◆ CalculateStrata()

ObjectFile::Strata ObjectFileELF::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 3266 of file ObjectFileELF.cpp.

◆ CalculateType()

ObjectFile::Type ObjectFileELF::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.

void ObjectFileELF::Dump ( lldb_private::Stream s)

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]sThe stream to which to dump the object description.

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

◆ GetBaseAddress()

Address ObjectFileELF::GetBaseAddress ( )
overridevirtual

Returns base address of this object file.

This also sometimes referred to as the "preferred load address" or the "image base address". Addresses within object files are often expressed relative to this base. If this address corresponds to a specific section (usually the first byte of the first section) then the returned address will have this section set. Otherwise, the address will just have the offset member filled in, indicating that this represents a file address.

◆ GetImageInfoAddress()

Address ObjectFileELF::GetImageInfoAddress ( lldb_private::Target target)
overridevirtual

Similar to Process::GetImageInfoAddress().

Some platforms embed auxiliary structures useful to debuggers in the address space of the inferior process.

ELF, for example, provides a means to hook into the runtime linker so that a debugger may monitor the loading and unloading of shared libraries.
