Detailed Description

This is the basic interface for storing domains.

The abstract interpreters should use this interface by default.

Member Function Documentation

◆  abstract_state_before() [1/2]

virtual cstate_ptrt ai_storage_baset::abstract_state_before ( locationt  l,
const ai_domain_factory_baset &  fac 
) const
pure virtual

Implemented in location_sensitive_storaget, and history_sensitive_storaget.

◆  abstract_state_before() [2/2]

virtual cstate_ptrt ai_storage_baset::abstract_state_before ( trace_ptrt  p,
const ai_domain_factory_baset &  fac 
) const
pure virtual

Non-modifying access to the stored domains, used in the ai_baset public interface.

In the case of un-analysed locals this should create a domain The history version is the primary version, the location one may simply join all of the histories that reach the given location

Implemented in location_sensitive_storaget, and history_sensitive_storaget.

◆  abstract_traces_before()

virtual ctrace_set_ptrt ai_storage_baset::abstract_traces_before ( locationt  l ) const
pure virtual

Returns all of the histories that have reached the start of the instruction.

Implemented in trace_map_storaget.

◆  clear()

virtual void ai_storage_baset::clear ( )
inlinevirtual

Reset the abstract state.

Reimplemented in trace_map_storaget, location_sensitive_storaget, and history_sensitive_storaget.

Definition at line 80 of file ai_storage.h.

◆  get_state()

virtual statet & ai_storage_baset::get_state ( trace_ptrt  p,
const ai_domain_factory_baset &  fac 
)
pure virtual

Look up the analysis state for a given history, instantiating a new domain if required.

Implemented in location_sensitive_storaget, and history_sensitive_storaget.

◆  prune()

virtual void ai_storage_baset::prune ( locationt  l )
inlinevirtual

Notifies the storage that the user will not need the domain object(s) for this location.

After this has been called abstract_state_before may return an over-approximation of the value and get_state may give an under-approximation (forcing recomputation). If there are multiple histories that reach this location all will be affected
