| 2 | # |
| 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. |
| 7 | # |
| 8 | # The following functionality may be set by setting incoming variables: |
| 9 | # |
| 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. |
| 13 | # |
| 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. |
| 17 | # |
| 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. |
| 21 | # |
| 22 | |
| 23 | # Default Rule: |
| 24 | all :: |
| 25 | |
| 26 | # Default for install is to at least build everything... |
| 27 | install :: |
