1028 The RELOCATE_SECTION function is called by the new ELF backend linker
1029 to handle the relocations for a section.
1030
1031 The relocs are always passed as Rela structures; if the section
1032 actually uses Rel structures, the r_addend field will always be
1033 zero.
1034
1035 This function is responsible for adjusting the section contents as
1049f94e 1036 necessary, and (if using Rela relocs and generating a relocatable
fdeafce7
JE
1037 output file) adjusting the reloc addend as necessary.
1038
1039 This function does not have to worry about setting the reloc
1040 address or the reloc symbol index.
1041
1042 LOCAL_SYMS is a pointer to the swapped in local symbols.
1043
1044 LOCAL_SECTIONS is an array giving the section in the input file
1045 corresponding to the st_shndx field of each local symbol.
1046
1047 The global hash table entry for the global symbols can be found
1048 via elf_sym_hashes (input_bfd).
1049
1049f94e 1050 When generating relocatable output, this function must handle
fdeafce7
JE
1051 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
1052 going to be the section symbol corresponding to the output
1053 section, which means that the addend must be adjusted
1054 accordingly. */
