Class AssemblyOperandState

java.lang.Object

ghidra.app.plugin.assembler.sleigh.sem.AbstractAssemblyState

ghidra.app.plugin.assembler.sleigh.sem.AssemblyOperandState

public class AssemblyOperandState
extends AbstractAssemblyState

The state corresponding to a non-sub-table operand

This is roughly analogous to ConstructState, but for assembly. However, it also records the value of the operand and the actual operand symbol whose value it specifies.

Constructor Details

AssemblyOperandState

public AssemblyOperandState(AbstractAssemblyTreeResolver<?> resolver,
 List<AssemblyConstructorSemantic> path,
 int shift,
 AssemblyTerminal terminal,
 long value,
 OperandSymbol opSym)

Construct the state for a given operand and selected value

Parameters:

resolver - the resolver

path - the path for diagnostics

shift - the (right) shift of this operand

terminal - the terminal that generated this state

value - the value of the operand

opSym - the operand symbol

Method Details

computeHash

public int computeHash()

Description copied from class: AbstractAssemblyState

Pre compute this nodes hash

Specified by:

computeHash in class AbstractAssemblyState

Returns:

the hash

partsEqual

protected boolean partsEqual(AssemblyOperandState that)

equals

public boolean equals(Object obj)

Specified by:

equals in class AbstractAssemblyState

toString

public String toString()

Overrides:

toString in class Object

computeBitsize

protected int computeBitsize()

Compute the size in bits of this operand's value

If this operand does not have a strict size, 0 is returned.

Returns:

the size

solveNumeric

protected AssemblyResolution solveNumeric()

Solve the operand's defining expression set equal to the desired value

Returns:

the resolved patterns, an error, or a backfill

resolve

protected Stream<AssemblyResolvedPatterns> resolve(AssemblyResolvedPatterns fromRight,
 Collection<AssemblyResolvedError> errors)

Description copied from class: AbstractAssemblyState

Generate machine (partial) code for this node

Specified by:

resolve in class AbstractAssemblyState

Parameters:

fromRight - the accumulated patterns thus far, from the right sibling or left-most child

errors - a place to collect error reports

Returns:

the stream of generated patterns, as accumulated

getTerminal

public AssemblyTerminal getTerminal()

getValue

public long getValue()

getOperandSymbol

public OperandSymbol getOperandSymbol()
