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).

Property: Show only operations for instructions.

Operators are usually called to interpret an instruction, but they can also be called directly by analysis, such as when an analysis needs to read a register from a semantic state. If the onlyInstructions property is set, then the output will show only operations that are associated with an instruction and will suppress operations that are invoked without a current instruction.

Property: Satisfiability module theory (SMT) solver.

This property holds a pointer to the satisfiability modulo theory (SMT) solver to use for certain operations. An SMT solver is optional and not all semantic domains will make use of a solver. Domains that use a solver will fall back to naive implementations when a solver is not available (for instance, equality of two values might be checked by looking at whether the values are identical).

◆ currentState() [1/2]

virtual BaseSemantics::StatePtr Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::currentState ( ) const

overridevirtual

Property: Current semantic state.

This is the state upon which the RISC operations operate. The state need not be set until the first instruction is executed (and even then, some RISC operations don't need any machine state; typically, only register and memory read and write operators need state). Different state objects can be swapped in at pretty much any time. Modifying the state has no effect on this object's prototypical value which was initialized by the constructor; new states should have a prototyipcal value of the same dynamic type.

◆ isNoopRead() [1/2]

virtual bool Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::isNoopRead ( ) const

overridevirtual

Property: No-op read.

This property can be set to indicate that the next read operation(s) are part of a possible read-then-write no-op sequence. This property is normally reset at the beginning and end of each instruction by startInstruction and finishInstruction.

For example, most ARM AArch32 A32 instructions are conditionally executed. Therefore any instruction that writes to memory will either write a newly calculated value, or will write the original value. When expressed symbolically, the expression is something like (writeMemory ADDRESS (ite CONDITION VALUE (readMemory ADDRESS))). In this case, the readMemory is part of a read-then-write sequence that has no effect, and this no-op read property can be set in order to express this intent to any analysis that might be triggered by memory reads.

		BaseSemantics::SValuePtr &	carry_out
	)

overridevirtual

Add two values of equal size and a carry bit.

Carry information is returned via carry_out argument. The carry_out value is the tick marks that are written above the first addend when doing long arithmetic like a 2nd grader would do (of course, they'd probably be adding two base-10 numbers). For instance, when adding 00110110 and 11100100:

 '''..'..         <-- carry tick marks: '=carry .=no carry
  00110110
+ 11100100
----------
 100011010

The carry_out value is 11100100.

The width of a and b must be equal; c must have a width of one bit; the return value and carry_out will be the same width as a and b. The carry_out value is allocated herein.

◆ interrupt()

virtual void Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::interrupt	(	int	majorNumber,
		int	minorNumber
	)

overridevirtual

Unconditionally raise an interrupt.

The major and minor numbers are architecture specific. For instance, an x86 INT instruction uses major number zero and the minor number is the interrupt number (e.g., 0x80 for Linux system calls), while an x86 SYSENTER instruction uses major number one.

The base implementation does one of two things. If the current state has an interrupt sub-state then the specified interrupt is raised in that state by setting that interrupt to true. Otherwise, the base implementation does nothing.

overridevirtual

Construct an integer value from a floating-point value.

◆ readRegister()

virtual BaseSemantics::SValuePtr Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::readRegister	(	RegisterDescriptor	reg,
		const BaseSemantics::SValuePtr &	dflt
	)

overridevirtual

Reads a value from a register.

The base implementation simply delegates to the current semantic State, which probably delegates to a register state, but subclasses are welcome to override this behavior at any level.

A register state will typically implement storage for hardware registers, but higher layers (the State, RiscOperators, Dispatcher, ...) should not be concerned about the size of the register they're trying to read. For example, a register state for a 32-bit x86 architecture will likely have a storage location for the 32-bit EAX register, but it should be possible to ask readRegister to return the value of AX (the low-order 16-bits). In order to accomplish this, some level of the readRegister delegations needs to invoke extract to obtain the low 16 bits. The RiscOperators object is passed along the delegation path for this purpose. The inverse concat operation will be needed at some level when we ask readRegister to return a value that comes from multiple storage locations in the register state (such as can happen if an x86 register state holds individual status flags and we ask for the 32-bit EFLAGS register).

If the register state can distinguish between a register that has never been accessed and a register that has only been read, then the dflt value is stored into the register the first time it's read. This ensures that reading the register a second time with no intervening write will return the same value as the first read. If a dflt is not provided then one is constructed by invoking undefined_.

There needs to be a certain level of cooperation between the RiscOperators, State, and register state classes to decide which layer should invoke the extract or concat (or whatever other RISC operations might be necessary).

◆ peekRegister()

virtual BaseSemantics::SValuePtr Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::peekRegister	(	RegisterDescriptor	,
		const BaseSemantics::SValuePtr &	dflt
	)

overridevirtual

Obtain a register value without side effects.

This is a lower-level operation than readRegister in that it doesn't cause the register to be marked as having been read. It is typically used in situations where the register is being accessed for analysis purposes rather than as part of an instruction emulation.

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

◆ writeRegister()

virtual void Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::writeRegister	(	RegisterDescriptor	reg,
		const BaseSemantics::SValuePtr &	a
	)

overridevirtual

Writes a value to a register.

The base implementation simply delegates to the current semantic State, which probably delegates to a register state, but subclasses are welcome to override this behavior at any level.

As with readRegister, writeRegister may need to perform various RISC operations in order to accomplish the task of writing a value to the specified register when the underlying register state doesn't actually store a value for that specific register. The RiscOperations object is passed along for that purpose. See readRegister for more details.

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

◆ readMemory()

virtual BaseSemantics::SValuePtr Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::readMemory	(	RegisterDescriptor	segreg,
		const BaseSemantics::SValuePtr &	addr,
		const BaseSemantics::SValuePtr &	dflt,
		const BaseSemantics::SValuePtr &	cond
	)

overridevirtual

Reads a value from memory.

The implementation (in subclasses) will typically delegate much of the work to the current state's readMemory method.

A MemoryState will implement storage for memory locations and might impose certain restrictions, such as "all memory values must be eight bits". However, the readMemory should not have these constraints so that it can be called from a variety of Dispatcher subclass (e.g., the DispatcherX86 class assumes that readMemory is capable of reading 32-bit values from little-endian memory). The designers of the MemoryState, State, and RiscOperators should collaborate to decide which layer (RiscOperators, State, or MemoryState) is reponsible for combining individual memory locations into larger values. A RiscOperators object is passed along the chain of delegations for this purpose. The RiscOperators might also contain other data that's important during the process, such as an SMT solver.

The segreg argument is an optional segment register. Most architectures have a flat virtual address space and will pass a default-constructed register descriptor whose is_valid() method returns false.

The cond argument is a Boolean value that indicates whether this is a true read operation. If cond can be proven to be false then the read is a no-op and returns an arbitrary value.

The dflt argument determines the size of the value to be read. This argument is also passed along to the lower layers so that they can, if they desire, use it to initialize memory that has never been read or written before.

Implements Rose::BinaryAnalysis::InstructionSemantics::BaseSemantics::RiscOperators.

◆ peekMemory()

virtual BaseSemantics::SValuePtr Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::peekMemory	(	RegisterDescriptor	segreg,
		const BaseSemantics::SValuePtr &	addr,
		const BaseSemantics::SValuePtr &	dflt
	)

overridevirtual

Read memory without side effects.

This is a lower-level operation than readMemory in that it doesn't cause any side effects in the memory state. In all other respects, it's similar to readMemory.

Implements Rose::BinaryAnalysis::InstructionSemantics::BaseSemantics::RiscOperators.

◆ writeMemory()

virtual void Rose::BinaryAnalysis::InstructionSemantics::TraceSemantics::RiscOperators::writeMemory	(	RegisterDescriptor	segreg,
		const BaseSemantics::SValuePtr &	addr,
		const BaseSemantics::SValuePtr &	data,
		const BaseSemantics::SValuePtr &	cond
	)

overridevirtual

Writes a value to memory.

The implementation (in subclasses) will typically delegate much of the work to the current state's writeMemory method.

The segreg argument is an optional segment register. Most architectures have a flat virtual address space and will pass a default-constructed register descriptor whose is_valid() method returns false.

The cond argument is a Boolean value that indicates whether this is a true write operation. If cond can be proved to be false then writeMemory is a no-op.
