Enum Class DoubleAccessGen

java.lang.Object

java.lang.Enum<DoubleAccessGen>

ghidra.pcode.emu.jit.gen.access.DoubleAccessGen

All Implemented Interfaces:

AccessGen<JitType.DoubleJitType>, SimpleAccessGen<Types.TDouble,JitType.DoubleJitType>, Serializable, Comparable<DoubleAccessGen>, Constable

public enum DoubleAccessGen
extends Enum<DoubleAccessGen>
implements SimpleAccessGen<Types.TDouble,JitType.DoubleJitType>

The generator for accessing doubles

This is accomplished by delegating to the long access generator with type conversion.

public static final DoubleAccessGen BE

The big-endian instance

LE

public static final DoubleAccessGen LE

The little-endian instance

Method Details

values

public static DoubleAccessGen[] 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 DoubleAccessGen 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

genReadToStack

public <THIS extends JitCompiledPassage,
N extends Emitter.Next>
Emitter<Emitter.Ent<N,Types.TDouble>> genReadToStack(Emitter<N> em,
 Local<Types.TRef<THIS>> localThis,
 JitCodeGenerator<THIS> gen,
 Varnode vn)

Description copied from interface: SimpleAccessGen

Emit code to read a varnode

If the varnode fits completely in the block (the common case), then this accesses the bytes from the one block, using the method chosen by size. If the varnode extends into the next block, then this will split the varnode into two portions according to machine byte order. Each portion is accessed using the method for the size of that portion. The results are reassembled into a single operand.

Specified by:

genReadToStack in interface SimpleAccessGen<Types.TDouble,JitType.DoubleJitType>

Type Parameters:

N - the incoming stack

Parameters:

em - the emitter typed with the incoming stack

localThis - a handle to the local holding the this reference

gen - the code generator

vn - the varnode

Returns:

the code generator with the resulting stack, i.e., having pushed the value

genWriteFromStack

public <THIS extends JitCompiledPassage,
N1 extends Emitter.Next,
N0 extends Emitter.Ent<N1,
Types.TDouble>>
Emitter<N1> genWriteFromStack(Emitter<N0> em,
 Local<Types.TRef<THIS>> localThis,
 JitCodeGenerator<THIS> gen,
 Varnode vn)

Description copied from interface: SimpleAccessGen

Emit code to write a varnode

If the varnode fits completely in the block (the common case), then this accesses the bytes from the one block, using the method chosen by size. If the varnode extends into the next block, then this will split the varnode into two portions according to machine byte order. Each portion is accessed using the method for the size of that portion.

Specified by:

genWriteFromStack in interface SimpleAccessGen<Types.TDouble,JitType.DoubleJitType>

Type Parameters:

N1 - the tail of the incoming stack

N0 - the incoming stack having the value on top

Parameters:

em - the emitter typed with the incoming stack

localThis - a handle to the local holding the this reference

gen - the code generator

vn - the varnode

Returns:

the code generator with the resulting stack, i.e., having popped the value
