/* This code is taken from elf32-m32r.c
|
|
|
|
|
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 adjust 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. */
