cpu,opcodes,gas: fix explicit arguments to eBPF ldabs instructions
This patch fixes the eBPF CPU description in order to reflect the
right explicit arguments passed to the ldabs{b,h,w,dw} instructions,
updates the corresponding GAS tests, and updates the BPF section of
the GAS manual.
cpu/ChangeLog:
2019-07-15 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf.cpu (dlabs): New pmacro.
(dlind): Likewise.
opcodes/ChangeLog:
2019-07-15 Jose E. Marchesi <jose.marchesi@oracle.com>
* bpf-desc.c: Regenerate.
* bpf-opc.c: Likewise.
* bpf-opc.h: Likewise.
gas/ChangeLog:
2019-07-15 Jose E. Marchesi <jose.marchesi@oracle.com>
* testsuite/gas/bpf/mem.s: ldabs instructions do not take a `src'
register as an argument.
* testsuite/gas/bpf/mem.d: Updated accordingly.
* testsuite/gas/bpf/mem-be.d: Likewise.
* doc/c-bpf.texi (BPF Opcodes): Update to reflect the correct
explicit arguments to ldabs and ldind instructions.
