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

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.

2019-10-18Upstream intervals (#870)Adam Izraelevitz
Major features: - Added Interval type, as well as PrimOps asInterval, clip, wrap, and sqz. - Changed PrimOp names: bpset -> setp, bpshl -> incp, bpshr -> decp - Refactored width/bound inferencer into a separate constraint solver - Added transforms to infer, trim, and remove interval bounds - Tests for said features Plan to be released with 1.3
