cpu,opcodes,gas: fix neg and neg32 instructions in BPF
This patch fixes the neg/neg32 BPF instructions, which have K (=0)
instead of X (=1) in their header source bit, despite operating on
registes.
cpu/ChangeLog:
2020-01-30 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf.cpu (define-alu-insn-un): The unary BPF instructions
(neg and neg32) use OP_SRC_K even if they operate only in
registers.
opcodes/ChangeLog:
2020-01-30 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf-opc.c: Regenerate.
gas/ChangeLog:
2020-01-30 Jose E. Marchesi <jose.marchesi@oracle.com>
* testsuite/gas/bpf/alu.d: Update expected opcode for `neg'.
* testsuite/gas/bpf/alu-be.d: Likewise.
* testsuite/gas/bpf/alu32.d: Likewise for `neg32'.
* testsuite/gas/bpf/alu32-be.d: Likewise.
