Subject: [PATCH 14/23] Split up huge Top module into smaller modules.
|
2019-05-07 07:25:55 +00:00
|
|
|
|
|
|
|
|
This change is hopefully pure refactoring, splitting up the very large
|
|
|
|
|
and highly interlinked module into more manageable modules with
|
|
|
|
|
well-defined (or at least *better*-defined) interfaces between them.
