◆ CalculateStrata()

ObjectFile::Strata ObjectFileXCOFF::CalculateStrata ( )

overridevirtual

The object file should be able to calculate the strata of the object file.

Many object files for platforms might be for either user space debugging or for kernel debugging. If your object file subclass can figure this out, it will help with debugger plug-in selection when it comes time to debug.

Returns: The calculated object file strata for the current object file.

Implements lldb_private::ObjectFile.

Definition at line 215 of file ObjectFileXCOFF.cpp.

References lldb_private::ObjectFile::eStrataUnknown.

◆ CalculateType()

ObjectFile::Type ObjectFileXCOFF::CalculateType ( )

overridevirtual

The object file should be able to calculate its type by looking at its file header and possibly the sections or other data in the object file.

The file type is used in the debugger to help select the correct plug- ins for the job at hand, so this is important to get right. If any eTypeXXX definitions do not match up with the type of file you are loading, please feel free to add a new enumeration value.

Returns: The calculated file type for the current object file.

◆ Dump()

void ObjectFileXCOFF::Dump ( lldb_private::Stream * s )

overridevirtual

Dump a description of this object to a Stream.

Dump a description of the current contents of this object to the supplied stream s. The dumping should include the section list if it has been parsed, and the symbol table if it has been parsed.

Parameters

[in] s The stream to which to dump the object description.

Implements lldb_private::ObjectFile.

Definition at line 195 of file ObjectFileXCOFF.cpp.

◆ GetAddressByteSize()

uint32_t ObjectFileXCOFF::GetAddressByteSize ( ) const

overridevirtual

Gets the address size in bytes for the current object file.

Returns: The size of an address in bytes for the currently selected architecture (and object for archives). Returns zero if no architecture or object has been selected.

Implements lldb_private::ObjectFile.

Definition at line 180 of file ObjectFileXCOFF.cpp.

◆ GetAddressClass()

AddressClass ObjectFileXCOFF::GetAddressClass ( lldb::addr_t file_addr )

overridevirtual

Get the address type given a file address in an object file.

Many binary file formats know what kinds This is primarily for ARM binaries, though it can be applied to any executable file format that supports different opcode types within the same binary. ARM binaries support having both ARM and Thumb within the same executable container. We need to be able to get

Returns: The size of an address in bytes for the currently selected architecture (and object for archives). Returns zero if no architecture or object has been selected.

References lldb::eByteOrderBig.

◆ GetDependentModules()

uint32_t ObjectFileXCOFF::GetDependentModules ( lldb_private::FileSpecList & file_list )

overridevirtual

Extract the dependent modules from an object file.

If an object file has information about which other images it depends on (such as shared libraries), this function will provide the list. Since many executables or shared libraries may depend on the same files, FileSpecList::AppendIfUnique(const FileSpec &) should be used to make sure any files that are added are not already in the list.

Parameters

[out] file_list A list of file specification objects that gets dependent files appended to.

Returns: The number of new files that were appended to file_list.

◆ GetUUID()

UUID ObjectFileXCOFF::GetUUID ( )

overridevirtual

Gets the UUID for this object file.

If the object file format contains a UUID, the value should be returned. Else ObjectFile instances should return the MD5 checksum of all of the bytes for the object file (or memory for memory based object files).

Returns: The object file's UUID. In case of an error, an empty UUID is returned.

◆ ParseHeader()

bool ObjectFileXCOFF::ParseHeader ( )

overridevirtual

Attempts to parse the object header.

This function is used as a test to see if a given plug-in instance can parse the header data already contained in ObjectFile::m_data. If an object file parser does not recognize that magic bytes in a header, false should be returned and the next plug-in can attempt to parse an object file.

Returns: Returns true if the header was parsed successfully, false otherwise.

overridevirtual

Parse the symbol table into the provides symbol table object.

Symbol table parsing will be done once when this function is called by each object file plugin. All of the necessary locks will already be acquired before this function is called and the symbol table object to populate is supplied as an argument and doesn't need to be created by each plug-in.

Parameters

The	symbol table to populate.
