ld-mips-elf/pic-and-nonpic-6-n64.sd: New tests.
* ld-mips-elf/mips-elf.exp: Run them.
* elfxx-mips.c (mips_elf_record_relocs): Defer allocation of a
global GOT entry when deferring allocation of dynamic relocations.
(allocate_dynrelocs): When allocating deferred dynamic relocations,
also do the deferred allocation of a GOT entry.
* elfxx-mips.c (mips_got_info): Add a "reloc_only_gotno" field.
(mips_elf_got_section): Delete.
(mips_elf_sort_hash_table): Use g->reloc_only_gotno to decide
how many reloc-only entries there are.
(mips_elf_count_got_symbols): Adjust g->reloc_only_gotno as
well as g->global_gotno.
(mips_elf_make_got_per_bfd): Initialize reloc_only_gotno.
(mips_elf_multi_got): Likewise. Use gg->reloc_only_gotno
rather than gg->assigned_gotno to store the number of
reloc-only GOT entries.
(mips_elf_create_got_section): Remove the MAYBE_EXCLUDE parameter.
Initialize reloc_only_gotno.
(mips_elf_calculate_relocation): Check htab->got_info instead of
dynobj when deciding whether to call mips_elf_adjust_gp,
(_bfd_mips_elf_create_dynamic_sections): Adjust the call
to mips_elf_create_got_section.
(mips_elf_record_relocs): Likewise. Remove redundant
"dynobj == NULL" code. Do not use mips_elf_create_got_section
or mips_elf_record_global_got_symbol for R_MIPS_32, R_MIPS_REL32
and R_MIPS_64; limit global_got_area to GGA_RELOC_ONLY instead.
(_bfd_mips_elf_finish_dynamic_symbol): Use htab->sgot instead
of mips_elf_got_section.
(_bfd_mips_vxworks_finish_dynamic_symbol): Likewise.
(_bfd_mips_elf_finish_dynamic_sections): Likewise.
Move the initial assignment of G to the block that uses it;
it is used for an unrelated purpose later.
ld/testsuite/
* ld-mips-elf/tls-hidden4.got, ld-mips-elf/tls-hidden4.r: We have
removed an unused GOT entry that was allocated for the R_MIPS_32
relocation against "undef", so adjust addresses down by 4 bytes.
* ld-mips-elf/got-dump-1.d, ld-mips-elf/got-dump-2.d: We have
changed the order of the GOT entries so that reloc-only ones
come last. "undef" is only referred to by dynamic relocations,
so it now comes after "glob".
* ld-mips-elf/mips16-pic-2.dd, ld-mips-elf/mips16-pic-2.gd,
ld-mips-elf/mips16-pic-2.nd, ld-mips-elf/mips16-pic-2.rd: We have
removed two unused local GOT entries that were originally created
as global entries for the hidden symbols "used2" and "used3".
"used4" and "used5" are only referred to by relocations, so they
now come after "used6" and "used7".
* elfxx-mips.c (count_section_dynsyms): Move before the new first use.
(mips_elf_sort_hash_table): Take the output bfd as a parameter.
Remove the MAX_LOCAL parameter. Exit early if there are no
dynamic symbols, if there is no dynobj, or if there is no
GOT section. Use count_section_dynsyms instead of MAX_LOCAL.
Assert == rather than <= when checking hsd.max_unref_got_dynindx.
Also assert that g->global_gotno is right.
(mips_elf_count_forced_local_got_symbols): Rename to...
(mips_elf_count_got_symbols): ...and count global GOT entries too.
Set the global_got_area of a forced-local GGA_RELOC_ONLY symbol
to GGA_NONE.
(mips_elf_multi_got): Don't sort the symbol table.
(mips_elf_lay_out_got): Likewise. Use mips_elf_count_got_symbols
to count the number of global GOT entries.
(_bfd_mips_elf_final_link): Unconditionally call
mips_elf_sort_hash_table.
* elfxx-mips.c (GGA_NORMAL, GGA_RELOC_ONLY, GGA_NONE): New macros.
(mips_elf_link_hash_entry): Add a "global_got_area" field.
(mips_elf_link_hash_newfunc): Initialize it.
(mips_elf_sort_hash_table_f): Use h->global_got_area instead of
h->root.got.offset. Do not handle forced_local symbols specially.
(mips_elf_record_global_got_symbol): Set h->global_got_area
instead of h->root.got.offset.
(mips_elf_recreate_got): Assert that h->global_got_area == GGA_NONE
for indirect and warning symbols.
(mips_elf_count_forced_local_got_symbols): Change the argument
from a "elf_link_hash_entry" to "mips_elf_link_hash_entry".
Use and set h->global_got_area instead of h->root.got.offset.
Set it to GGA_NONE for all forced-local symbols.
(mips_elf_set_global_got_offset): Set h->global_got_area
instead of h->root.got.offset. Use g->global_got_area instead
of a combination of dynindx, forced_local and tls_type.
(mips_elf_multi_got): Remove disabled code. Pass GGA_* values to
mips_elf_set_global_got_offset.
(mips_elf_lay_out_got): Use mips_elf_link_hash_traverse instead
of elf_link_hash_traverse.
(_bfd_mips_elf_copy_indirect_symbol): Copy the indirect symbol's
global_got_area to the direct symbol if the latter's value is higher.
Set the indirect symbol's area to GGA_NONE.
