- 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

Gives all transform specs access to useful utilities (like dontTouch).
Deletes some duplicate code. Parsing mode UseInfo is fine for
everything, only matters if the test actually uses info.

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.

Jar resources (unlike classes) are typically not scoped. This can create collisions if we have similarly named resources in multiple jars, especially when merging multiple projects in an IDE. Give this resource a distinct name to avoid colliding with chisel3 top.cpp.

|
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.

Will place tests in ./test_run_dir/ instead of /tmp/

* Move BackendCompilationUtilities into a util package for use by chisel3.
Some of this could be moved into a more general tools package, but since chisel3 already has a dependency on firrtl ...
* Push util down into firrtl so as not to conflict with scala.util.
|
|
Also run CheckTypes after ExpandWhens
Fixes #330
|
|
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
|
|
* Transform Ids now handled by Class[_ <: Transform] instead of magic numbers
* Transforms define inputForm and outputForm
* Custom transforms can be inserted at runtime into compiler or the Driver
* Current "built-in" custom transforms handled via above mechanism
* Verilog-specific passes moved to the Verilog emitter
|
|
Change integration tests to be classes that extend abstract classes. This
allows them to be run in parallel. Also expand API to support Verilog
resources in integration tests.

Transforms are new unit of modularity within the compiler.

Including using different clocks and ports defined in when scope.
