def emitConvert(input: LoweredValue, outputRepresentation: LoweredValueRepresentation, pos: SIRPosition)(using lctx: LoweringContext): LoweredValue

Outbound conversions from a list-shaped value (Phase 5). The receiver this is the source emitter — SumBuiltinListEmitter(elemRepr) for cons-list sources, SumPairBuiltinListEmitter for pair-list sources.

Body lifted from SumDispatch.sumListCommonImpl: the previous gen parameter is now this. Targets covered: SumBuiltinList variants, PackedSumDataList, SumPairBuiltinList variants, SumDataAssocMap, plus cross-class delegations for SumUplcConstr / ProdUplcConstr / SumReprProxy and the PairIntDataList rebuild path.

override def genConstrLowered(constr: Constr, loweredArgs: List[LoweredValue], optTargetType: Option[SIRType])(using lctx: LoweringContext): LoweredValue

Generate constructor for this type — the workhorse, takes pre-lowered arguments. Implementations override this. Always called on DataDecl.tp (or a more specific case-class type for Sum→Product dispatch).

Value parameters

constr
  • constructor SIR node (carries name, decl, parentTypeArgs, anns, tp)
loweredArgs
  • already-lowered constructor arguments, in declaration order. Length matches constr.args.
optTargetType
  • optional target type (e.g., for Nil typing where the constr's declared tp is List[Nothing]).

Inherited methods

final def genConstr(constr: Constr, optTargetType: Option[SIRType] = ...)(using lctx: LoweringContext): LoweredValue

Convenience entry point — pre-lowers constr.args and delegates to genConstrLowered. Use this when the caller hasn't already lowered the arguments; callers that have pre-lowered arguments (like the main lowering driver) should call genConstrLowered directly to avoid double-lowering. Marked final so all dispatch decisions live in genConstrLowered and its overrides.

def defaultTypeVarReperesentation(tp: SIRType)(using LoweringContext): LoweredValueRepresentation

Get default representation for type variable. This representation is used when converting to parameters of scala functions with type parameters. (Usually the same as defaultDataRepresentation, except Lambdas).
