Do not make them dynamic for read-only sections in non-PIC executable objects. Do not protect this code with dynobj == NULL || htab->sgot == NULL; handle each group of cases separately.

Complain if we find a static-only reloc against an externally-defined symbol and if we cannot create dynamic relocations for it.

(_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols instead of mips_elf_check_mips16_stubs to process each symbol. Do the traversal for relocatable objects too. (mips_elf_lay_out_got): Use htab->reserved_gotno instead of MIPS_RESERVED_GOTNO. (_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it is empty. Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling to non-VxWorks targets. Only add DT_REL{,A}, DT_REL{,A}SZ and DT_REL{,A}ENT if .rel.dyn is nonempty. Create a symbol for the PLT.

# The first test checks that a mixed PIC/non-PIC relocatable link
# will not introduce any stubs itself, but will flag PIC functions
# for the final link.
#
# The second test checks that we insert stubs for calls from
# non-PIC functions to PIC functions when linking the original
# two objects together.
#
# The third test checks that we do the same when linking the
# result of the first link (with no other source files).

(_bfd_mips_elf_final_link): Use count_section_dynsyms. ld/testsuite/ * ld-mips-elf/stub-dynsym-1.s, * ld-mips-elf/stub-dynsym-1.ld, * ld-mips-elf/stub-dynsym-1-7fff.d, * ld-mips-elf/stub-dynsym-1-8000.d, * ld-mips-elf/stub-dynsym-1-fff0.d, * ld-mips-elf/stub-dynsym-1-10000.d, * ld-mips-elf/stub-dynsym-1-2fe80.d: New test. * ld-mips-elf/mips-elf.exp: Run it.

bfd/ * 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. ld/testsuite/ * ld-mips-elf/got-vers-1a.s, ld-mips-elf/got-vers-1b.s, ld-mips-elf/got-vers-1.ver, ld-mips-elf/got-vers-1.dd, ld-mips-elf/got-vers-1.sd, ld-mips-elf/got-vers-1.rd: New tests. * ld-mips-elf/mips-elf.exp: Run them.
