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.

1143 addli r28, r26, <_GLOBAL_OFFSET_TABLE_ - 1b + MY_GOT_OFFSET>

1161 The 32-bit versions are similar, with ld4s replacing ld, and offsets into

3089 The RELOCATE_SECTION function is called by the new ELF backend linker

3094 This function is responsible for adjusting the section contents as
3095 necessary, and (if generating a relocatable output file) adjusting
3096 the reloc addend as necessary.
3098 This function does not have to worry about setting the reloc

3101 LOCAL_SYMS is a pointer to the swapped in local symbols.
3103 LOCAL_SECTIONS is an array giving the section in the input file
3104 corresponding to the st_shndx field of each local symbol.
3106 The global hash table entry for the global symbols can be found
3107 via elf_sym_hashes (input_bfd).

3110 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
