Subject: 	* elf.c (elf_fake_sections): When calculating tbss size, just use
X-Git-Tag: gdb-csl-20060226-branchpoint~862
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3a800eb947748a8cad1b13ed485b5dce1b4cfc4b;p=platform%2Fupstream%2Fbinutils.git

	* elf.c (elf_fake_sections): When calculating tbss size, just use
	the last link_order.
	(assign_file_positions_for_segments): Likewise.
	* elflink.c (bfd_elf_final_link): Likewise.
	(elf_reloc_link_order): Correct comment.
