2021-03-29Fix RemoveAccesses, delete CSESubAccesses (#2157)Jack Koenig
CSESubAccesses was intended to be a simple workaround for a quadratic performance bug in RemoveAccesses but ended up having tricky corner cases and was hard to get right. The solution to the RemoveAccesses bug--quadratic expansion of dynamic indexes of vecs of aggreate type--turned out to be quite simple and makes CSESubAccesses much less useful and not worth fixing.

2020-05-01Add missing invalidations to some transforms (#1541)Schuyler Eldridge
This adds missing invalidations to four transforms: - ExpandConnects - RemoveAccesses - SplitExpressions - VerilogMemDelays This necessarily updates test cases which expect exact transform orders to reflect the new order.

2020-04-22Mixin DependencyAPIMigration to all TransformsSchuyler Eldridge
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.

2020-04-07Fix dynamic SubAccess of zero-length vectors (#1450)Albert Magyar
* Fix dynamic SubAccess of zero-length vectors * Fixes #230 * Add new ZeroLengthVecs pass that occurs before RemoveAccesses * Include this in stage.Forms.MidForm * Add to High->Mid order in compiler test based on @seldridge feedback * Use validif to produce out-of-bounds value in ZeroLengthVecs * Update scaladoc * Fix test imports

2019-03-26Convert the RemoveAccesses object into a class. (#1058)Jim Lawson
* Convert the RemoveAccesses object into a class. Prevent simultaneous access to common resources when tests are run in parallel. * Respond to comments - use object factory to preserve existing API.
2018-06-11Add utilities for UInt and SInt literals (#815)Jack Koenig
Also minor cleanup to literal construction in Visitor
2018-03-27Change throwInternalError to use a String instead of Option[String] (#777)Jack Koenig
2018-02-16Replacematcherror - catch exceptions and convert to internal error. (#424)Jim Lawson
* 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.
