+
+ * 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.
