1044 
 
1045 
   The RELOCATE_SECTION function is called by the new ELF backend linker
1046 
   to handle the relocations for a section.
1047 
 
1048 
   The relocs are always passed as Rela structures; if the section
1049 
   actually uses Rel structures, the r_addend field will always be
1050 
   zero.
1051 
 
1052 
   This function is responsible for adjusting the section contents as
1053 
   necessary, and (if using Rela relocs and generating a relocatable
1054 
   output file) adjusting the reloc addend as necessary.
1055 
 
1056 
   This function does not have to worry about setting the reloc
1057 
   address or the reloc symbol index.
1058 
 
1059 
   LOCAL_SYMS is a pointer to the swapped in local symbols.
1060 
 
1061 
   LOCAL_SECTIONS is an array giving the section in the input file
1062 
   corresponding to the st_shndx field of each local symbol.
1063 
 
1064 
   The global hash table entry for the global symbols can be found
1065 
   via elf_sym_hashes (input_bfd).
1066 
 
1067 
   When generating relocatable output, this function must handle
1068 
   STB_LOCAL/STT_SECTION symbols specially.  The output symbol is
1069 
   going to be the section symbol corresponding to the output
1070 
   section, which means that the addend must be adjusted
1071 
   accordingly.  */
