Bumping Scala minor version but not bumping CI guards on the version
causes tests to no longer run. Change to using startsWith(...) so that
minor version bumps won't cause issues in the future.
Also run ScalaFmt

* Utils: add to_dir helper function
* firrt.SymbolTable trait for scanning declarations
* ir: RefLikeExpression trait to represent SubField, SubIndex, SubAccess and Reference nodes
* add new implementation of the LowerTypes pass
* replace LowerTypes with NewLowerTypes
* remove dependencies on Uniquify
* GroupComponentSpec: GroupComponents is run before lower types
* NewLowerTypes: address Adam's suggestions
* LoweringCompilerSpec: Uniquify was removed and NewLowerTypes
* LowerTypesSpec: add newline at the end of file
* LowerTypesSpec: port Uniquify tests to combined pass
* NewLowerTypes: ensure that internal methods are not visible
* NewLowerTypes: extend DependencyAPIMigration
* NewLowerTypes: lower ports without looking at the body
* LowerTypesSpec: use TransformManager instead of hard coded passes.
* NewLowerTypes: names are already assumed to be part of the namespace
* LowerTypesSpec: test name clashes between ports and nodes, inst, mem
* NewLowerTypes: correctly rename nodes, mems and instances that clash with port names
* NewLowerTypes: Iterable[String] instead of Seq[String] for 2.13
* NewLowerTypes: add a fast path for ground types without renaming
* LowerTypesSpec: remove trailing commans for 2.11
* LowerTypesSpec: explain why there are two
* Uniquify: use loweredName from NewLowerType
* replace old LowerTypes pass with NewLowerTypes pass
* Uniquify: deprecate pass usage
There are some functions that are still used by other passes.
* LowerTypes: InstanceKeyGraph now has a private constructor
* LowerTypes: remove remaining references to NewLowerTypes
* LoweringCompilerSpec: fix transform order to LowerTypes
* SymbolTable: add improvements from PR
* LoweringCompilerSpec: ignore failing CustomTransform tests

* Add assume, assert, cover statements
* Assert submodule assumptions
* Add warning when removing verification statements
* Remove System Verilog behaviour emitter warning
* Add option to disable AssertSubmoduleAssumptions
* Document verification statements in the spec
The syntax for the new statements is
assert(clk, cond, en, msg)
assume(clk, cond, en, msg)
cover(clk, cond, en, msg)
With assert as a representative example, the semantics is as follows:
`clk` is the clock, `cond` is the expression being asserted, `en` is the
enable signal (if `en` is low then the assert is not checked) and `msg`
is a string message intended to be reported as an error message by the
model checker if the assertion fails.
In the Verilog emitter, the new statements are handled by a new
`formals` map, which groups the statements by clock domain. All model
checking statements are then emitted within the context of an `ifdef
FORMAL` block, which allows model checking tools (like Symbiyosys) to
utilize the statements while keeping them out of synthesis flows.

Also add tests for what should happen to 'is invalid' in ExpandWhens
Fixes #606

* Added pass name to debug logger
* Addresses #459. Rewords transform annotations API.
Now, any annotation not propagated by a transform is considered deleted.
A new DeletedAnnotation is added in place of it.
* Added more stylized debugging style
* WIP: make pass transform
* WIP: All tests pass, need to pull master
* Cleaned up PR
* Added rename updates to all core transforms
* Added more rename tests, and bugfixes
* Renaming tracks non-leaf subfields
E.g. given:
wire x: {a: UInt<1>, b: UInt<1>[2]}
Annotating x.b will eventually annotate x_b_0 and x_b_1
* Bugfix instance rename lowering broken
* Address review comments
* Remove check for seqTransform, UnknownForm too restrictive check

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.
