sim: eBPF simulator
This patch introduces the basics of an instruction-simulator for eBPF. The simulator is based on CGEN. gdb/ChangeLog: 2020-08-04 Jose E. Marchesi <jose.marchesi@oracle.com> * configure.tgt: Set gdb_sim for bpf-*-* targets. sim/ChangeLog: 2020-08-04 Jose E. Marchesi <jose.marchesi@oracle.com> David Faust <david.faust@oracle.com> * configure.tgt (sim_arch): Add entry for bpf-*-*. * configure: Regenerate. * MAINTAINERS: Add maintainer for the BPF simulator. * bpf/Makefile.in: New file. * bpf/bpf-helpers.c: Likewise. * bpf/bpf-helpers.def: Likewise. * bpf/bpf-helpers.h: Likewise. * bpf/bpf-sim.h: Likewise. * bpf/bpf.c: Likewise. * bpf/config.in: Likewise. * bpf/configure.ac: Likewise. * bpf/decode.h: Likewise. * bpf/eng.h: Likewise. * bpf/mloop.in: Likewise. * bpf/sim-if.c: Likewise. * bpf/sim-main.h: Likewise. * bpf/traps.c: Likewise. * bpf/configure: Generate. * bpf/aclocal.m4: Likewise. sim/testsuite/ChangeLog: 2020-08-04 David Faust <david.faust@oracle.com> Jose E.
