Modifier and Type	Method and Description
Instr	cloneForBlockCloning(InlinerInfo ii) Clone the instruction so it can be used in a cloned block which is present in a scope that itself or an ancestor scope (in the case of nested blocks) is being inlined.
Instr	cloneForInlining(InlinerInfo ii) Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope).

Method Detail

getOperands

public Operand[] getOperands()

cloneForInlining

public Instr cloneForInlining(InlinerInfo ii)

Description copied from class: Instr

Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope). This requires renaming variables and labels to eliminate naming conflicts.

Overrides:

cloneForInlining in class Instr

Parameters:

ii - This object manages renaming of variables and labels, handles args and return values.

Returns:

a new instruction that can be used in the target scope.

cloneForBlockCloning

public Instr cloneForBlockCloning(InlinerInfo ii)

Description copied from class: Instr

Clone the instruction so it can be used in a cloned block which is present in a scope that itself or an ancestor scope (in the case of nested blocks) is being inlined. This requires renaming variables to eliminate naming conflicts. Labels need not be renamed.

Overrides:

cloneForBlockCloning in class Instr

Returns:

a new instruction that can be used in the target scope.

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
