There is some attempt to make this function usable for many architectures,

both USE_REL and USE_RELA ['twould be nice if such a critter existed],
|
||
if only to serve as a learning tool.
|
||
|
||
The RELOCATE_SECTION function is called by the new ELF backend linker
|
||
to handle the relocations for a section.
|
||
|
||
The relocs are always passed as Rela structures; if the section
|
||
actually uses Rel structures, the r_addend field will always be
|
||
zero.
|
||
|
||
This function is responsible for adjusting the section contents as
|
||
necessary, and (if using Rela relocs and generating a relocatable
|
||
output file) adjusting the reloc addend as necessary.
|
||
|
||
This function does not have to worry about setting the reloc
|
||
address or the reloc symbol index.
|
||
|
||
LOCAL_SYMS is a pointer to the swapped in local symbols.
|
||
|
||
LOCAL_SECTIONS is an array giving the section in the input file
|
||
corresponding to the st_shndx field of each local symbol.
|
||
|
||
The global hash table entry for the global symbols can be found
|
||
via elf_sym_hashes (input_bfd).
|
||
|
||
When generating relocatable output, this function must handle
|
||
STB_LOCAL/STT_SECTION symbols specially. The output symbol is
|
||
going to be the section symbol corresponding to the output
|
||
section, which means that the addend must be adjusted
|
||
accordingly. */
