1125 info 10 ## SP not offset, return PC in LR

1132 This code sequence lets the code at at the start of the PLT determine
1133 which PLT entry was executed by examining 'r29'.
1135 Note that MY_PLT_INDEX skips over the header entries, so the first
1136 actual jump table entry has index zero.
1138 If the offset fits in 16 bits,
1143 addli r28, r26, <_GLOBAL_OFFSET_TABLE_ - 1b + MY_GOT_OFFSET>
1144 moveli r27, <_GLOBAL_OFFSET_TABLE_ - 1b>
1147 shl16insli r29, zero, MY_PLT_INDEX
1154 info 10 ## SP not offset, return PC in LR
1156 For the purpose of backtracing, the procedure linkage table ends with the
1157 following tail entry:
1159 info 10 ## SP not offset, return PC in LR
1161 The 32-bit versions are similar, with ld4s replacing ld, and offsets into
1162 the GOT being multiples of 4 instead of 8.

3082 The RELOCATE_SECTION function is called by the new ELF backend linker
3083 to handle the relocations for a section.
3085 The relocs are always passed as Rela structures.
3087 This function is responsible for adjusting the section contents as
3088 necessary, and (if generating a relocatable output file) adjusting
3089 the reloc addend as necessary.
3091 This function does not have to worry about setting the reloc
3092 address or the reloc symbol index.
3094 LOCAL_SYMS is a pointer to the swapped in local symbols.
3096 LOCAL_SECTIONS is an array giving the section in the input file
3097 corresponding to the st_shndx field of each local symbol.
3099 The global hash table entry for the global symbols can be found
3100 via elf_sym_hashes (input_bfd).
3102 When generating relocatable output, this function must handle
3103 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
3104 going to be the section symbol corresponding to the output
