Class FusedInstructionPrototype

A prototype for a fused instruction: a special composite instruction that is entirely equivalent to a sequence of core instructions. Fused instructions are mostly useful for making back-ends emit better code.

Syntax

public abstract class FusedInstructionPrototype : InstructionPrototype

Constructors

FusedInstructionPrototype()

Creates a fused instruction prototype.

Declaration

public FusedInstructionPrototype()

Properties

ResultType

Gets the type of value produced instantiations of this prototype.

Declaration

public override sealed IType ResultType { get; }

Property Value

Type	Description
IType	A type of value.

Overrides

InstructionPrototype.ResultType

Methods

CheckConformance(Instruction, MethodBody)

Checks if a particular instance of this prototype conforms to the rules for this instruction prototype.

Declaration

public override IReadOnlyList<string> CheckConformance(Instruction instance, MethodBody body)

Parameters

Type	Name	Description
Instruction	instance	An instance of this prototype.
MethodBody	body	The method body that defines the instruction.

Returns

Type	Description
System.Collections.Generic.IReadOnlyList<System.String>	A list of conformance errors in the instruction.

Overrides

InstructionPrototype.CheckConformance(Instruction, MethodBody)

Expand(NamedInstructionBuilder)

Expands this fused instruction to an equivalent nonempty sequence of core instructions. The instance itself must be replaced by another instruction. Instruction expansion must be formulaic: it cannot depend on the rest of the control-flow graph.

Declaration

public abstract void Expand(NamedInstructionBuilder instance)

Parameters

Type	Name	Description
NamedInstructionBuilder	instance	An instance of this prototype to expand.
