Re: PATCH: Symbian OS linker scripts


Hi Mark,

This patch adds (the beginnings of) ARM Symbian OS support to ld.

OK?

2004-09-01 Mark Mitchell <mark@codesourcery.com>

	* config.bfd (arm*-*-symbianelf*): Use OS-specific target vectors.
	* configure.in (bfd_elf32_bigarm_symbian_vec): Add it.
	(bfd_elf32_littlearm_symbian_vec): Likewise.
	* configure: Regenerated.
	* elf-bfd.h (elf_backend_data): Add dynamic_sec_flags.
	* elf32-arm.h (PLT_HEADER_SIZE): Do not define.
	(PLT_ENTRY_SIZE): Likewise.
	(bfd_vma_elf32_arm_multiple_address_space_dll_plt_entry): New
	variable.
	(elf32_arm_link_hash_table): Add plt_header_size, plt_entry_size,
	and multiple_address_space_dll_p.
	(create_got_section): Don't create sections when generating BPABI
	objects.
	(elf32_arm_create_dynamic_sections): Don't create .rel.plt section
	when generating BPABI objects.
	(elf32_arm_link_hash_table_create): Set plt_header_size,
	plt_entry_size, and multiple_address_space_dll_p.
	(elf32_arm_check_relocs): Do not mark .rel.dyn as loadable when
	generating BPABI objects.
	(allocate_dynrelocs): Use htab->plt_header_size, not
	PLT_HEADER_SIZE.  Do not add to .got.plt or .rel.plt when
	generating BPABI objects.
	(elf32_arm_finish_dynamic_symbol): Generate Symbian OS PLTs.
	* elfarm-nabi.c: Add SymbianOS target vectors.
	* elflink.c (_bfd_elf_create_got_section): Use dynamic_sec_flags.
	(_bfd_elf_link_create_dynamic_sections): Likewise.
