Description

List of virtual address users.

This is a list of users of virtual addresses. A user is either an instruction (and basic block owners) or a data block (and function and basic block owners). The list is maintained in a sorted order according to instruction or data block starting address. The class ensures that all users in the list have valid pointers and that the list contains no duplicates.

Member Function Documentation

Sawyer::Optional<AddressUser> Rose::BinaryAnalysis::Partitioner2::AddressUsers::instructionExists ( rose_addr_t insnStart ) const

Determines if an instruction exists in the list.

If an instruction with the specified starting address exists in the list then the address user information is returned, otherwise nothing is returned.

Sawyer::Optional<OwnedDataBlock> Rose::BinaryAnalysis::Partitioner2::AddressUsers::dataBlockExists ( const DataBlock::Ptr & ) const

Determines if a data block exists in the list.

If the specified data block exists then its ownership information is returned, otherwise nothing is returned.

Sawyer::Optional<OwnedDataBlock> Rose::BinaryAnalysis::Partitioner2::AddressUsers::dataBlockExists ( rose_addr_t dbStart ) const

Determines if a data block exists in the list.

If a data block with the specified starting address exists in the list then its ownership information is returned, otherwise nothing is returned. It is possible that multiple data blocks can exist at a particular address, in which case an arbitrary one is returned.

BasicBlock::Ptr Rose::BinaryAnalysis::Partitioner2::AddressUsers::findBasicBlock ( rose_addr_t bbVa ) const

Find the basic block that starts at this address.

If this user is an instruction, then scan through its basic block owners (usually just one) and return a pointer to any basic block that starts at this address. Basic blocks in the AUM have unique starting addresses, thus this function returns either the pointer to such a block or the null pointer.

void Rose::BinaryAnalysis::Partitioner2::AddressUsers::insertInstruction	(	SgAsmInstruction *	,
		const BasicBlock::Ptr &
	)

Insert an instruction/basic block pair.

Neither the instruction nor the basic block may be null. If this list already contains the specified instruction, then the specified basic block is merged into its owner list.

Referenced by AddressUsers().

void Rose::BinaryAnalysis::Partitioner2::AddressUsers::insertDataBlock ( const OwnedDataBlock & )

Insert a data block.

The specified data block ownership information (which must be valid) is inserted into this list of users. If this list already contains an ownership record for the data block, then the specified record is merged into the existing record.

Referenced by AddressUsers().

void Rose::BinaryAnalysis::Partitioner2::AddressUsers::insert ( const AddressUsers & )

Inser a user.

The specified user information is inserted into this list of users. If this list already contains an equal record then the specified record is not inserted.

Referenced by Rose::BinaryAnalysis::Partitioner2::AddressUsageMap::overlapping().

void Rose::BinaryAnalysis::Partitioner2::AddressUsers::eraseInstruction	(	SgAsmInstruction *	,
		const BasicBlock::Ptr &
	)

Erase an instruction/basic block pair from the list.

Finds the specified instruction in the list and removes the specified basic block owner. If this results in the instruction not being owned by any blocks then the instruction is removed.

void Rose::BinaryAnalysis::Partitioner2::AddressUsers::eraseDataBlock ( const DataBlock::Ptr & )

Erase a data block user.

Erases the specified data block from the list. If the data block is null or the list does not contain the data block then this is a no-op.

static bool Rose::BinaryAnalysis::Partitioner2::AddressUsers::selectAllUsers ( const AddressUser & )

inlinestatic

Selector to select all users.

This selector is the default for methods like AddressUsageMap::overlapping, and causes all users to be selected.

static bool Rose::BinaryAnalysis::Partitioner2::AddressUsers::selectBasicBlocks ( const AddressUser & user )

inlinestatic

Selector to select instructions and basic blocks.

This selector can be passed as the argument to the select method, or to methods like AddressUsageMap::overlapping to select only those users that are instructions and basic blocks.

std::vector<SgAsmInstruction*> Rose::BinaryAnalysis::Partitioner2::AddressUsers::instructions ( ) const

Returns a list of distinct instructions sorted by starting address. The return value is not an AddressUsers because it is more useful to have a list of distinct instructions, and because the instructionUsers method returns the other information already.

std::vector<BasicBlock::Ptr> Rose::BinaryAnalysis::Partitioner2::AddressUsers::instructionOwners ( ) const
