+ * configure.in (crisv32): Recognize. AC_DEFINE_UNQUOTED
+ DEFAULT_CRIS_ARCH. Handle crisv32-*-linux-gnu* like

+ (md_pseudo_table): New pseudo .arch.
+ (err_for_dangerous_mul_placement): Initialize according to
+ DEFAULT_CRIS_ARCH.

+ (BRANCH_BF, BRANCH_BB, BRANCH_WF, BRANCH_WB): Don't undef after
+ use in md_cris_relax_table.
+ (md_cris_relax_table): Add entries for STATE_COND_BRANCH_V32,
+ STATE_COND_BRANCH_COMMON, STATE_ABS_BRANCH_V32, STATE_LAPC.
+ Update and improve head comment.
+ (OPTION_PIC): Define in terms of previous option, OPTION_US.
+ (OPTION_MULBUG_ABORT_ON, OPTION_MULBUG_ABORT_OFF): Similar.

+ macros.
+ (md_long_jump_size): Initialize in terms of DEFAULT_CRIS_ARCH.
+ (HANDLE_RELAXABLE): New macro.
+ (md_estimate_size_before_relax): Use HANDLE_RELAXABLE for common
+ cases. Check for weak symbols and assume not relaxable. Handle
+ STATE_COND_BRANCH_V32, STATE_COND_BRANCH_COMMON,
+ STATE_ABS_BRANCH_V32, STATE_LAPC. Use new variable symbolP, not
+ fragP->fr_symbol.
+ (md_convert_frag): Handle STATE_COND_BRANCH_V32,
+ STATE_COND_BRANCH_COMMON, STATE_ABS_BRANCH_V32, STATE_LAPC.
+ (cris_create_short_jump): Adjust for CRISv32.
+ (md_create_long_jump): Ditto. Emit error for common_v10_v32.
+ (md_begin): Define symbols "..asm.arch.cris.v32",
+ "..asm.arch.cris.v10", "..asm.arch.cris.common_v10_v32" and
+ "..asm.arch.cris.any_v0_v10". Use cris_insn_ver_valid_for_arch
+ when entering opcode table entry points.
+ (md_assemble): Adjust branch handling for CRISv32. Handle LAPC
+ relaxation. In fix_new_exp call for main insn, pass 1 for pcrel
+ parameter for 8, 16 and 32-bit pc-relative insns and LAPC.
+ (cris_process_instruction): Initialize out_insnp->insn_type to
+ CRIS_INSN_NONE, not CRIS_INSN_NORMAL.

+ cases.
+ <case 'm'>: Check that modified_char == '.'.
+ <invalid operands>: Consume the rest of the line.
+ When operands don't match, skip over subsequent insns with
+ non-matching version specifier but same mnemonic.
+ <immediate constant, case SIZE_SPEC_REG>: Immediate operands for
+ special registers in CRISv32 are always 32 bit long.
+ <immediate constant, case SIZE_FIELD_SIGNED, SIZE_FIELD_UNSIGNED>:
+ New cases.
+ (get_gen_reg): Only recognize "PC" when followed by "+]" for v32
+ and compatible. Recognize "ACR" for v32, unless followed by "+".
+ (get_spec_reg): Consider cris_arch when looking up register.
+ (get_autoinc_prefix_or_indir_op): Don't recognize assignment for
+ v32 or compatible.
+ (get_3op_or_dip_prefix_op): Check for ']' after seeing '[rN+'.
+ (cris_get_expression): Restore input_line_pointer if failing "early".
+ (get_flags): Consider cris_arch and recognize flags accordingly.
+ (branch_disp): Adjust for CRISv32.
+ (gen_cond_branch_32): Similar. Emit error for common_v10_v32.
+ (cris_number_to_imm): Use as_bad_where, not as_bad. Remove
+ related FIXME. Don't insist on BFD_RELOC_32_PCREL fixup to be
+ resolved. Don't enter zeros in object file for
+ BFD_RELOC_32_PCREL.
+ <case BFD_RELOC_CRIS_LAPCQ_OFFSET, BFD_RELOC_CRIS_SIGNED_16>
