2019-07-15	cpu,opcodes,gas: fix explicit arguments to eBPF ldabs instructions	Jose E. Marchesi	1	-4/+3
	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.
2019-05-23	opcodes: add support for eBPF	Jose E. Marchesi	1	-0/+151
	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.
