1128 This code sequence lets the code at at the start of the PLT determine
1129 which PLT entry was executed by examining 'r29'.
1131 Note that MY_PLT_INDEX skips over the header entries, so the first
1132 actual jump table entry has index zero.
1134 If the offset fits in 16 bits,
1139 addli r28, r26, <_GLOBAL_OFFSET_TABLE_ - 1b + MY_GOT_OFFSET>
1140 moveli r27, <_GLOBAL_OFFSET_TABLE_ - 1b>
1143 shl16insli r29, zero, MY_PLT_INDEX
1150 info 10 ## SP not offset, return PC in LR
1152 For the purpose of backtracing, the procedure linkage table ends with the
1153 following tail entry:
1155 info 10 ## SP not offset, return PC in LR
1157 The 32-bit versions are similar, with ld4s replacing ld, and offsets into
1158 the GOT being multiples of 4 instead of 8.

2906 /* Relocate an TILEGX ELF section.
2908 The RELOCATE_SECTION function is called by the new ELF backend linker
2909 to handle the relocations for a section.
2911 The relocs are always passed as Rela structures.
2913 This function is responsible for adjusting the section contents as
2914 necessary, and (if generating a relocatable output file) adjusting
2915 the reloc addend as necessary.
2917 This function does not have to worry about setting the reloc
2918 address or the reloc symbol index.
2920 LOCAL_SYMS is a pointer to the swapped in local symbols.
2922 LOCAL_SECTIONS is an array giving the section in the input file
2923 corresponding to the st_shndx field of each local symbol.
2925 The global hash table entry for the global symbols can be found
2926 via elf_sym_hashes (input_bfd).
2928 When generating relocatable output, this function must handle
2929 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2930 going to be the section symbol corresponding to the output
2931 section, which means that the addend must be adjusted
