DottyPrimitives

dotty.tools.backend.jvm.DottyPrimitives

Scala primitive operations are represented as methods in Any and AnyVal subclasses. Here we demultiplex them by providing a mapping from their symbols to integers. Different methods exist for different value types, but with the same meaning (like plus, minus, etc.). They will all be mapped to the same int.

Note: The three equal methods have the following semantics:

"==" checks for null, and if non-null, calls java.lang.Object.equals (class: Any; modifier: final). Primitive: EQ
"eq" usual reference comparison (class: AnyRef; modifier: final). Primitive: ID
"equals" user-defined equality (Java semantics) (class: Object; modifier: none). Primitive: EQUALS

Inspired from the scalac compiler.

Concrete methods

Return the code for the given symbol.

Attributes

Return the primitive code of the given operation. If the operation is an array get/set, we inspect the type of the receiver to demux the operation.

Attributes

fun: The method symbol
tpe: The type of the receiver object. It is used only for array operations
