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.

Add gas and opcodes support for two xBPF-exclusive ALU operations:
SDIV (signed division) and SMOD (signed modulo), and add tests for
them in gas.
cpu/
* bpf.cpu (insn-op-code-alu): Add SDIV and SMOD.
(define-alu-insn-bin, daib): Take ISAs as an argument.
(define-alu-instructions): Update calls to daib pmacro with
ISAs; add sdiv and smod.

* testsuite/gas/bpf/alu-xbpf.d: New file.
* testsuite/gas/bpf/alu-xbpf.s: Likewise.
* testsuite/gas/bpf/alu32-xbpf.d: Likewise.
* testsuite/gas/bpf/alu32-xbpf.d: Likewise.
* testuiste/gas/bpf/bpf.exp: Run new tests.

This patch adds support for xBPF, another ISA targetting the BPF
virtual architecture. For now, the primary difference between eBPF
and xBPF is that xBPF supports indirect calls through the
'call %reg' form of the call instruction.
bfd/
* archures.c (bfd_mach_xbpf): Define.
* bfd-in2.h: Regenerate.
* cpu-bpf.c (bfd_xbpf_arch) New.
(bfd_bpf_arch) Update next in list field to point to xbpf arch.
cpu/

(define-xbpf-isa) New pmacro.
(all-isas) Add xbpfle,xbpfbe.
(endian-isas): New pmacro.
(mach xbpf): New.
(model xbpf-def): Likewise.
(h-gpr): Add xbpf mach.
(f-dstle, f-srcle, dstle, srcle): Add xbpfle isa.
(f-dstbe, f-srcbe, dstbe, srcbe): Add xbpfbe isa.
(define-alu-insn-un): Use new endian-isas pmacro.
