	* Add sbt-scalafix * Add scalafix guide to README * Remove Unused Import * Remove deprecated procedure syntax
2018-10-30	Instance Annotations (#926)	Adam Izraelevitz
	Formerly #865 Major Code Changes/Features Added: Added Target trait as replacement for Named Added TargetToken as token in building Target Added GenericTarget as a catch-all Target Added CircuitTarget, ModuleTarget, ReferenceTarget, and InstanceTarget Added ResolvePaths annotation Added EliminateTargetPaths (and helper class DuplicationHelper) Updated Dedup to work with instance annotations Updated RenameMap to work with instance annotations DCE & ConstantProp extend ResolveAnnotationPaths
2018-10-27	Revert "Instance Annotations (#865)" (#925)	Adam Izraelevitz
	This reverts commit 7e2f787e125227dc389d5cf1d09717748ecfed2e.
2018-10-24	Instance Annotations (#865)	Adam Izraelevitz
	Added Target, which now supports Instance Annotations. See #865 for details.
2018-08-24	Update DontTouchAnnotation not found error message (#864)	Jack Koenig

2018-02-27	Refactor Annotations (#721)	Jack Koenig
	- Old Annotation renamed to deprecated LegacyAnnotation - Annotation is now a trait that can be extended - New JsonProtocol for Annotation [de]serialization - Replace AnnotationMap with AnnotationSeq - Deprecate Transform.getMyAnnotations - Update Transforms - Turn on deprecation warnings - Remove deprecated Driver.compile - Make AnnotationTests abstract with Legacy and Json subclasses - Add functionality to convert LegacyAnnotations of built-in annos This will give a noisy warning and is more of a best effort than a robust solution. Fixes #475 Closes #609
2017-06-21	Add --no-dce command-line option to skip DCE	Jack Koenig

2017-05-11	Improved Global Dead Code Elimination (#549)	Jack Koenig
	Performs DCE by constructing a global dependency graph starting with top-level outputs, external module ports, and simulation constructs as circuit sinks. External modules can optionally be eligible for DCE via the OptimizableExtModuleAnnotation. Dead code is eliminated across module boundaries. Wires, ports, registers, and memories are all eligible for removal. Components marked with a DontTouchAnnotation will be treated as a circuit sink and thus anything that drives such a marked component will NOT be removed. This transform preserves deduplication. All instances of a given DefModule are treated as the same individual module. Thus, while certain instances may have dead code due to the circumstances of their instantiation in their parent module, they will still not be removed. To remove such modules, use the NoDedupAnnotation to prevent deduplication.
