* Use signed output in LargeParamExecutionTest
Change the Verilog used in LargeParamExecutionTest to match its
ExtModule specification. An ExtModule with an SInt port should map to
a separate Verilog module with a signed port and this is disjoint from
an ExtModule with a UInt port.

* Error on ExtModules w/ same defname, diff. ports
Adds a high form check to ensure that external modules that have the
same defname also have exactly the same ports.

If a module has ports of type Bundle that are used in aggregate
connections in parent modules, Dedup cannot change the names of the
fields of the Bundle or it would change the semantics of the connection.
Dedup now detects this case and refrains from agnostifying the ports of
such modules to prevent this issue.

- RenameMap Behavior
-- Prevent transitive renaming A -> B -> C (continueRenaming)
-- Prevent transitive renaming for self-renames
- Target
-- Override toString as serialize for CompleteTarget
-- Expansion of stripHierarchy to enable stripping InstanceTargets to become ModuleTargets
Annotations
-- Bugfix in extractComponents where Products were not iterated over
-- Converts renamed targets to local targets using Target.referringModule to preserve sticky behavior
- Eliminate Target Paths
-- Make DuplicationHelper use LinkedHashMap, as we iterate over its contents and convert to Seq in def makePathless
-- Add DupedResult to map original module to new module targets
-- Update renaming to record a map from all relative instance paths to original module, to new module target
-- Consumes DedupedResult to give better name to new duplicated module if it was originally deduplicated
-- Reorder modules in attempt to preserve original ordering, pre-deduplication
-- Move utility functions to object
-- Bugfix: add self-renames to prevent ofModule _ of target _ cannot be renamed to Vector(_, _, _, ...) errors
- Dedup
-- Changed NoDedupAnnotation to contain ModuleTarget, rather than ModuleName
-- Added DedupedResult to map original module to the duplicate module
-- Consumes DupedResult to pick better name, if it existed
-- Updates renaming to chain the following: instancify deduped modules, remap differently named internal signals, then remap AST modules
-- Move utility functions to object
-- Remove annotations as part of determination of dedup correctness
-- Bugfix: add instance renames so that deduped modules have their instances properly renamed
- Dead Code Elimination
-- Add deletion of ASTModules
- Tests
-- Morphism Spec to ensure Dedup -> EliminateTargetPaths and EliminateTargetPaths -> Dedup patterns work properly
-- Update existing tests to make sure they work properly
-- Add Dedup tests to demonstrate instance renaming bug, EliminateTargetPaths for ofModule rename bug, and update RenameMap tests

* Add --nodedup option to facilitate FIRRTL to verilog regression testing.
* Short-circuit the DedupModules transform if NoCircuitDedupAnnotation exists.

Iterating on a HashSet could cause identical modules (including
annotations) to not dedup

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
|
|
This reverts commit 7e2f787e125227dc389d5cf1d09717748ecfed2e.

Added Target, which now supports Instance Annotations. See #865 for details.
|
|
|
|
* Added grouping pass
* Added InfoMagnet and infomappers
* Changed return type of execute to allow final CircuitState inspection
* Updated dedup. Now is name-agnostic
* Added GroupAndDedup transform

- 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

This makes it more concise to write tests

Changes Emitters to also be Transforms and use Annotations for both
telling an emitter to do emission as well as getting the emitted result.
Helper functions ease the use of the new interface. Also adds a
FirrtlExecutionOptions field as well as a command-line option. Use of
Writers in Compilers and Emitters is now deprecated.

|
|
FileInfo is merged
|
|
Restricts annotations to be string-based (and thus less typesafe)
Makes annotations more easily serializable and interact with Chisel
|
|
Replace with more sensible comment to see LICENSE rather than including the
whole license in every file
