Typedef Documentation

typedef Sawyer::Container::Set<rose_addr_t> Rose::BinaryAnalysis::Variables::AddressSet

Set of addresses.

Definition at line 30 of file Variables.h.

typedef std::map<int64_t , AddressSet> Rose::BinaryAnalysis::Variables::OffsetToAddresses

Mapping from stack offsets to address sets.

Definition at line 33 of file Variables.h.

typedef std::map<rose_addr_t , AddressSet > Rose::BinaryAnalysis::Variables::AddressToAddresses

Mapping from addresses to address sets.

Definition at line 36 of file Variables.h.

typedef Sawyer::Container::Interval<int64_t> Rose::BinaryAnalysis::Variables::OffsetInterval

Interval of signed offsets.

Definition at line 39 of file Variables.h.

using Rose::BinaryAnalysis::Variables::StackVariables = typedef Sawyer::Container::IntervalMap<OffsetInterval, StackVariable>

Collection of local variables organized by frame offsets.

Definition at line 267 of file Variables.h.

typedef Sawyer::Container::IntervalMap<AddressInterval, GlobalVariable> Rose::BinaryAnalysis::Variables::GlobalVariables

Maps virtual addresses to global variables.

The global variable will be represented in the map at all addresses that the global variable could occupy. E.g., if global variable "g1" starts at 0x4000 and can be up to 1k 4-byte integers, then a record will exist in the map at all addresses from 0x4000 (inclusive) to 0x4100 (exclusive).

Definition at line 352 of file Variables.h.

using Rose::BinaryAnalysis::Variables::VariableFinderPtr = typedef Sawyer::SharedPointer<class VariableFinder>

Shared ownership pointer for VariableFinder.

Definition at line 406 of file Variables.h.

Function Documentation

void Rose::BinaryAnalysis::Variables::initDiagnostics

(

)

Initialize diagnostic output.

This is called automatically when ROSE is initialized.

std::string Rose::BinaryAnalysis::Variables::offsetStr

(

int64_t

offset

)

Format a stack offset as a string.

std::string Rose::BinaryAnalysis::Variables::sizeStr

(

uint64_t

size

)

Format size as a string.

void Rose::BinaryAnalysis::Variables::print	(	const StackVariables &	,
		const Partitioner2::Partitioner &	,
		std::ostream &	out,
		const std::string &	prefix = ""
	)

Print info about multiple local variables.

This output includes such things as the function to which they belong and the defining instructions. The output is multi-line, intended for debugging.

void Rose::BinaryAnalysis::Variables::print	(	const GlobalVariables &	,
		const Partitioner2::Partitioner &	,
		std::ostream &	out,
		const std::string &	prefix = ""
	)

Print info about multiple global variables.

This output includes such things as their addresses, sizes, and the defining instructions. The output is multi-line, intended for debugging.
