1110 info 10 ## SP not offset, return PC in LR
1113 shl16insli r29, zero, MY_PLT_INDEX
1117 This code sequence lets the code at at the start of the PLT determine
1118 which PLT entry was executed by examining 'r29'.
1120 Note that MY_PLT_INDEX skips over the header entries, so the first
1121 actual jump table entry has index zero.
1123 If the offset fits in 16 bits,
1128 addli r28, r26, <_GLOBAL_OFFSET_TABLE_ - 1b + MY_GOT_OFFSET>
1129 moveli r27, <_GLOBAL_OFFSET_TABLE_ - 1b>
1132 shl16insli r29, zero, MY_PLT_INDEX
1139 info 10 ## SP not offset, return PC in LR
1141 For the purpose of backtracing, the procedure linkage table ends with the
1142 following tail entry:
1144 info 10 ## SP not offset, return PC in LR
1146 The 32-bit versions are similar, with ld4s replacing ld, and offsets into
1147 the GOT being multiples of 4 instead of 8.

2817 /* Relocate an TILEGX ELF section.
2819 The RELOCATE_SECTION function is called by the new ELF backend linker
2820 to handle the relocations for a section.
2822 The relocs are always passed as Rela structures.
2824 This function is responsible for adjusting the section contents as
2825 necessary, and (if generating a relocatable output file) adjusting
2826 the reloc addend as necessary.
2828 This function does not have to worry about setting the reloc
2829 address or the reloc symbol index.
2831 LOCAL_SYMS is a pointer to the swapped in local symbols.
2833 LOCAL_SECTIONS is an array giving the section in the input file
2834 corresponding to the st_shndx field of each local symbol.
2836 The global hash table entry for the global symbols can be found
2837 via elf_sym_hashes (input_bfd).
2839 When generating relocatable output, this function must handle
2840 STB_LOCAL/STT_SECTION symbols specially. The output symbol is
2841 going to be the section symbol corresponding to the output
2842 section, which means that the addend must be adjusted
