PowerPC add initial -mfuture instruction support
This patch adds initial 64-bit insn assembler/disassembler support.
The only instruction added is "pnop" along with the automatic aligning
of prefix instruction so they do not cross 64-byte boundaries.
include/
* dis-asm.h (WIDE_OUTPUT): Define.
* opcode/ppc.h (prefix_opcodes, prefix_num_opcodes): Declare.
(PPC_OPCODE_POWERXX, PPC_GET_PREFIX, PPC_GET_SUFFIX),
(PPC_PREFIX_P, PPC_PREFIX_SEG): Define.
opcodes/
* ppc-dis.c (ppc_opts): Add "future" entry.
(PREFIX_OPCD_SEGS): Define.
(prefix_opcd_indices): New array.
(disassemble_init_powerpc): Initialize prefix_opcd_indices.
(lookup_prefix): New function.
(print_insn_powerpc): Handle 64-bit prefix instructions.
* ppc-opc.c (PREFIX_OP, PREFIX_FORM, SUFFIX_MASK, PREFIX_MASK),
(PMRR, POWERXX): Define.
(prefix_opcodes): New instruction table.
(prefix_num_opcodes): New constant.
binutils/
* objdump.c (disassemble_bytes): Set WIDE_OUTPUT in flags.
gas/
* config/tc-ppc.c (ppc_setup_opcodes): Handle prefix_opcodes.
(struct insn_label_list): New.
(insn_labels, free_insn_labels): New variables.
(ppc_record_label, ppc_clear_labels, ppc_start_line_hook): New funcs.
(ppc_frob_label, ppc_new_dot_label): Move functions earlier in file
and call ppc_record_label.
(md_assemble): Handle 64-bit prefix instructions. Align labels
that are on the same line as a prefix instruction.
* config/tc-ppc.h (tc_frob_label, ppc_frob_label): Move to
later in the file.
(md_start_line_hook): Define.
(ppc_start_line_hook): Declare.
* testsuite/gas/ppc/prefix-align.d,
* testsuite/gas/ppc/prefix-align.s: New test.
* testsuite/gas/ppc/ppc.exp: Run new test.
