cpu,opcodes,gas: fix arguments to ldabs and ldind eBPF instructions
The eBPF non-generic load instructions ldind{b,h,w,dw} and
ldabs{b,h,w,dw} do not take an explicit destination register as an
argument. Instead, they put the loaded value in %r0, implicitly.
This patch fixes the CPU BPF description to not expect a 'dst'
argument in these arguments, regenerates the corresponding files in
opcodes, and updates the impacted GAS tests.
Tested in a x86-64 host.
cpu/ChangeLog:
2019-07-14 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf.cpu (dlsi): ldabs and ldind instructions do not take an
explicit 'dst' argument.
opcodes/ChangeLog:
2019-07-14 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf-desc.c: Regenerate.
* bpf-opc.c: Likewise.
gas/ChangeLog:
2019-07-14 Jose E. Marchesi <jose.marchesi@oracle.com>
* testsuite/gas/bpf/mem.s: Do not use explicit arguments for
ldabs and ldind instructions.
* testsuite/gas/bpf/mem.d: Updated accordingly.
* testsuite/gas/bpf/mem-be.d: Likewise.
