8519ea2120 * elflink.h (elf_link_output_extsym): Call finish_dynamic_symbol
for a symbol which is being forced to be local.
	* elf32-i386.c (elf_i386_relocate_section): Write out the
 	relocation value for a GOT reloc for a symbol which is turning
 	into a local symbol.
	(elf_i386_finish_dynamic_symbol): If a symbol is turning into a
	local symbol, write out a RELATIVE reloc rather than a GLOB_DAT
	reloc.
	* elf32-m68k.c, elf32-sparc.c: Corresponding changes.

elf64-alpha multiple .got rewrite:

	* elf-bfd.h (struct elf_backend_data): Add always_size_sections entry.
	(bfd_elf*_mkobject): Don't define here ...
	* elfxx-target.h: ... but rather here.  Default always_size_sections
	hook to NULL.
	* elf.c (elf_mkobject): Rename to bfd_elf_mkobject, since that was
	what the #defines in elf-bfd.h transmuted it to anyway.

	* section.c: Add SEC_LINKER_CREATED flag.
	* bfd-in2.h: Rebuild.
	* elf32-i386.c (elf_i386_check_relocs): Add SEC_LINKER_CREATED to
	relocation section flags.
	(elf_i386_size_dynamic_sections): Use SEC_LINKER_CREATED instead of
	SEC_IN_MEMORY to recognize generated bits.
	* elf32-m68k.c (elf_m68k_check_relocs, elf_m68k_size_dynamic_sections):
	Likewise.
	* elf32-mips.c (mips_elf_final_link, mips_elf_create_dynamic_sections,
	mips_elf_create_compact_rel_section, mips_elf_create_got_section,
	mips_elf_check_relocs, mips_elf_size_dynamic_sections): Likewise.
	* elf32-ppc.c (ppc_elf_create_linker_section,
	ppc_elf_size_dynamic_sections): Likewise.
	* elf32-sparc.c (elf32_sparc_check_relocs,
	elf32_sparc_size_dynamic_sections): Likewise.
	* elflink.c (_bfd_elf_create_got_section): Add SEC_LINKER_CREATED to
	section flags.
	(_bfd_elf_create_dynamic_sections): Likewise.
	(_bfd_elf_make_linker_section_rela): Likewise.
	* elflink.h (elf_link_create_dynamic_sections): Likewise.
	(bfd_elf,size_dynamic_sections): Call the always_size_sections hook.
	(elf_bfd_final_link): Use SEC_LINKER_CREATED instead of SEC_IN_MEMORY
	to identify generated bits.
	(elf_link_input_bfd): Likewise.

	* elf64-alpha.c: Rewrite everything touching relocations.

53787b2316 * elf32-i386.c (elf_i386_relocate_section): If -Bsymbolic, when
copying relocs into a shared object, treat a defined global symbol
	as a local symbol.

943fbd5bd5 fsf address update, but not in COPYING files 1995-07-07 22:49:42 +00:00

ede4eed483 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.
