Detailed Description

Parent class of classes representing accesses to memory.

Member Enumeration Documentation

enum otawa::AccessedAddress::kind_t

Describe the different implementation of an accessed address.

Enumerator
ANY	Represents the most imprecise memory access: it may potentially concern the full memory address space.
SP	Represents an stack pointer relative address with a constant offset. Instances of this kind can be casted into SPAddress.
ABS	Represents an address defined by its absolute and constant value. Instances of this kind can be casted into AbsAddress.

Constructor & Destructor Documentation

otawa::AccessedAddress::AccessedAddress ( Inst *  instruction, bool  is_store, kind_t  kind = ANY  )

Member Function Documentation

Inst * otawa::AccessedAddress::instruction ( void  ) const

inline

Get the instruction where this memory access applies.

Returns

Instruction accessing the memory.

References inst.

bool otawa::AccessedAddress::isLoad ( void  ) const

inline

Test if a store is performed on the accessed address.

Returns

True if it is a store.

References store.

bool otawa::AccessedAddress::isStore ( void  ) const

inline

Test if a store is performed on the accessed address.

Returns

True if it is a store.
