Member Function Documentation

void AddrSpaceManager::addSpacebasePointer	(	SpacebaseSpace *	basespace,
		const VarnodeData &	ptrdata,
		int4	truncSize,
		bool	stackGrowth
	)

protected

Set the base register of a spacebase space.

Perform the privileged act of associating a base register with an existing virtual space

Parameters

basespace	is the virtual space
ptrdata	is the location data for the base register
truncSize	is the size of the space covered by the base register
stackGrowth	is true if the stack grows "normally" towards address 0

References SpacebaseSpace::setBaseRegister().

void AddrSpaceManager::assignShortcut ( AddrSpace * spc )

protected

Select a shortcut character for a new space.

Assign a shortcut character to the given address space. This routine makes use of the desired type of the new space and info about shortcuts for spaces that already exist to pick a unique and consistent character. This method also builds up a map from short to AddrSpace object.

Parameters

spc	is the given AddrSpace

References AddrSpace::getName(), AddrSpace::getType(), IPTR_CONSTANT, IPTR_FSPEC, IPTR_INTERNAL, IPTR_IOP, IPTR_JOIN, IPTR_PROCESSOR, IPTR_SPACEBASE, and AddrSpace::shortcut.

Address AddrSpaceManager::constructFloatExtensionAddress	(	const Address &	realaddr,
		int4	realsize,
		int4	logicalsize
	)

Build a logically lower precision storage location for a bigger floating point register.

This handles the situation where we need to find a logical address to hold the lower precision floating-point value that is stored in a bigger register If the logicalsize (precision) requested matches the -realsize- of the register just return the real address. Otherwise construct a join address to hold the logical value

Parameters

realaddr	is the address of the real floating-point register
realsize	is the size of the real floating-point register
logicalsize	is the size (lower precision) size of the logical value

References VarnodeData::getAddr(), Address::getOffset(), Address::getSpace(), and JoinRecord::getUnified().

Address AddrSpaceManager::constructJoinAddress	(	const Translate *	translate,
		const Address &	hiaddr,
		int4	hisz,
		const Address &	loaddr,
		int4	losz
	)

Build a logical whole from register pairs.

This handles the common case, of trying to find a join address given a high location and a low location. This may not return an address in the join address space. It checks for the case where the two pieces are contiguous locations in a mappable space, in which case it just returns the containing address

Parameters

translate	is the Translate object used to find registers
hiaddr	is the address of the most significant piece to be joined
hisz	is the size of the most significant piece
loaddr	is the address of the least significant piece
losz	is the size of the least significant piece

Returns: an address representing the start of the joined range

void AddrSpaceManager::renormalizeJoinAddress	(	Address &	addr,
		int4	size
	)

Make sure a possibly offset join address has a proper JoinRecord.

If an Address in the join AddressSpace is shifted from its original offset, it may no longer have a valid JoinRecord. The shift or size change may even make the address of one of the pieces a more natural representation. Given a new Address and size, this method decides if there is a matching JoinRecord. If not it either constructs a new JoinRecord or computes the address within the containing piece. The given Address is changed if necessary either to the offset corresponding to the new JoinRecord or to a normal non-join Address.

Parameters

addr	is the given Address
size	is the size of the range in bytes

References JoinRecord::getEquivalentAddress(), Address::getOffset(), Address::isInvalid(), VarnodeData::offset, JoinRecord::pieces, VarnodeData::size, VarnodeData::space, and JoinRecord::unified.

Address AddrSpaceManager::resolveConstant	(	AddrSpace *	spc,
		uintb	val,
		int4	sz,
		const Address &	point,
		uintb &	fullEncoding
	)		const

Resolve a native constant into an Address.

If there is a special resolver for the AddrSpace, this is invoked, otherwise basic wordsize conversion and wrapping is performed. If the address encoding is partial (as in a near pointer) and the full encoding can be recovered, it is passed back. The sz parameter indicates the number of bytes in constant and is used to determine if the constant is a partial or full pointer encoding. A value of -1 indicates the value is known to be a full encoding.

Parameters

spc	is the space to generate the address from
val	is the constant encoding of the address
sz	is the size of the constant encoding (or -1)
point	is the context address (for recovering full encoding info if necessary)
fullEncoding	is used to pass back the recovered full encoding of the pointer

Returns: the formal Address associated with the encoding

AddrSpace * AddrSpaceManager::restoreXmlSpace	(	const Element *	el,
		const Translate *	trans
	)

protected

Add a space to the model based an on XML tag.

The initialization of address spaces is the same across all variants of the Translate object. This routine initializes a single address space from a parsed XML tag. It knows which class derived from AddrSpace to instantiate based on the tag name.

Parameters

el	is the parsed XML tag
trans	is the translator object to be associated with the new space

Returns: a pointer to the initialized AddrSpace

References AddrSpace::AddrSpace(), Element::getName(), IPTR_PROCESSOR, AddrSpace::restoreXml(), and SpacebaseSpace::SpacebaseSpace().

void AddrSpaceManager::restoreXmlSpaces	(	const Element *	el,
		const Translate *	trans
	)

protected

Restore address spaces in the model from an XML tag.

This routine initializes (almost) all the address spaces used for a particular processor by using a <spaces> tag, which contains subtags for the specific address spaces. This also instantiates the builtin constant space. It should probably also instantiate the iop, fspec, and join spaces, but this is currently done by the Architecture class.

Parameters

el	is the parsed <spaces> tag
trans	is the processor translator to be associated with the spaces

void AddrSpaceManager::setDeadcodeDelay	(	AddrSpace *	spc,
		int4	delaydelta
	)

Set the deadcodedelay for a specific space.

Set the number of passes for a specific AddrSpace before deadcode removal is allowed for that space.

Parameters

spc	is the AddrSpace to change
delaydelta	is the number of rounds to the delay should be set to

References AddrSpace::deadcodedelay.

void AddrSpaceManager::setDefaultCodeSpace ( int4 index )

protected

Set the default address space (for code)

Once all the address spaces have been initialized, this routine should be called once to establish the official default space for the processor, via its index. Should only be called during initialization.

Parameters

index is the index of the desired default space

References AddrSpace::index.

void AddrSpaceManager::setDefaultDataSpace ( int4 index )

protected

Set the default address space for data.

If the architecture has different code and data spaces, this routine can be called to set the data space after the code space has been set.

Parameters

index is the index of the desired default space

References AddrSpace::index.

void AddrSpaceManager::setInferPtrBounds ( const Range & range )

protected

Set the range of addresses that can be inferred as pointers.

This method establishes for a single address space, what range of constants are checked as possible symbol starts, when it is not known apriori that a constant is a pointer.

Parameters

range is the range of values for a single address space

References Range::getFirst(), Range::getLast(), Range::getSpace(), AddrSpace::pointerLowerBound, and AddrSpace::pointerUpperBound.

void AddrSpaceManager::setReverseJustified ( AddrSpace * spc )

protected

Set reverse justified property on this space.

For spaces with alignment restrictions, the address of a small variable must be justified within a larger aligned memory word, usually either to the left boundary for little endian encoding or to the right boundary for big endian encoding. Some compilers justify small variables to the opposite side of the one indicated by the endianness. Setting this property on a space causes the decompiler to use this justification

References AddrSpace::reverse_justification, and AddrSpace::setFlags().

void AddrSpaceManager::truncateSpace ( const TruncationTag & tag )

Mark a space as truncated from its original size.

Mark the named space as truncated from its original size

Parameters

tag	is a description of the space and how it should be truncated
