data IdentifierSet

A collection of unique identifiers. Allows for fast fresh identifier generation.

NB: use the functions in Clash.Netlist.Id. Don't use the constructor directly.

Constructors

IdentifierSet

Fields

• is_allowEscaped :: !Bool

  Allow escaped ids? If set to False, "make" will always behave like "makeBasic".

• is_lowerCaseBasicIds :: !PreserveCase

  Force all generated basic identifiers to lowercase.

• is_hdl :: !HDL

  HDL to generate fresh identifiers for

• is_freshCache :: !FreshCache

  Maps an i_baseNameCaseFold to a map mapping the number of extensions (in i_extensionsRev) to the maximum word at that basename/level. For example, if a set would contain the identifiers:

  foo, foo_1, foo_2, bar_5, bar_7_8

  the map would look like:

  (foo, [(0, 0), (1, 2)

  ), (bar, [(1, 5), (2, 8)])]

  This mapping makes sure we can quickly generate fresh identifiers. For example, generating a new id for "foo_1" would be a matter of looking up the base name in this map, concluding that the maximum identifier with this basename and this number of extensions is "foo_2", subsequently generating "foo_3".

  Note that an identifier with no extensions is also stored in this map for practical purposes, but the maximum ext is invalid.

• is_store :: !(HashSet Identifier)

  Identifier store

data Identifier

HDL identifier. Consists of a base name and a number of extensions. An identifier with a base name of "foo" and a list of extensions [1, 2] will be rendered as "foo_1_2".

Note: The Eq instance of Identifier is case insensitive! E.g., two identifiers with base names fooBar and FoObAR are considered the same. However, identifiers are stored case preserving. This means Clash won't generate two identifiers with differing case, but it will try to keep capitalization.

The goal of this data structure is to greatly simplify how Clash deals with identifiers internally. Any Identifier should be trivially printable to any HDL.

NB: use the functions in Clash.Netlist.Id. Don't use these constructors directly.

Constructors

RawIdentifier

Unparsed identifier. Used for things such as port names, which should appear in the HDL exactly as the user specified.

Fields

• !Text

  An identifier exactly as given by the user

• (Maybe Identifier)

  Parsed version of raw identifier. Will not be populated if this identifier was created with an unsafe function.

• !CallStack

  Stores where this identifier was generated. Tracking is only enabled is debugIsOn, otherwise this field will be populated by an empty callstack.

UniqueIdentifier

Parsed and sanitized identifier. See various fields for more information on its invariants.

Fields

• i_baseName :: !Text

  Base name of identifier. make makes sure this field:

  • does not end in _num where num is a digit.
  • is solely made up of printable ASCII characters
  • has no leading or trailing whitespace
• i_baseNameCaseFold :: !Text

  Same as i_baseName, but can be used for equality testing that doesn't depend on capitalization.

• i_extensionsRev :: [Word]

  Extensions applied to base identifier. E.g., an identifier with a base name of foo and an extension of [6, 5] would render as foo_5_6. Note that extensions are stored in reverse order for easier manipulation.

• i_idType :: !IdentifierType

  See IdentifierType.

• i_hdl :: !HDL

  HDL this identifier is generated for.

• i_provenance :: !CallStack

  Stores where this identifier was generated. Tracking is only enabled is debugIsOn, otherwise this field will be populated by an empty callstack.

• _typeTranslator :: CustomReprs -> TyConMap -> Type -> State HWMap (Maybe (Either String FilteredHWType))

• _tcCache :: TyConMap

• _curCompNm :: !(Identifier, SrcSpan)
• _intWidth :: Int
• _seenIds :: IdentifierSet

  All names currently in scope.

• _seenComps :: IdentifierSet

  Components (to be) generated during this netlist run. This is always a subset of seenIds. Reason d'etre: we currently generate components in a top down manner. E.g. given:

  • A
  • - B
  • - C

  we would generate component A first. Before trying to generate B and C. A might introduce a number of signal declarations. The names of these signals can't clash with the name of component B, hence we need to pick a name for B unique w.r.t. all these signal names. If we would postpone generating a unqiue name for B til _after_ generating all the signal names, the signal names would get all the "nice" names. E.g., a signal would be called "foo", thereby forcing the component B to be called "foo_1". Ideally, we'd use the "nice" names for components, and the "ugly" names for signals. To achieve this, we generate all the component names up front and subsequently store them in _seenComps.

• _seenPrimitives :: Set Text

  Keeps track of invocations of ´mkPrimitive´. It is currently used to filter duplicate warning invocations for dubious blackbox instantiations, see GitHub pull request #286.
