2020-08-26bpf: add xBPF ISADavid Faust1-1/+21
This patch adds support for xBPF, another ISA targetting the BPF virtual architecture. For now, the primary difference between eBPF and xBPF is that xBPF supports indirect calls through the 'call %reg' form of the call instruction. bfd/ * archures.c (bfd_mach_xbpf): Define. * bfd-in2.h: Regenerate. * cpu-bpf.c (bfd_xbpf_arch) New. (bfd_bpf_arch) Update next in list field to point to xbpf arch. cpu/ * bpf.cpu (arch bpf): Add xbpf mach and isas. (define-xbpf-isa) New pmacro. (all-isas) Add xbpfle,xbpfbe. (endian-isas): New pmacro. (mach xbpf): New. (model xbpf-def): Likewise. (h-gpr): Add xbpf mach. (f-dstle, f-srcle, dstle, srcle): Add xbpfle isa. (f-dstbe, f-srcbe, dstbe, srcbe): Add xbpfbe isa.
