fd67aa1129 Update year range in copyright notice of binutils files
Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:

1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
   author I haven't committed, 'Kalray SA.', to cover gas testsuite
   files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

d605374748 bfd: microblaze: Add 32_NONE reloc type
This patch adds the R_MICROBLAZE_32_NONE relocation type.
This is a 32-bit reloc that stores the 32-bit pc relative
value in two words (with an imm instruction).

Add test case to gas test suite.

6bbf249557 opcodes: microblaze: Add new bit-field instructions
This patches adds new bsefi and bsifi instructions.
BSEFI- The instruction shall extract a bit field from a
register and place it right-adjusted in the destination register.
The other bits in the destination register shall be set to zero.
BSIFI- The instruction shall insert a right-adjusted bit field
from a register at another position in the destination register.
The rest of the bits in the destination register shall be unchanged.

Further documentation of these instructions can be found here:
https://docs.xilinx.com/v/u/en-US/ug984-vivado-microblaze-ref

This patch has been tested for years of AMD Xilinx Yocto
releases as part of the following patch set:

d87bef3a7b Update year range in copyright notice of binutils files
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.

a2c5833233 Update year range in copyright notice of binutils files
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.

3f0a5f17d7 [MicroBlaze] PIC data text relative
Andrew Sadek <andrew.sadek.se@gmail.com>

A new implemented feature in GCC Microblaze that allows Position
Independent Code to run using Data Text Relative addressing instead
of using Global Offset Table.

Its aim was to make 'PIC' more efficient and flexible as elf size
excess performance overhead were noticed when using GOT due to the
indirect addressing.

include/ChangeLog:
	* bfdlink.h (Add flag): Add new flag @ 'bfd_link_info' struct.
	* elf/microblaze.h (Add 3 new relocations):
	R_MICROBLAZE_TEXTPCREL_64, R_MICROBLAZE_TEXTREL_64
	and R_MICROBLAZE_TEXTREL_32_LO for relax function.
bfd/ChangeLog:
	* bfd/reloc.c (2 new BFD relocations):
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL &
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL
	* bfd/bfd-in2.h: Regenerate
	* bfd/libbfd.h: Regenerate
	* bfd/elf32-microblaze.c (Handle new relocs): define 'HOWTO' of 3
	new relocs and handle them in both relocate and relax functions.
	(microblaze_elf_reloc_type_lookup): add mapping between for new
	bfd relocs.
	(microblaze_elf_relocate_section): Handle new relocs in case of
	elf relocation.
	(microblaze_elf_relax_section): Handle new relocs for elf relaxation.
gas/ChangeLog:
	* gas/config/tc-microblaze.c (Handle new relocs directives in
	assembler): Handle new relocs from compiler output.
	(imm_types): add new imm types for data text relative addressing
	TEXT_OFFSET, TEXT_PC_OFFSET
	(md_convert_frag): conversion for BFD_RELOC_MICROBLAZE_64_TEXTPCREL,
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL
	(md_apply_fix): apply fix for BFD_RELOC_MICROBLAZE_64_TEXTPCREL,
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL
	(md_estimate_size_before_relax): estimate size for
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL,
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL
	(tc_gen_reloc): generate relocations for
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL,
	BFD_RELOC_MICROBLAZE_64_TEXTPCREL
ld/ChangeLog:
	* ld/lexsup.c (Add 2 ld options):
	(ld_options): add disable-multiple-abs-defs @ 'ld_options' array
	(parse_args): parse new option and pass flag to 'link_info' struct.
	* ld/ldlex.h (Add enum): add new enum @ 'option_values' enum.
	* ld/ld.texinfo (Add new option): Add description for
	'disable-multiple-abs-defs'
	* ld/main.c: Initialize flags with false @ 'main'. Handle
	disable-multiple-abs-defs @ 'mutiple_definition'.
