2021-12-17Deprecate all mutable methods on RenameMap (#2444)Jack Koenig
* Add renamemap.MutableRenameMap which includes these methods without deprecation * Deprecate Stringly typed RenameMap APIs which were accidentally undeprecated a while ago Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
2020-12-15Improve performance of LowerTypes renaming (#2024)Jack Koenig
This is done by having LowerTypes uses two RenameMaps instead of one for each module. There is one for renaming instance paths, and one for renaming everything within modules. Also add some utilities: * TargetUtils for dealing with InstanceTargets * RenameMap.fromInstanceRenames

2020-08-12Combined Uniquify and LowerTypes pass (#1784)Kevin Laeufer
* 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
