(ppc64_elf_check_relocs): Use it. Correct comment. Move SEC_ALLOC
test.
(ppc64_elf_adjust_dynamic_symbol): Use ELIMINATE_COPY_RELOCS.
(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Pass SHARED instead of INFO.
(allocate_dynrelocs): Adjust WILL_CALL_FINISH_DYNAMIC_SYMBOL uses,
and optimize. Use ELIMINATE_COPY_RELOCS.
(ppc64_elf_relocate_section): Likewise.
(ppc_elf_copy_indirect_symbol): Copy pc_count field.
(ELIMINATE_COPY_RELOCS): Define.
(ppc_elf_adjust_dynamic_symbol): Convert copy relocs to dynamic.
(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Pass SHARED instead of INFO.
(MUST_BE_DYN_RELOC): Define.
(allocate_dynrelocs): Adjust WILL_CALL_FINISH_DYNAMIC_SYMBOL uses,
and optimize. Trim dyn_relocs.
(ppc_elf_check_relocs): Don't generate dyn_relocs when we know they'll
not be used. Do generate dyn_relocs for copy reloc avoidance. Keep
track of pc_rel dyn relocs.
(ppc_elf_relocate_section): Remove "will_become_local". Adjust
WILL_CALL_FINISH_DYNAMIC_SYMBOL use. Trim dyn relocs as per
allocate_dynrelocs. Don't recalculate "sec".
From Jim Ingham <jingham@apple.com>:
* dbxread.c (process_one_symbol): Use last_function_start rather
than function_start_offset to find the real beginning of the
current function. The latter is just the text section offset on
some systems, the former is always the real function start.
* elf64-ppc.c (ppc64_elf_tls_optimize): Decrement tlsld_got.refcount
on invalid LD relocs.
(allocate_dynrelocs): Invalid LD relocs don't use tlsld_got entry.
(ppc64_elf_relocate_section): Unify new handling of LD relocs and
tlsld_got entry. Use IS_PPC64_TLS_RELOC.
* 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.
* configure.in (Makefile): Use the test ${target} != ${host},
instead of the absence of the "nm.h" file, to determine of the
configuration non-native.
* configure: Regenerate.
2003-02-12 Jason Molenda (jmolenda@apple.com)
* symmisc.c (print_objfile_statistics): Include information about
the number of psymtabs and symtabs in each object file.
[testsuite/ChangeLog]
2003-02-13 Jason Molenda (jmolenda@apple.com)
* gdb.base/maint.exp: Update maint print statistics regexp to include
new entries.
(ppc64_elf_copy_indirect_symbol): Merge tls_mask too.
(ppc64_elf_gc_sweep_hook): Simplify removal of dyn_relocs.
(allocate_dynrelocs): Don't treat undefined and undefweak specially.
(ppc_size_one_stub): Fix warning, and tighten plt entry check.
(group_sections): Don't share a stub section if stubs are for a large
section. Adjust comment.
(ppc64_elf_size_stubs): Roughly double the size left for stubs if
!stubs_always_before_branch.
(ppc64_elf_relocate_section): Initialize tlsld GOT entry once. Don't
treat undefined and undefweak specially when processing dyn relocs.
