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
|
2003-06-25 08:40:27 +02:00
|
|
|
necessary, and (if using Rela relocs and generating a relocatable
|
2001-04-24 17:08:16 +02:00
|
|
|
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).
|
|
|
|
|
2003-06-25 08:40:27 +02:00
|
|
|
When generating relocatable output, this function must handle
|
2001-04-24 17:08:16 +02:00
|
|
|
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. */
