Class StartInstructionValueSolver
java.lang.Object
ghidra.app.plugin.assembler.sleigh.expr.AbstractExpressionSolver<StartInstructionValue>
ghidra.app.plugin.assembler.sleigh.expr.StartInstructionValueSolver
"Solves" expression of
inst_start
Works like the constant solver, but takes the value of inst_start
, which is given by the
assembly address.

solve
public AssemblyResolution solve(AbstractAssemblyResolutionFactory<?, ?> factory, StartInstructionValue iv, MaskedLong goal, Map<String, Long> vals, AssemblyResolvedPatterns cur, Set<SolverHint> hints, String description) Description copied from class:AbstractExpressionSolver
Attempt to solve an expression for a given value- Specified by:
solve
in classAbstractExpressionSolver<StartInstructionValue>
- Parameters:
iv
- the expression to solvegoal
- the desired value of the expressionvals
- values of defined symbolshints
- describes techniques applied by calling solversdescription
- the description to give to resolved solutions- Returns:
- the resolution
-
getValue
public MaskedLong getValue(StartInstructionValue iv, Map<String, Long> vals, AssemblyResolvedPatterns cur) Description copied from class:AbstractExpressionSolver
Attempt to get a constant value for the expression- Specified by:
getValue
in classAbstractExpressionSolver<StartInstructionValue>
- Parameters:
iv
- the expressionvals
- values of defined symbols- Returns:
- the constant value, or null if it depends on a variable
-
getInstructionLength
Description copied from class:AbstractExpressionSolver
Determines the length of the subconstructor that would be returned had the expression not depended on an undefined symbol.This is used by the backfilling process to ensure values are written to the correct offset
- Specified by:
getInstructionLength
in classAbstractExpressionSolver<StartInstructionValue>
- Parameters:
exp
- the expression- Returns:
- the length of filled in token field(s).
-
valueForResolution
public MaskedLong valueForResolution(StartInstructionValue exp, Map<String, Long> vals, AssemblyResolvedPatterns rc) Description copied from class:AbstractExpressionSolver
Compute the value of the expression given the (possibly-intermediate) resolution- Specified by:
valueForResolution
in classAbstractExpressionSolver<StartInstructionValue>
- Parameters:
exp
- the expression to evaluatevals
- values of defined symbolsrc
- the resolution on which to evaluate it- Returns:
- the result
