Alexander Neundorf 39383ef8cb Major optimization of C/C++ dependency scanning.
Now only the dependencies for the file where the dependencies actually may
have changed are rescanned, before that this was done for all source files
even if only one source file had changed.
This reduces e.g. on my machine the time for scanning the dependencies
of kdelibs/khtml/ when only one file (khtml_global.cpp) has changed from
around 7.5 seconds to 1.2 seconds.

The tests succeed, it does what I expected it to do on kdelibs, and Brad
also reviewed the patch, so I think it should be ok.

Brad King 7652a8a1e5 ENH: Teach cmDependsC about user-configured macro transformations.
- Syntax is SOME_MACRO(%)=value-with-%
  - Later we will configure these with target and directory properties.
  - See issue #6648.

Brad King 6bba86c8c8 BUG: Patch from Alex to recompute dependencies when the include regex changes. This addresses bug#4168. 2007-02-05 09:48:38 -05:00
Brad King 6a347e9858 ENH: Patch from Alex to speed dependency scanning approximately 2x. 2006-09-13 12:43:32 -04:00
Brad King 409f70bc91 ENH: Make sure all custom command outputs are up to date before scanning dependencies. This avoids the need to pass a list of generated files to the dependency scanning code and to rescan after the files have been generated. Currently there is no notion of implicit dependencies of the custom commands themselves so this design is safe. We only need to make sure implicit dependencies are up to date before the make process for the /build part of a target is executed because only this process loads them. This is a step towards fixing bug#3658. 2006-08-31 14:09:56 -04:00
