7619e7c7de * elf32-ppc.h: New file.
* elf32-ppc.c: Include elf32-ppc.h.
	(NOP, CROR_151515, CROR_313131, TP_OFFSET, DTP_OFFSET): Define.
	(struct ppc_elf_link_hash_entry): Rename "root" to "elf".  Adjust uses.
	Add "tls_mask" field.
	(TLS_GD, TLS_LD, TLS_TPREL, TLS_DTPREL, TLS_TLS, TLS_TPRELGD): Define.
	(struct ppc_elf_link_hash_table): Rename "root" to "elf".  Adjust uses.
	Add got, relgot, plt, relplt, dynbss, relbss, dynsbss, relsbss,
	sdata, sdata2, tls_sec, tls_get_addr, tlsld_got fields.
	Make use of htab shortcuts throughout file.
	(ppc_elf_link_hash_newfunc): Init tls_mask field.
	(ppc_elf_link_hash_table_create): Init new fields.
	(ppc_elf_copy_indirect_symbol): Copy tls_mask.
	(ppc_elf_howto_raw): Add tls relocs.
	(ppc_elf_reloc_type_lookup): Handle them.
	(ppc_elf_unhandled_reloc): New function.
	(ppc_elf_create_got): Stash got section pointer in hash table,
	return status.  Make .rela.got too.
	(ppc_elf_create_dynamic_sections): Stash section pointers in htab.
	(ppc_elf_adjust_dynamic_symbol): Only set up copy relocs when
	NON_GOT_REF set.  Don't allocate space in .plt here..
	(allocate_dynrelocs): ..do so here instead, properly ref-counting and
	not allocating plt entries unnecessarily.  Allocate got entries here.
	(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Define.
	(ppc_elf_size_dynamic_sections): Allocate local got entries.  Pass
	"info" during allocate_dynrelocs hash traversal.  Use htab section
	shortcuts rather than searching for named sections.  Get rid of
	"plt" and "strip" booleans.
	(update_local_sym_info, bad_shared_reloc): New functions.
	(ppc_elf_check_relocs): Handle TLS relocs.  Move .rela.got creation to
	ppc_elf_create_got.  Don't mark got or plt reloc syms dynamic, do so
	in allocate_dynreloc.  Use update_local_sym_info and bad_shared_reloc.
	Disallow R_PPC_EMB_RELSDA, R_PPC_EMB_NADDR32, R_PPC_EMB_NADDR16,
	R_PPC_EMB_NADDR16_LO, R_PPC_EMB_NADDR16_HI and R_PPC_EMB_NADDR16_HA
	in shared libs.  R_PPC_PLTREL32 is a plt reloc too.  Refcount all
	relocs that might use a plt entry.  Set NON_GOT_REF too.
	Enumerate all do-nothing relocs.
	(ppc_elf_gc_sweep_hook): Simplify removal of dynrelocs.  Handle
	tls relocs and all plt relocs.
	(ppc_elf_tls_setup, ppc_elf_tls_optimize): New functions.
	(ppc_elf_finish_dynamic_symbol): Don't build got entries here.
	(ppc_elf_finish_dynamic_sections): Rewrite tag code using htab
	shortcuts.
	(ppc_elf_relocate_section): Tidy.  Handle TLS relocs.  Use
	bfd_elf_local_sym_name.  Simplify unresolved reloc code.  Build got
	entries and got relocs here.  Warn on non-zero got reloc addend.
	Split out branch taken/not taken reloc code into a separate switch
	and correct offset calculation. Allow BRTAKEN/BRNTAKEN dynamic relocs.
	Split out HA reloc adjustments to separate switch statement.  Don't
	warn on reloc overflow if we've already warned about undefined.
	Don't rebuild sym name when reporting errors.  Report all possible
	errors from _bfd_final_link_relocate.
	(bfd_elf32_bfd_final_link): Don't define.
