Detailed Description

A section + offset based address class.

The Address class allows addresses to be relative to a section that can move during runtime due to images (executables, shared libraries, bundles, frameworks) being loaded at different addresses than the addresses found in the object file that represents them on disk. There are currently two types of addresses for a section:

File addresses represent the virtual addresses that are in the "on disk" object files. These virtual addresses are converted to be relative to unique sections scoped to the object file so that when/if the addresses slide when the images are loaded/unloaded in memory, we can easily track these changes without having to update every object (compile unit ranges, line tables, function address ranges, lexical block and inlined subroutine address ranges, global and static variables) each time an image is loaded or unloaded.

Load addresses represent the virtual addresses where each section ends up getting loaded at runtime. Before executing a program, it is common for all of the load addresses to be unresolved. When a DynamicLoader plug-in receives notification that shared libraries have been loaded/unloaded, the load addresses of the main executable and any images (shared libraries) will be resolved/unresolved. When this happens, breakpoints that are in one of these sections can be set/cleared.

Member Enumeration Documentation

◆ DumpStyle

Dump styles allow the Address::Dump(Stream *,DumpStyle) const function to display Address contents in a variety of ways.

Enumerator
DumpStyleInvalid 

Invalid dump style.

DumpStyleSectionNameOffset 

Display as the section name + offset.

// address for printf in libSystem.B.dylib as a section name + offset
libSystem.B.dylib.__TEXT.__text + 0x0005cfdf
DumpStyleSectionPointerOffset 

Display as the section pointer + offset (debug output).

// address for printf in libSystem.B.dylib as a section pointer +
offset (lldb::Section *)0x35cc50 + 0x000000000005cfdf

DumpStyleResolvedDescription 

Display the details about what an address resolves to.

This can be anything from a symbol context summary (module, function/symbol, and file and line), to information about what the pointer points to if the address is in a section (section of pointers, c strings, etc).

DumpStyleResolvedDescriptionNoModule 
DumpStyleResolvedDescriptionNoFunctionArguments 
DumpStyleNoFunctionName 

Elide the function name; display an offset into the current function.

Used primarily in disassembly symbolication

DumpStyleDetailedSymbolContext 

Detailed symbol context information for an address for all symbol context members.

DumpStyleResolvedPointerDescription 

Dereference a pointer at the current address and then lookup the dereferenced address using DumpStyleResolvedDescription.

◆ GetAddressClass()

AddressClass Address::GetAddressClass ( ) const

◆ GetCallableLoadAddress()

addr_t Address::GetCallableLoadAddress ( Target target,
bool  is_indirect = false 
) const

Get the load address as a callable code load address.

This function will first resolve its address to a load address. Then, if the address turns out to be in code address, return the load address that would be required to call or return to. The address might have extra bits set (bit zero will be set to Thumb functions for an ARM target) that are required when changing the program counter to setting a return address.

Returns
The valid load virtual address, or LLDB_INVALID_ADDRESS if the address is currently not loaded.

◆ GetFileAddress()

addr_t Address::GetFileAddress ( ) const

Get the file address.

If an address comes from a file on disk that has section relative addresses, then it has a virtual address that is relative to unique section in the object file.

Returns
The valid file virtual address, or LLDB_INVALID_ADDRESS if the address doesn't have a file virtual address (image is from memory only with no representation on disk).

Get the load address.

If an address comes from a file on disk that has section relative addresses, then it has a virtual address that is relative to unique section in the object file. Sections get resolved at runtime by DynamicLoader plug-ins as images (executables and shared libraries) get loaded/unloaded. If a section is loaded, then the load address can be resolved.

Returns

◆ GetOpcodeLoadAddress()

addr_t Address::GetOpcodeLoadAddress ( Target target,
AddressClass  addr_class = AddressClass::eInvalid 
) const

Get the load address as an opcode load address.

This function will first resolve its address to a load address. Then, if the address turns out to be in code address, return the load address for an opcode. This address object might have extra bits set (bit zero will be set to Thumb functions for an ARM target) that are required for changing the program counter and this function will remove any bits that are intended for these special purposes. The result of this function can be used to safely write a software breakpoint trap to memory.

Returns
The valid load virtual address with extra callable bits removed, or LLDB_INVALID_ADDRESS if the address is currently not loaded.

◆ IsSectionOffset()

bool lldb_private::Address::IsSectionOffset ( ) const
inline

Check if an address is section offset.

When converting a virtual file or load address into a section offset based address, we often need to know if, given a section list, if the address was able to be converted to section offset. This function returns true if the current value contained in this object is section offset based.

Returns
Returns true if the address has a valid section and offset, false otherwise.

◆ IsValid()

bool lldb_private::Address::IsValid ( ) const
inline

Check if the object state is valid.

A valid Address object contains either a section pointer and offset (for section offset based addresses), or just a valid offset (for absolute addresses that have no section).

Returns
Returns true if the offset is valid, false otherwise.

◆ SetLoadAddress()

bool Address::SetLoadAddress ( lldb::addr_t  load_addr,
Target target,
bool  allow_section_end = false 
)

Set the address to represent load_addr.

The address will attempt to find a loaded section within target that contains load_addr. If successful, this address object will have a valid section and offset. Else this address object will have no section (NULL) and the offset will be load_addr.

Parameters
[in]load_addrA load address from a current process.
[in]targetThe target to use when trying resolve the address into a section + offset. The Target's SectionLoadList object is used to resolve the address.
[in]allow_section_endIf true, treat an address pointing to the end of the module as belonging to that module.
Returns
Returns true if the load address was resolved to be section/offset, false otherwise. It is often ok for an address to not resolve to a section in a module, this often happens for JIT'ed code, or any load addresses on the stack or heap.
