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.
