* 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.

(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.

bfd/
* section.c (struct sec): Rename "_cooked_size" to "size".
Rename "_raw_size" to "rawsize".
(STD_SECTION): Adjust comments.
(bfd_set_section_size, bfd_get_section_contents): Use size.
(bfd_malloc_and_get_section): New function.
* bfd-in.h (bfd_section_size, bfd_get_section_size): Use size.
* coff-sh.c (sh_relax_section): Alloc coff_section_data struct early.
Correctly free reloc and contents memory.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME
and fake CIE now that we can shink section size to zero.
(_bfd_elf_write_section_eh_frame): Likewise..
* elf32-ppc.c (ppc_elf_relax_section): Delay reading section contents.
* elf-m10300.c (mn10300_elf_final_link_relocate): Don't use
_bfd_stab_section_offset. Use _bfd_elf_section_offset.
* stabs.c (_bfd_stab_section_offset_): Remove unused args and
unneeded indirection.
* elf.c (_bfd_elf_section_offset): .. and update call.
* libbfd-in.h (_bfd_stab_section_offset): Update prototype.
* libbfd.h: Regenerate.
* bfd-in2.h: Regenerate.
Replace occurrences of "_raw_size" and "_cooked_size" in most places
with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE
sections. Use "rawsize", if non-zero, for bfd_get_section_contents
calls if the section might be a stabs, eh_frame, or SEC_MERGE section.
Similarly use "rawsize", if non-zero, in reloc functions to validate
reloc addresses. Use new bfd_malloc_and_get_section in most places
where bfd_get_section_contents was called. Expand all occurrences of
bfd_section_size and bfd_get_section_size. Rename "raw_size" var in
grok_prstatus and similar functions to "size".

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.

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.

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.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

(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.

/* The RELOCATE_SECTION function is called by the ELF backend linker
|
|
|
|
|
to handle the relocations for a section.
|
|
|
|
|
|
|
|
|
|
The relocs are always passed as Rela structures; if the section
|
|
|
|
|
actually uses Rel structures, the r_addend field will always be
|
|
|
|
|
zero.
|
|
|
|
|
|
|
|
|
|
This function is responsible for adjust the section contents as
|
|
|
|
|
necessary, and (if using Rela relocs and generating a
|
2003-06-25 08:40:27 +02:00
|
|
|
|
relocatable output file) adjusting the reloc addend as
|
1999-05-03 09:29:11 +02:00
|
|
|
|
necessary.
|
|
|
|
|
|
|
|
|
|
This function does not have to worry about setting the reloc
|
|
|
|
|
address or the reloc symbol index.
|
|
|
|
|
|
|
|
|
|
LOCAL_SYMS is a pointer to the swapped in local symbols.
|
|
|
|
|
|
|
|
|
|
LOCAL_SECTIONS is an array giving the section in the input file
|
|
|
|
|
corresponding to the st_shndx field of each local symbol.
|
|
|
|
|
|
|
|
|
|
The global hash table entry for the global symbols can be found
|
|
|
|
|
via elf_sym_hashes (input_bfd).

|
|
|
|
2003-06-25 08:40:27 +02:00

|
1999-05-03 09:29:11 +02:00
|
|
|
|
STB_LOCAL/STT_SECTION symbols specially. The output symbol is
|
|
|
|
|
going to be the section symbol corresponding to the output
|
|
|
|
|
section, which means that the addend must be adjusted
|
|
|
|
|
accordingly. */

* 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.

(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.
