/* This structure contains everything that BFD knows about a target.
|
|
|
|
|
It includes things like its byte order, name, what routines to call
|
|
|
|
|
to do various operations, etc. Every BFD points to a target structure
|
|
|
|
|
with its "xvec" member.
|
|
|
|
|
|
|
|
|

There are two such structures here: one for big-endian machines and

|
|
|
|
one for little-endian machines. */

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

realloc failure.
(elf_fake_sections): Check return value of bfd_add_to_strtab.
(elf_compute_section_file_positions): Add link_info argument.
Call elf_backend_begin_write_processing hook and prep_headers
here. Only call swap_out_syms if link_info is NULL. Set up
.shstrtab section here. Pass dosyms argument to
assign_file_positions_except_relocs. Set output_has_begun flag.
(assign_file_positions_for_symtab_and_strtabs): Add dosyms
argument, and use it to control setting .symtab and .strtab file
positions.
(assign_file_positions_except_relocs): Add dosyms argument, and
pass it on.
(prep_headers): Check return value of bfd_add_to_strtab.
(swap_out_syms): Likewise. Also, don't set up .shstrtab here.
(NAME(bfd_elf,write_object_contents)): Some calls moved into
elf_compute_section_file_positions.
(elf_set_section_contents): Likewise.
(elf_slurp_symbol_table): SHN_LORESERV corrected to SHN_LORESERVE.
* libelf.h: Include bfdlink.h.
(struct elf_backend_data): Add fields collect,
elf_add_symbol_hook, elf_backend_relocate_section.
(struct bfd_elf_section_data): Add field rel_hashes.
(struct elf_obj_tdata): Remove fields internal_syms and symbols.
Add field sym_hashes.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.

Added new files elflink.c, elflink.h, elfcore.h.
Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data
structure to elfcode.h with some misc data and callback functions. Added a
pointer to that structure to the target back end data. More work can be done
here.
Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or
_bfd_elf. Updated most call sites, sometimes defined some macros.
Moved some dynamic linking support code from m68k, sparc, i386 to common files,
using target back end flags to control behavior. More work can probably be
done here too.
Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h,
elflink.h, or elflink.c. Now elfcode.h contains only .o and executable
support, plus #includes of elfcore.h and elflink.h. Much of the contents of
these other header files can probably still be moved from the .h files to the
.c files, to get compiled only once.
Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized
variables, in generic and cpu-specific code.
