struct InitFiniInfo

Defined at line 36 of file ../../src/lib/elfldltl/include/lib/elfldltl/init-fini.h

This represents the information about either initializers or finalizers for

one ELF module. Two separate InitFiniInfo objects are used for a module's

initializers and finalizers.

This is normally populated by a call to elfldltl::DecodeDynamic using an

elfldltl::DynamicInitObserver or elfldltl::DynamicFiniObserver observer.

The VisitInit or VisitFini methods provide general ordered access to the

function addresses in each list. The correct method should be used for each

kind of list to get the appropriate ordering of elements.

The CallInit and CallFini methods directly call each function in order, for

immediate in-process uses.

void InitFiniInfo<Elf, AbiTraits> (std::span<const Addr> array)

InitFiniInfo can be default-constructed and then set_* called, or it can

be explicitly constructed from an array with no legacy singleton.

std::span<const Addr> array ()

An array of function pointers, in the .init_array or .fini_array section,

which is normally part of the RELRO segment. So the pointers here are

unrelocated in the file, but dynamic relocation records apply simple

fixup. As this points directly into the load image in the Memory object,

if that image is being relocated in place, then these values will be

absolute function pointers after relocation. If the original file data

(or the load image before relocation) is being read, the these addresses

need the load bias added.

std::optional<Addr> legacy ()

A single function pointer, from the legacy DT_INIT or DT_FINI entry. This

is not contiguous with the array and is stored separately in the ELF

headers where no relocation records apply. So this address always needs

the load bias added to yield a runtime function pointer.
