   1 # Relocations against undefined symbols would be incorrectly let through
   2 # by mips_elf_calculate_relocation() once the result of the
   3 # ->undefined_symbol() callback has been interpreted in the opposite
   4 # sense.  The link would fail anyway, but for R_MIPS_GOT_PAGE relocations
   5 # a failure of the following assertion:
   6 #
   7 # BFD_ASSERT (h->dynindx >= global_got_dynindx);
   8 #
   9 # would additionally be reported in mips_elf_global_got_index(), because
  10 # at this point h->dynindx for the undefined symbol would be set to -1.
  11 # Other kinds of GOT relocations allocate a GOT index for the symbol
  12 # referred and set its h->dynindx in _bfd_mips_elf_check_relocs(), but
  13 # R_MIPS_GOT_PAGE relocations only allocate a GOT page at that point and
  14 # for undefined symbols the page never gets resolved any further.
