| #===-- 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. |
| # |
| # 3. 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 |

| # (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. |
