| michael@0 | 9 | # Building XPIDLs effectively consists of two steps: |
| michael@0 | 10 | # |
| michael@0 | 11 | # 1) Staging all .idl files to a common directory. |
| michael@0 | 12 | # 2) Doing everything with the .idl files. |
| michael@0 | 13 | # |
| michael@0 | 14 | # Each .idl file is processed into a .h file and typelib information. |
| michael@0 | 15 | # The .h file shares the same stem as the input file and is installed |
| michael@0 | 16 | # in the common headers include directory. |
| michael@0 | 17 | # |
| michael@0 | 18 | # XPIDL files are logically grouped together by modules. The typelib |
| michael@0 | 19 | # information for all XPIDLs in the same module is linked together into |
| michael@0 | 20 | # an .xpt file having the name of the module. |
| michael@0 | 21 | # |
| michael@0 | 22 | # As an optimization to reduce overall CPU usage, we process all .idl |
| michael@0 | 23 | # belonging to a module with a single command invocation. This prevents |
| michael@0 | 24 | # redundant parsing of .idl files and significantly reduces CPU cycles. |
| michael@0 | 25 | # |
| michael@0 | 26 | # Future improvement: Headers are currently written to a local directory then |
| michael@0 | 27 | # installed in the distribution directory. It is preferable to write headers |
| michael@0 | 28 | # directly into the distribution directory. However, PGO builds remove the dist |
| michael@0 | 29 | # directory via rm -rf (with no regards to manifests). Since the cost of |
| michael@0 | 30 | # processing XPIDL files is not trivial, it is preferrable to cache the headers |
| michael@0 | 31 | # and reinstall them rather than regenerate them. Ideally the dist pruning is |
| michael@0 | 32 | # performed with manifests. At that time we can write headers directly to the |
| michael@0 | 33 | # dist directory. |
