Method Details

values

public static Opnd.MpIntToMpInt[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Opnd.MpIntToMpInt valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

convertOpndToOpnd

public <N extends Emitter.Next>
Opnd.OpndEm<JitType.MpIntJitType,N> convertOpndToOpnd(Emitter<N> em,
 Opnd<JitType.MpIntJitType> from,
 JitType.MpIntJitType to,
 Opnd.Ext ext,
 Scope scope)

Description copied from interface: Opnd.MpToMpConv

Convert an operand in locals to another in locals

NOTE: This may be accomplished in part be re-using legs from the source operand in the destination operand

Specified by:

convertOpndToOpnd in interface Opnd.MpToMpConv<Types.TInt,JitType.IntJitType,JitType.MpIntJitType,Types.TInt,JitType.IntJitType,JitType.MpIntJitType>

Type Parameters:

N - the tail of the stack (...)

Parameters:

em - the emitter

from - the source operand

to - the destination p-code type

ext - the kind of extension to apply

scope - a scope for generated temporary variables

Returns:

the resulting operand and emitter with ...

doGenArrExt

public static <N extends Emitter.Next> Emitter<N> doGenArrExt(Emitter<N> em,
 Local<Types.TRef<int[]>> arr,
 int legsOut,
 int defLegs,
 Opnd.Ext ext,
 Scope scope)

Emit code that extends a value to fill the rest of an array

For sign extension, this will assume the last filled element of the array so far is the leg having the sign bit. It shifts and extends that bit to fill a new temporary leg and uses it to fill the remaining more-significant legs. NOTE: legsOut may be less than the actual size of the array, since slack elements may have been allocated.

Type Parameters:

N - the tail of the stack (...)

Parameters:

em - the emitter

arr - a handle to the local containing the array

legsOut - the number of output legs

defLegs - the number of legs already filled

ext - the kind of extension to apply

scope - a scope for generated temporary variables

Returns:

the emitter with ...

convertOpndToArray

public <N extends Emitter.Next>
Emitter<Emitter.Ent<N,Types.TRef<int[]>>> convertOpndToArray(Emitter<N> em,
 Opnd<JitType.MpIntJitType> from,
 JitType.MpIntJitType to,
 Opnd.Ext ext,
 Scope scope,
 int slack)

Description copied from interface: Opnd.MpToMpConv

Convert an operand in locals to an array

Specified by:

convertOpndToArray in interface Opnd.MpToMpConv<Types.TInt,JitType.IntJitType,JitType.MpIntJitType,Types.TInt,JitType.IntJitType,JitType.MpIntJitType>

Type Parameters:

N - the tail of the stack (...)

Parameters:

em - the emitter

from - the source operand

to - the destination p-code type

ext - the kind of extension to apply

scope - a scope for generated temporary variables

slack - the number of extra (more significant) elements to allocate in the array

Returns:

the emitter with ..., arrayref
