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.

284a130902 or1k: Support large plt_relocs when generating plt entries
The current PLT generation code will generate invalid code when the PLT
relocation offset exceeds 64k.  This fixes the issue by detecting large
plt_reloc offsets and generare code sequences to create larger plt
relocations.

The "large" plt code needs 2 extra instructions to create 32-bit offsets.

c8e98e3692 or1k: Add the l.adrp insn and supporting relocations
This patch adds the new instruction and relocation as per proposal:
   https://openrisc.io/proposals/ladrp

This is to be added to the spec in an upcoming revision.  The new instruction
l.adrp loads the page offset of the current instruction offset by
a 21-bit immediate shifted left 13-bits.  This is meant to be used with
a 13-bit lower bit page offset.  This allows us to free up the got
register r16.

  l.adrp  r3, foo
  l.ori   r4, r3, po(foo)
  l.lbz   r5, po(foo)(r3)
  l.sb    po(foo)(r3), r6

The relocations we add are:

 - BFD_RELOC_OR1K_PLTA26	For PLT jump relocation with PLT entry
   asm: plta()			implemented using l.ardp, meaning
				no need for r16 (the GOT reg)

 - BFD_RELOC_OR1K_GOT_PG21	Upper 21-bit Page offset got address
   asm: got()
 - BFD_RELOC_OR1K_TLS_GD_PG21	Upper 21-bit Page offset with TLS General
   asm: tlsgd()			Dynamic calculation
 - BFD_RELOC_OR1K_TLS_LDM_PG21	Upper 21-bit Page offset with TLS local
   asm: tlsldm()		dynamic calculation
 - BFD_RELOC_OR1K_TLS_IE_PG21	Upper 21-bit Page offset with TLS Initial
   asm: gottp() 		Executable calculation
 - BFD_RELOC_OR1K_PCREL_PG21	Default relocation for disp21 (l.adrp
				instructions)

 - BFD_RELOC_OR1K_LO13		low 13-bit page offset relocation
   asm: po()			i.e. mem loads, addi etc
 - BFD_RELOC_OR1K_SLO13		low 13-bit page offset relocation
   asm: po()			i.e. mem stores, with split immediate
 - BFD_RELOC_OR1K_GOT_LO13,	low 13-bit page offset with GOT calcs
   asm: gotpo()
 - BFD_RELOC_OR1K_TLS_GD_LO13	Lower 13-bit offset with TLS GD calcs
   asm: tlsgdpo()
 - BFD_RELOC_OR1K_TLS_LDM_LO13	Lower 13-bit offset with TLS LD calcs
   asm: tlsldmpo()
 - BFD_RELOC_OR1K_TLS_IE_LO13	Lower 13-bit offset with TLS IE calcs
   asm: gottppo()
