|
|
|
|
|
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
|
2003-06-25 14:40:27 +08:00

|
relocatable output file) adjusting the reloc addend as
|
1999-05-03 15:29:11 +08:00
|
|
|
|
necessary.
|

|

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).

1999-05-03 15:29:11 +08:00
|
|
|
|
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. */
