It would replace them with a validif node with a UIntLiteral which can
lead to type errors.

This mixes in the new DependencyAPIMigration trait into all Transforms
and Passes. This enables in-tree transforms/passes to build without
deprecation warnings associated with the deprecated CircuitForm.
As a consequence of this, every Transform now has UnknownForm as both
its inputForm and outputForm. This PR modifies legacy Compiler and
testing infrastructure to schedule transforms NOT using
mergeTransforms/getLoweringTransforms (which rely on inputForm and
outputForm not being UnknownForm), but instead using the Dependency
API.

Moved from RemoveValidIf
Also Make RemoveValidIf.getGroundZero public and support Fixed

* Catch exceptions and convert to internal error.
We need to update the displayed message to incorporate a line number and text to be used for the issue.
* Cleanup exception handling/throwing.
Re-throw expected (or uncorrectable exceptions).
Provide Utils.getThrowable() to get the first (eldest) or last throwable in the chain.
Update tests to conform to FreeSpec protocol.
* Minor cleanup
Admit we've updated some deprecated ScalaTest methods.

Replace with more sensible comment to see LICENSE rather than including the

if methods has parens, then referencing without parens
is a method value, you don't need following underscore

Changed code from match statements in Mappers.scala to methods on the various
IR classes. This allows custom IR nodes to implement the mapper functions and
thus work (ie. not match error) when map is called on them.
This also should have a marginal performance increase because of use of virtual
function calls rather than match statements.

trait AST -> abstract class FirrtlNode
Move all IR to new package ir
Add import of firrtl.ir._
|
|
trait Stmt -> abstract class Statement (to match Expression)
abbrev. exp -> expr
BulkConnect -> PartialConnect
camelCase things that were snake_case
case class Empty() -> case object EmptyStmt
Change >120 character Statements to multiline
|
|
trait Module -> abstract class DefModule
InModule -> Module (match concrete syntax)
ExModule -> ExtModule (match concrete syntax)
Add simple scaladoc for each one

This is to start moving stuff out of Emitter and into separate passes
