[skip formal checks] LEC passes with Formality
* Improve code generation for smem RW-port wmode port
A common case for these port-enables is
wen = valid & write
ren = valid & !write
which the RW-port transform currently turns into
en = (valid & write) | (valid & !write)
wmode = valid & write
because it proved `wen` and `ren` are mutually exclusive via `write`.
Synthesis tools can trivially optimize `en` to `valid`, so that's not a
problem, but the wmode field can't be optimized if going into a black box.
This PR instead sets `wmode` to whatever node was used to prove
mutual exclusion, which is always a simpler expression. In this case:
en = (valid & write) | (valid & !write)
wmode = write
* In RemoveCHIRRTL, infer mask relative to port definition
Previously, it was inferred relative to the memory definition causing
the mask condition to be redundantly conjoined with the enable signal.
Also enable ReplSeqMems to ignore all ValidIfs (not just on Clocks) to
improve QoR.

- 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

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.

* Rename implict module "clk" input to "clock".
This doesn't rename all the "self-contained" test instances.
nor the memory "clk" enables,
nor the implict module "clk"s in the regress .fir files.
* Consistency: rename implict module "clk" input to "clock" in "self-contained" test instances.
This doesn't rename the memory "clk" enables, nor the implict module "clk"s in the regress .fir files.

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
|
|
* Keep package name + directory structure consistent
This annoyed me so heres a PR
* fix InferReadWrite references
* delete .ConvertFixedToSInt.scala.swo
