bpf: xBPF SDIV, SMOD instructions
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.
gas/
* 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.
opcodes/
* bpf-desc.c: Regenerate.
* bpf-desc.h: Likewise.
* bpf-opc.c: Likewise.
* bpf-opc.h: Likewise.
