Richard Sandiford 353057a53c * elf-bfd.h (eh_cie_fde): Add new fields: add_augmentation_size and
add_fde_encoding.  Remove need_relative.
	* elf-eh-frame.c (extra_augmentation_string_bytes)
	(extra_augmentation_data_bytes, size_of_output_cie_fde): New functions.
	(_bfd_elf_discard_section_eh_frame): Consider changing the FDE encoding
	in cases where the CIE has no existing 'R' augmentation.  Use
	size_of_output_cie_fde when assigning offsets.  Use the final offset
	as the new section size.
	(_bfd_elf_eh_frame_section_offset): Remove need_relative handling.
	Account for any extra augmentation bytes in the returned offset.
	(_bfd_elf_write_section_eh_frame): Rework so that the entries are
	moved before being modified.  Pad growing entries with DW_CFA_nops.
	Add 'z' and 'R' augmentations as directed by add_augmentation_size
	and add_fde_encoding.

Richard Sandiford f4a6705cf8 * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Deal with
composite relocations against the personality data.
2004-11-15 09:09:13 +00:00
Alan Modra 92e4ec35d9 * elf-eh-frame.c (_bfd_elf_eh_frame_section_offset): Add "info"
parameter.  If called after _bfd_elf_write_section_eh_frame,
	don't allow a -2 return unless need_* bit is already set, and
	handle offsets adjusted for output_offset.
	* elf-bfd.h (_bfd_elf_eh_frame_section_offset): Update prototype.
	* elf.c (_bfd_elf_section_offset): Update call.
2004-10-14 23:38:08 +00:00
Alan Modra 3472e2e999 * elf-bfd.h (struct eh_frame_hdr_info): Add offsets_adjusted.
* elf-eh-frame.c (_bfd_elf_write_section_eh_frame): Adjust
	offsets stored in struct eh_cie_fde entries before doing other
	work.
2004-10-10 13:02:01 +00:00
Alan Modra fda3ecf23f * elf-bfd.h (struct eh_cie_fde): Add cie_inf, remove sec.
(struct eh_frame_hdr_info): Add last_cie_inf, remove last_cie_offset.
	* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete code
	setting offsets for removed CIEs.  Don't set "sec", instead set
	cie_inf for FDEs.  Keep a pointer to last struct eh_cie_fde for a
	CIE in hdr_info.  Only set make_relative and make_lsda_relative
	for CIEs.  Use pointers rather than array indices.
	(_bfd_elf_eh_frame_section_offset): Test/set make_relative,
	make_lsda_relative, need_* on cie_inf for FDEs.
	(_bfd_elf_write_section_eh_frame): Adjust offset and new_offset for
	section output_offset.  Delete cie_offset, instead use cie_inf
	pointer to CIE entry.  Use need_relative and need_lsda_relative on
	CIE entry for FDEs.  Use pointers rather than array indices.

Alan Modra 8935b81f1f * elf-bfd.h (struct eh_cie_fde): Add need_relative and
need_lsda_relative.
	* elf-eh-frame.c (_bfd_elf_eh_frame_section_offset): Set
	need_relative or need_lsda_relative if we are processing an
	offset for a reloc on a FDE initial loc or LSDA field
	respectively.
	(_bfd_elf_write_section_eh_frame): Test need_relative and
	need_lsda_relative in place of corresponding make_* field
	when deciding to use pc-relative encodings.

* 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".
