static RiscOperatorsPtr Rose::BinaryAnalysis::InstructionSemantics2::NativeSemantics::RiscOperators::instance ( const BaseSemantics::SValuePtr protoval,
const Debugger::Ptr process 
)
inlinestatic

Instantiate a new RiscOperators object.

The register state, memory state, and combined state are instantiations of NativeSemantics RegisterState, MemoryState, and State, which point to the subordinate process and which are not copyable.

Definition at line 328 of file NativeSemantics.h.

static RiscOperatorsPtr Rose::BinaryAnalysis::InstructionSemantics2::NativeSemantics::RiscOperators::instance ( const BaseSemantics::StatePtr state)
inlinestatic

Instantiate a new RiscOperators object.

The state (registers and memory) for this object is provided by the caller and must be an instance of the NativeSemantics State that points to NativeSemantics RegisterState and MemoryState. User-defined subclasses can also be used.

Definition at line 340 of file NativeSemantics.h.

virtual BaseSemantics::RiscOperatorsPtr Rose::BinaryAnalysis::InstructionSemantics2::NativeSemantics::RiscOperators::create ( const BaseSemantics::SValuePtr protoval,
const SmtSolverPtr solver = SmtSolverPtr() 
) const
inlinevirtual

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::InstructionSemantics2::ConcreteSemantics::RiscOperators.

static RiscOperatorsPtr Rose::BinaryAnalysis::InstructionSemantics2::NativeSemantics::RiscOperators::promote ( const BaseSemantics::RiscOperatorsPtr x)
inlinestatic

Run-time promotion of a base object to a NativeSemantics RiscOperators.

This is a checked conversion–it will fail if x does not point to a NativeSemantics::RiscOperators object.
