bpf: gas,include,opcode: add suppor for instructions BSWAP{16,32,64}
This patch adds support for the BPF V4 ISA byte swap instructions to
opcodes, assembler and disassembler.
Tested in bpf-unknown-none.
include/ChangeLog:
2023-07-24 Jose E. Marchesi <jose.marchesi@oracle.com>
* opcode/bpf.h (BPF_IMM32_BSWAP16): Define.
(BPF_IMM32_BSWAP32): Likewise.
(BPF_IMM32_BSWAP64): Likewise.
(enum bpf_insn_id): New entries BPF_INSN_BSWAP{16,32,64}.
opcodes/ChangeLog:
2023-07-24 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf-opc.c (bpf_opcodes): Add entries for the BSWAP*
instructions.
gas/ChangeLog:

* doc/c-bpf.texi (BPF Instructions): Document BSWAP* instructions.
* testsuite/gas/bpf/alu.s: Test BSWAP{16,32,64} instructions.
* testsuite/gas/bpf/alu.d: Likewise.
* testsuite/gas/bpf/alu-be.d: Likewise.
* testsuite/gas/bpf/alu-pseudoc.s: Likewise.
* testsuite/gas/bpf/alu-pseudoc.d: Likewise.
* testsuite/gas/bpf/alu-be-pseudoc.d: Likewise.
