opcodes: add support for eBPF
This patch adds support for the Linux kernel eBPF architecture to the
opcodes. The port is based on CGEN.
opcodes/ChangeLog:
2019-05-23 Jose E. Marchesi <jose.marchesi@oracle.com>
* configure.ac (SHARED_DEPENDENCIES): Add case for bfd_bpf_arch.
* configure: Regenerated.
* Makefile.am: Add rules for the files generated from cpu/bpf.cpu
and cpu/bpf.opc.
(HFILES): Add bpf-desc.h and bpf-opc.h.
(TARGET_LIBOPCODES_CFILES): Add bpf-asm.c, bpf-desc.c, bpf-dis.c,
bpf-ibld.c and bpf-opc.c.
(BPF_DEPS): Define.
* Makefile.in: Regenerated.
* disassemble.c (ARCH_bpf): Define.
(disassembler): Add case for bfd_arch_bpf.
(disassemble_init_for_target): Likewise.
(enum epbf_isa_attr): Define.
* disassemble.h: extern print_insn_bpf.
* bpf-asm.c: Generated.
* bpf-opc.h: Likewise.
* bpf-opc.c: Likewise.
* bpf-ibld.c: Likewise.
* bpf-dis.c: Likewise.
* bpf-desc.h: Likewise.
* bpf-desc.c: Likewise.
