Implement compressed Namespace (backport #2856) (#2860)

2022-11-29T17:24:38+00:00

* Implement compressed Namespace (#2856)

The namespace disambiguates requests for the same name with _.
Rather than storing every disambiguated name in the underlying HashMap,
it now only stores the base along with the "next available" index. This
makes the logic for checking if a name is already contained in the
namespace slightly more sophisticated because users can name things in a
way that will collide with disambiguated names from a common substring.

For example, in naming the sequence "foo", "foo", "foo_1", the 2nd "foo"
takes the name "foo_1" so the following "foo_1" gets disambiguated to
"foo_1_1". But since we compressed that original "foo_1" into the same
HashMap entry as just "foo", we have to do a form of "prefix checking"
whenever naming something that ends in "_".

In practice, the saved memory allocations more than make up for the more
complicated logic to disambiguate names because the common case is still
fast.

Add Driver Compatibility Layer

2019-05-22T20:17:17+00:00

This includes phases necessary to provide backwards compatibility with
the old Chisel3 Driver. These are placed in a DriverCompatibility
object inside chisel3.stage.phases. The following four phases are
included:
  - AddImplicitOutputFile (from a TopNameAnnotation)
  - AddImplicitOutputAnnotationFile phase
  - DisableFirrtlStage (to disable ChiselStage running FirrtlStage)
  - MutateOptionsManager (to update options after ChiselStage)
  - ReEnableFirrtlStage (to renable FirrtlStage if needed)

Additionally, this adds a view of a ChiselExecutionResult for
providing the legacy return type of the Chisel Driver.
