Description
Expand "memory" function to placeholder.
This parser replaces functions of the form (memory[NBYTES] ADDRESS) to placeholders that are later substituted with the actual value read from ROSE's semantic memory state.

Property: Semantic state used during delayed expansion.
This property holds a pointer to the semantic operators and its current state that's used during the second phase of expansion (delayedExpansion).
Definition at line 394 of file SymbolicExpressionParser.h.
◆ riscOperators() [2/2]
|
inline |
Property: Semantic state used during delayed expansion.
This property holds a pointer to the semantic operators and its current state that's used during the second phase of expansion (delayedExpansion).

◆ immediateExpansion()
|
overridevirtual |
Operator to expand a list into an expression tree.
The width in bits is either the width specified in square brackets for the function symbol, or zero. Functors are all called for each symbol, and the first one to return non-null is the one that's used to generate the symbolic expression.
Implements Rose::BinaryAnalysis::SymbolicExpressionParser::OperatorExpansion.
◆ delayedExpansion()
|
overridevirtual |
Substitute one expression with another.
This second phase of expansion occurs after parsing (perhaps much later) and is able to dynamically replace the given expression with some other expression. For instance, if this object recognizes register names, it it might replace the register names with variables in the first phase, and during the second phase read register values from a provided state.
If the input expression does not need to be substituted, then this function should return the original expression.
Reimplemented from Rose::BinaryAnalysis::SymbolicExpressionParser::Expansion.
