Reimplemented from Rose::BinaryAnalysis::InstructionSemantics::SymbolicSemantics::RiscOperators.

overridevirtual |
Virtual allocating constructor.
The protoval
is a prototypical semantic value that is used as a factory to create additional values as necessary via its virtual constructors. The state upon which the RISC operations operate must be set by modifying the currentState property. An optional SMT solver may be specified (see solver).
Reimplemented from Rose::BinaryAnalysis::InstructionSemantics::SymbolicSemantics::RiscOperators.

overridevirtual |
Virtual allocating constructor.
The supplied state
is that upon which the RISC operations operate and is also used to define the prototypical semantic value. Other states can be supplied by setting currentState. The prototypical semantic value is used as a factory to create additional values as necessary via its virtual constructors. An optional SMT solver may be specified (see solver).

Run-time promotion of a base RiscOperators pointer to our operators.
This is a checked conversion–it will fail if x
does not point to our object.
|
overridevirtual |
Called at the beginning of every instruction.
This method is invoked every time the translation object begins processing an instruction. Some policies use this to update a pointer to the current instruction.
