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