Simon Dardis 40fc1451c6 [MIPS] Map 'move' to 'or'.
The MIPS assembly idiom 'move' now maps to the 'or' machine instruction. This
change affects microMIPS, MIPS32, MIPS64.

2015-08-12  Simon Dardis  <simon.dardis@imgtec.com>

	* micromips-opc.c (micromips_opcodes): Re-order table so that move
	based on 'or' is first.

	(mips_elf_link_hash_table): Add blank lines.  Add
	"use_plts_and_copy_relocs", "reserved_gotno", "strampoline",
	"la25_stubs" and "add_stub_section" fields.
	(mips_htab_traverse_info): New structure.
	(PIC_OBJECT_P, MIPS_ELF_LOAD_WORD): New macros.
	(MIPS_RESERVED_GOTNO): Delete.
	(mips_o32_exec_plt0_entry, mips_n32_exec_plt0_entry)

	(mips_elf_link_hash_newfunc): Update after the changes to
	mips_elf_link_hash_entry.
	(mips_elf_check_mips16_stubs): Replace the DATA parameter with
	an INFO parameter.  Don't look through warnings symbols here;
	do it in mips_elf_check_symbols instead.
	(mips_elf_create_stub_symbol): New function.
	(mips_elf_la25_stub_hash, mips_elf_la25_stub_eq): New functions.
	(_bfd_mips_elf_init_stubs, mips_elf_local_pic_function_p): Likewise.
	(mips_elf_add_la25_intro, mips_elf_add_la25_trampoline): Likewise.
	(mips_elf_add_la25_stub, mips_elf_check_symbols): New functions.
	(mips_elf_gotplt_index): Check for VxWorks.
	(mips_elf_output_dynamic_relocation): Take the relocation index
	as an extra parameter.  Do not increment reloc_count here.
	(mips_elf_initialize_tls_slots): Update the calls to
	mips_elf_output_dynamic_relocation accordingly.
	(mips_elf_multi_got): Use htab->reserved_gotno instead of
	MIPS_RESERVED_GOTNO.
	(mips_elf_create_got_section): Don't allocate reserved GOT
	entries here.  Unconditionally create .got.plt, but don't
	set its alignment here.
	(mips_elf_relocation_needs_la25_stub): New function.
	(mips_elf_calculate_relocation): Redirect branches and jumps to
	a non-PIC stub if one exists.  Check !h->has_static_relocs instead
	of !htab->is_vxworks when deciding whether to create dynamic
	relocations for R_MIPS_32, R_MIPS_REL32 and R_MIPS_64.
	(_bfd_mips_elf_create_dynamic_sections): Unconditionally call
	_bfd_elf_create_dynamic_sections.  Unconditionally set up
	htab->splt and htab->sdynbss.  Set htab->srelplt to ".rel.plt"
	if !htab->is_vxworks.  Add non-VxWorks values of
	htab->plt_header_size and htab->plt_entry_size.
	(_bfd_mips_elf_check_relocs): Set pointer_equality_needed for
	non-branch static relocations.  Set has_nonpic_branches when an la25
	stub might be required.  Set can_make_dynamic_p to TRUE if R_MIPS_32,
	R_MIPS_REL32 and R_MIPS_64 relocations can be made dynamic,
	rather than duplicating the condition.  Do not make them dynamic
	for read-only sections in non-PIC executable objects.
	Do not protect this code with dynobj == NULL || htab->sgot == NULL;
	handle each group of cases separately.  Add a default case that
	sets has_static_relocs for non-GOT relocations that cannot be
	made dynamic.  Don't set is_relocation_target and is_branch_target.
	Reject non-PIC static relocations in shared objects.
	(_bfd_mips_vxworks_adjust_dynamic_symbol): Fold into...
	(_bfd_mips_elf_adjust_dynamic_symbol): ...here, using
	htab->use_plts_and_copy_relocs instead of htab->is_vxworks
	to select PLT and copy-reloc handling.  Set the alignment of
	.plt and .got.plt when allocating the first entry.  Generalize
	code to handle REL as well as RELA sections and 64-bit as well as
	32-bit GOT entries.  Complain if we find a static-only reloc
	against an externally-defined symbol and if we cannot create
	dynamic relocations for it.  Allocate copy relocs using
	mips_elf_allocate_dynamic_relocations on non-VxWorks targets.
	Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs.
	Skip reserved .got.plt entries.
	(_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols
	instead of mips_elf_check_mips16_stubs to process each symbol.
	Do the traversal for relocatable objects too.
	(mips_elf_lay_out_got): Use htab->reserved_gotno instead of
	MIPS_RESERVED_GOTNO.
	(_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it
	is empty.  Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling
	to non-VxWorks targets.  Only add DT_REL{,A}, DT_REL{,A}SZ and
	DT_REL{,A}ENT if .rel.dyn is nonempty.  Create a symbol for the
	PLT.  Allocate a nop at the end of the PLT.  Allocate DT_MIPS_PLTGOT.
	(mips_elf_create_la25_stub_info): New function.
	(_bfd_mips_elf_finish_dynamic_symbol): Write out PLT entries
	and copy relocs where necessary.  Check pointer_equality_needed.
	(mips_finish_exec_plt): New function.
	(_bfd_mips_elf_finish_dynamic_sections): Always set DT_PLTGOT
	to the beginning of htab->sgot.  Use htab->reserved_gotno instead
	of MIPS_RESERVED_GOTNO.  Assert htab->use_plts_and_copy_relocs
	instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL.
	Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets.
	Use mips_finish_exec_plt to create non-VxWorks PLT headers.  Set
	DT_MIPS_PLTGOT.
	(_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
	from the indirect symbol to the direct symbol.  Also copy
	has_nonpic_branches for indirect symbols.
	(_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and
	DT_MIPS_RWPLT.
	(_bfd_mips_elf_link_hash_table_create): Initialize the new
	mips_elf_link_hash_table fields.
	(_bfd_mips_vxworks_link_hash_table_create): Set
	use_plts_and_copy_relocs to TRUE.  Use TRUE rather than 1
	when setting is_vxworks.
	(_bfd_mips_elf_use_plts_and_copy_relocs): New function.
	(_bfd_mips_elf_final_link): Call mips_elf_create_la25_stub for
	each la25_stub.
	(_bfd_mips_elf_merge_private_bfd_data): Treat dynamic objects
	as PIC.  Generalize message about linking PIC and non-PIC.
	(_bfd_mips_elf_plt_sym_val, _bfd_mips_post_process_headers): New
	functions.
	* reloc.c: Update comment near BFD_RELOC_MIPS_JUMP_SLOT.
	* bfd-in2.h: Regenerated.
