1024
1025 This is boiler-plate code copied from fr30.
1026
1027 The RELOCATE_SECTION function is called by the new ELF backend linker
1028 to handle the relocations for a section.
1029
1030 The relocs are always passed as Rela structures; if the section
1031 actually uses Rel structures, the r_addend field will always be
1032 zero.
1033
1034 This function is responsible for adjusting the section contents as
1035 necessary, and (if using Rela relocs and generating a relocatable
1036 output file) adjusting the reloc addend as necessary.
1037
1038 This function does not have to worry about setting the reloc
1039 address or the reloc symbol index.
1040
1041 LOCAL_SYMS is a pointer to the swapped in local symbols.
1042
1043 LOCAL_SECTIONS is an array giving the section in the input file
1044 corresponding to the st_shndx field of each local symbol.
1045
1046 The global hash table entry for the global symbols can be found
1047 via elf_sym_hashes (input_bfd).
1048
1049 When generating relocatable output, this function must handle
1050 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
1051 going to be the section symbol corresponding to the output
1052 section, which means that the addend must be adjusted
1053 accordingly. */
