(ppc64_elf_copy_indirect_symbol): New function.
(ppc64_elf_check_relocs): Remove DEBUG code. Use short-cuts to
dynamic sections. Localise vars. Modify code for refcounts
starting from zero. Don't allocate here, or force symbols dynamic.
Don't copy all relocs if shared, select ones we need. Add code
to track possible copy relocs for non-shared link.
(ppc64_elf_gc_mark_hook): Update comment.
(ppc64_elf_gc_sweep_hook): Sweep dynrelocs too.
(ppc64_elf_adjust_dynamic_symbol): Remove DEBUG code. Rewrite .plt
code for reference counting garbage collection. Don't create .plt
entries for functions that don't comply with ABI naming convention,
and don't allocate .plt space here. Use short-cuts to dynamic
sections. If possible, keep dynamic relocations instead of using

space here, and call allocate_dynrelocs to allocate space for
global .plt, .got and reloc sections. Use short-cuts to dynamic
sections. Call readonly_dynrelocs to determine whether we need
DT_TEXTREL. Don't generate section symbols here, the generic
ELF linker code does it for us.
(ppc64_elf_final_link): Call regular ELF backend linker rather than
gc variety, since we do our own .got handling.
(ppc64_elf_relocate_section): Remove DEBUG code. Make use of
dynamic section short-cuts. Localise vars, and delay setting.
Handle unknown relocs in main switch statement. Replace ugly
complicated tests for unresolvable relocs with a simple direct
scheme using "unresolved_reloc" var. Test ELF_ST_VISIBILITY
before allowing an undefined sym in a shared lib. Do R_*_DS tests
after main switch, when we've set addend. Do non-addend insn
tweaks before main swithc. Ignore input_section->vma when
calculating reloc offsets as it's always zero. Rewrite dynamic
reloc handling. Consolidate R_*_HA handling. Handle more relocs.
(ppc64_elf_finish_dynamic_symbol): Remove DEBUG code. Make use
of dynamic section short-cuts. Reorganise .plt handling code.
Remove confused comments. Take note of ELF_LINK_FORCED_LOCAL.
Move expressions out of swap_reloca_out function calls.

/* The following functions are specific to the ELF linker, while
|
|
|
|
|
functions above are used generally. Those named ppc64_elf_* are
|
|
|
|
|
called by the main ELF linker code. They appear in this file more
|
|
|
|
|
or less in the order in which they are called. eg.
|
|
|
|
|
ppc64_elf_check_relocs is called early in the link process,
|
|
|
|
|
ppc64_elf_finish_dynamic_sections is one of the last functions
|
2002-01-21 13:15:07 +01:00
|
|
|
|
called.
|
|
|
|
|
|
|
|
|
|
PowerPC64-ELF uses a similar scheme to PowerPC64-XCOFF in that
|
|
|
|
|
functions have both a function code symbol and a function descriptor
|
|
|
|
|
symbol. A call to foo in a relocatable object file looks like:
|
|
|
|
|
|
|
|
|
|
. .text
|
|
|
|
|
. x:
|
|
|
|
|
. bl .foo
|
|
|
|
|
. nop
|
|
|
|
|
|
|
|
|
|
The function definition in another object file might be:
|
|
|
|
|
|
|
|
|
|
. .section .opd
|
|
|
|
|
. foo: .quad .foo
|
|
|
|
|
. .quad .TOC.@tocbase
|
|
|
|
|
. .quad 0
|
|
|
|
|
.
|
|
|
|
|
. .text
|
|
|
|
|
. .foo: blr
|
|
|
|
|
|
|
|
|
|
When the linker resolves the call during a static link, the branch
|
|
|
|
|
unsurprisingly just goes to .foo and the .opd information is unused.
|
|
|
|
|
If the function definition is in a shared library, things are a little
|
|
|
|
|
different: The call goes via a plt call stub, the opd information gets
|
|
|
|
|
copied to the plt, and the linker patches the nop.
|
|
|
|
|
|
|
|
|
|
. x:
|
|
|
|
|
. bl .foo_stub
|
|
|
|
|
. ld 2,40(1)
|
|
|
|
|
.
|
|
|
|
|
.
|
|
|
|
|
. .foo_stub:
|
|
|
|
|
. addis 12,2,Lfoo@toc@ha # in practice, the call stub
|
|
|
|
|
. addi 12,12,Lfoo@toc@l # is slightly optimised, but
|
|
|
|
|
. std 2,40(1) # this is the general idea
|
|
|
|
|
. ld 11,0(12)
|
|
|
|
|
. ld 2,8(12)
|
|
|
|
|
. mtctr 11
|
|
|
|
|
. ld 11,16(12)
|
|
|
|
|
. bctr
|
|
|
|
|
.
|
|
|
|
|
. .section .plt
|
|
|
|
|
. Lfoo: reloc (R_PPC64_JMP_SLOT, foo)
|
|
|
|
|
|
|
|
|
|
The "reloc ()" notation is supposed to indicate that the linker emits
|
|
|
|
|
an R_PPC64_JMP_SLOT reloc against foo. The dynamic linker does the opd
|
|
|
|
|
copying.
|
|
|
|
|
|
|
|
|
|
What are the difficulties here? Well, firstly, the relocations
|
|
|
|
|
examined by the linker in check_relocs are against the function code
|
|
|
|
|
sym .foo, while the dynamic relocation in the plt is emitted against
|
|
|
|
|
the function descriptor symbol, foo. Somewhere along the line, we need
|
|
|
|
|
to carefully copy dynamic link information from one symbol to the other.
|
|
|
|
|
Secondly, the generic part of the elf linker will make .foo a dynamic
|
|
|
|
|
symbol as is normal for most other backends. We need foo dynamic
|
|
|
|
|
instead, at least for an application final link. However, when
|
|
|
|
|
creating a shared library containing foo, we need to have both symbols
|
|
|
|
|
dynamic so that references to .foo are satisfied during the early
|
|
|
|
|
stages of linking. Otherwise the linker might decide to pull in a
|
2002-01-23 12:21:18 +01:00
|
|
|
|
definition from some other object, eg. a static library. */

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.

/* If we are creating a shared library, and this is a reloc
|
|
|
|
|
against a global symbol, or a non PC relative reloc
|
|
|
|
|
against a local symbol, then we need to copy the reloc
|
|
|
|
|
into the shared library. However, if we are linking with
|
|
|
|
|
-Bsymbolic, we do not need to copy a reloc against a
|
|
|
|
|
global symbol which is defined in an object we are
|
|
|
|
|
including in the link (i.e., DEF_REGULAR is set). At
|
|
|
|
|
this point we have not seen all the input files, so it is
|
|
|
|
|
possible that DEF_REGULAR is not set now but will be set
|
|
|
|
|
later (it is never cleared). In case of a weak definition,
|
|
|
|
|
DEF_REGULAR may be cleared later by a strong definition in
|
|
|
|
|
a shared library. We account for that possibility below by
|
|
|
|
|
storing information in the relocs_copied field of the hash
|
|
|
|
|
table entry. A similar situation occurs when creating
|
|
|
|
|
shared libraries and symbol visibility changes render the
|
|
|
|
|
symbol local.
|
|
|
|
|
|
|
|
|
|
If on the other hand, we are creating an executable, we
|
|
|
|
|
may need to keep relocations for symbols satisfied by a
|
|
|
|
|
dynamic library if we manage to avoid copy relocs for the
|
|
|

symbol. */

Handle unknown relocs in main switch statement. Replace ugly
complicated tests for unresolvable relocs with a simple direct

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

o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

(ppc64_elf_check_relocs): Remove DEBUG code. Use short-cuts to
dynamic sections. Localise vars. Modify code for refcounts
starting from zero. Don't allocate here, or force symbols dynamic.
Don't copy all relocs if shared, select ones we need. Add code
to track possible copy relocs for non-shared link.
(ppc64_elf_gc_mark_hook): Update comment.
(ppc64_elf_gc_sweep_hook): Sweep dynrelocs too.
(ppc64_elf_adjust_dynamic_symbol): Remove DEBUG code. Rewrite .plt
code for reference counting garbage collection. Don't create .plt
entries for functions that don't comply with ABI naming convention,
and don't allocate .plt space here. Use short-cuts to dynamic
sections. If possible, keep dynamic relocations instead of using
copy relocs. Remove confused comments.
(ppc_adjust_dynindx): Delete.
(WILL_CALL_FINISH_DYNAMIC_SYMBOL): Define.
(allocate_dynrelocs): New function.
(readonly_dynrelocs): New function.
(ppc64_elf_size_dynamic_sections): Rewrite. Allocate local .got
space here, and call allocate_dynrelocs to allocate space for
global .plt, .got and reloc sections. Use short-cuts to dynamic
sections. Call readonly_dynrelocs to determine whether we need
DT_TEXTREL. Don't generate section symbols here, the generic
ELF linker code does it for us.
(ppc64_elf_final_link): Call regular ELF backend linker rather than
gc variety, since we do our own .got handling.
(ppc64_elf_relocate_section): Remove DEBUG code. Make use of
dynamic section short-cuts. Localise vars, and delay setting.
Handle unknown relocs in main switch statement. Replace ugly
complicated tests for unresolvable relocs with a simple direct
scheme using "unresolved_reloc" var. Test ELF_ST_VISIBILITY
before allowing an undefined sym in a shared lib. Do R_*_DS tests
after main switch, when we've set addend. Do non-addend insn
tweaks before main swithc. Ignore input_section->vma when
calculating reloc offsets as it's always zero. Rewrite dynamic
reloc handling. Consolidate R_*_HA handling. Handle more relocs.
(ppc64_elf_finish_dynamic_symbol): Remove DEBUG code. Make use
of dynamic section short-cuts. Reorganise .plt handling code.
Remove confused comments. Take note of ELF_LINK_FORCED_LOCAL.
Move expressions out of swap_reloca_out function calls.
(ppc64_elf_reloc_type_class): New function.
(ppc64_elf_info_to_howto): Move common expression to local var.
(ppc64_elf_finish_dynamic_sections): Remove DEBUG code. Make use
of dynamic section short-cuts. Don't fiddle with section syms
here as the ELF linker does it for us.

/* 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
|
|
|
|
|
relocateable output file) adjusting the reloc addend as
|
|
|
|
|
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).
|
|
|
|
|
|
|
|
|
|
When generating relocateable output, this function must handle
|
|
|
|
|
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. */

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.

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.
