Details

Testcase: 1. Create a compiler error somewhere (for example in layout/) 2. Build from toplevel (because there are things after layout/ that will need to get built too) 3. Wait for a long time until layout/ finally starts building 4. Encounter a new error, and go to step #1 It would be nice if there was a way to skip directly to the right tier in the build process, if you *know* for sure nothing before it had changed. If you wanted to be fancy, a script could even scan for the last-modified date of all modules before every build, compare it to the last-built date, and see where it needs to start building.
You mean something other than "make tier_9"? Calculating dependencies is tricky business, and I'm not sure additional complexity is called for here (instead of educating builders to rebuild only what they need to).
This bug / feature request is no longer compatible with the existing build system design.
