Detailed Description

A resolver for segmented architectures.

When the decompiler is attempting to resolve embedded constants as pointers, this class tries to recover segment info for near pointers by looking up tracked registers in context

Constructor & Destructor Documentation

SegmentedResolver()

SegmentedResolver::SegmentedResolver ( Architecture *  g, AddrSpace *  sp, SegmentOp *  sop  )

inline

Construct a segmented resolver

Parameters

g	is the owning Architecture
sp	is the segmented space
sop	is the segment operator

resolve()

Address SegmentedResolver::resolve ( uintb  val, int4  sz, const Address &  point  )

virtual

Virtual destructor

The main resolver method.

Given a native constant in a specific context, resolve what address is being referred to.

Parameters

val	is constant to be resolved to an address
sz	is the size of val in context.
point	is the address at which this constant is being used

Returns

the resolved Address

Implements AddressResolver.
