===-----------------------------------------------------------------------====
25 # These are options that can either be enabled here, or can be enabled on the
26 # make command line (ie, make ENABLE_PROFILING=1)
29 # When ENABLE_PROFILING is enabled, the llvm source base is built with profile
30 # information to allow gprof to be used to get execution frequencies.
34 # When ENABLE_PURIFY is enabled, the LLVM tools are linked with purify (which
35 # must be locally installed) to allow for some automated memory error debugging.
39 # When ENABLE_OPTIMIZED is enabled, Release builds of all of the LLVM code are
40 # turned on, and Debug builds are turned off.
44 # If you do not want to build into /shared, uncomment this
49 # if SHARED_LIBRARY is specified, the default is to build the dynamic lib
53 # Default Rule: Make sure it's also a :: rule
56 # Default for install is to at least build everything...
60 # Figure out which directory to build stuff into. We want to build into the
61 # /shared directory by default because it is guaranteed to be local to the

179 # of it. For this reason, sometimes it's useful to use libraries as .a files.
