ghidra.app.util.bin.format.elf.ElfDefaultGotPltMarkup

public class ElfDefaultGotPltMarkup
extends Object

ElfDefaultGotPltMarkup provides the legacy/default implementation of ELF GOT/PLT processing which handles a limited set of cases. It is intended that over time this default implementation be eliminated although it may form the basis of an abstract implementation for specific processor extensions.

ElfDefaultGotPltMarkup

public ElfDefaultGotPltMarkup(ElfLoadHelper elfLoadHelper)

Method Details

process

public void process(TaskMonitor monitor)
             throws CancelledException

Throws:

CancelledException

processLinkageTable

public void processLinkageTable(String pltName,
 Address minAddress,
 Address maxAddress,
 TaskMonitor monitor)
                         throws CancelledException

Perform disassembly and markup of specified external linkage table which consists of thunks to external functions. If symbols are defined within the linkage table, these will be transitioned to external functions.

Parameters:

pltName - name of PLT section for log messages

minAddress - minimum address of linkage table

maxAddress - maximum address of linkage table

monitor - task monitor

Throws:

CancelledException - task cancelled

setConstant

public static void setConstant(Data data)

Set specified data as constant if contained within a writable block. It can be helpful to the decompiler results if constant pointers are marked as such (e.g., GOT entries)

Parameters:

data - program data

isValidPointer

public static boolean isValidPointer(Data pointerData)

Determine if pointerData refers to a valid memory address or symbol

Parameters:

pointerData - pointer data

Returns:

true if pointer data refers to valid memory address or symbol
