Add TLS support for 64-bit Sparc ELF.
* elf64-sparc.c (sparc64_elf_dyn_relocs,
sparc64_elf_link_hash_entry, sparc64_elf_obj_tdata): New structs.
(GOT_UNKNOWN, GOT_NORMAL, GOT_TLD_GD, GOT_TLD_IE,
sparc64_elf_hash_entry, sparc64_elf_tdata,
sparc64_elf_local_got_tls_type): New defines.
(sparc64_elf_mkobject): New function.
(sparc64_elf_link_hash_table): Add members for dynamic linker
sections PLT, RELPLT, DYNBSS, and RELBSS. Add tls_ldm_got
uion to track TLS GOT references. Add sym_sec to cache
mappings from local sym to section.
(link_hash_newfunc): New function.
(sparc64_elf_bfd_link_hash_table_create): Rename to
sparc64_elf_link_hash_table_create for consistency.
Pass link_hash_newfunc to _bfd_elf_link_hash_table_init.
(sparc64_elf_create_dynamic_sections): Initialize new section
members of sparc64_elf_link_hash_table. Only init srelbss
if not-shared.
(sparc64_elf_copy_indirect_symbol, sparc64_elf_tls_transition):
New functions.
(SPARC_NOP): Define.
(sparc64_elf_build_plt, sparc64_elf_plt_entry_offset,
sparc64_elf_plt_ptr_offset): Delete.
(sparc64_plt_entry_build): New function to build PLT entries
gradually instread of all at once at the end of linking.
(sparc64_elf_check_relocs): Delete dynobj, sgot, and srelgot
local vars. Get them from sparc64_elf_hash_table instead.
Check early on if r_symndx is in bounds. Handle TLS transitions.
Account for TLS GOT references and DF_STATIC_TLS, as needed.
For TLS relocs, record the tls_type in either
sparc64_elf_local_got_tls_type or sparc64_elf_hash_entry as
appropriate. For R_SPARC_TLS_{GD,LDM}_CALL, emit a reference
to the __tls_get_addr symbol. For PLT relocs, track references
via h->plt.refcount. When R_SPARC_{PC10,PC22,PC_HH22,PC_HM10,
PC_LM22} and h not-NULL, set h->non_got_ref. For global data
symbol references, count the number of relocations needed for
that symbol. For default switch case, don't error, this lets
the TLS relocs not explicitly handled by this function get
accepted.
(sparc64_elf_gc_mark_hook, sparc64_gc_sweep_hook): New functions.
(sparc64_elf_adjust_dynamic_symbol): Remove dynobj local var, get
it from sparc64_elf_hash_table. Store the real PLT offset
in h->plt.offset, and build PLT entries one at a time. Also
get .dynbss section pointer from htab.
(allocate_dynrelocs, readonly_dynrelocs,
sparc64_omit_section_dynsym): New functions.
(sparc64_elf_omit_section_dynsym): Use these new functions as
helpers.
(dtpoff_base, tpoff): New functions.
(sparc64_elf_relocate_section): Kill dynobj, sgot, and splt
locals, get them from sparc64_elf_hash_table. Handle TLS
relocations and refcounting in main relocation loop.
(sparc64_elf_finish_dynamic_symbol): Use
sparc64_elf_link_hash_table. Build PLT entries as we see
them. Handle TLS GOT relocations.
(sparc64_elf_finish_dynamic_sections): Get sgot and dynobj
from sparc64_elf_hash_table. Initialize only PLT header
not all entries since we not build PLT entries one by one.
(elf_backend_copy_indirect_symbol, bfd_elf64_mkobject,
elf_backend_gc_mark_hook, elf_backend_gc_sweep_hook,
elf_backend_can_gc_sections, elf_backend_can_refcount): Define.
ld/testsuite/
* ld-selective/sel-dump.exp: Do not exclude sparc64-*.
* ld-selective/selective.exp: Likewise.
* ld-sparc/sparc.exp: Add {32,64}-bit prefix to test
names so we know which one is failing. Run sparc64 TLS
tests on multi-arch sparc platforms.
* ld-sparc/tls64.sd, ld-sparc/tlssunbin64.dd,
ld-sparc/tlssunbin64.rd, ld/testsuite/ld-sparc/tlssunbin64.sd,
ld-sparc/tlssunbin64.td, ld-sparc/tlssunnopic64.dd,
ld-sparc/tlssunnopic64.rd, ld-sparc/tlssunnopic64.sd,
ld-sparc/tlssunpic64.dd, ld-sparc/tlssunpic64.rd,
ld-sparc/tlssunpic64.sd, ld-sparc/tlssunpic64.td): Update now
that sparc64 ELF does support TLS.
