- config/arc/arc-protos.h (compact_memory_operand_p): Declare.
- config/arc/arc.c (arc_output_commutative_cond_exec): Consider bmaskn instruction. (arc_dwarf_register_span): Remove enum keyword. (compact_memory_operand_p): New function.
- config/arc/arc.h (reg_class): Add code density register classes. (REG_CLASS_NAMES): Likewise. (REG_CLASS_CONTENTS): Likewise.
- config/arc/arc.md (*movqi_insn): Add code density instructions. (*movhi_insn, *movsi_insn, *movsf_insn): Likewise. (*extendhisi2_i, andsi3_i, cmpsi_cc_insn_mixed): Likewise. (*cmpsi_cc_c_insn, *movsi_ne): Likewise.
- config/arc/constraints.md (C2p, Uts, Cm1, Cm3, Ucd): New constraints. (h, Rcd, Rsd, Rzd): New register constraints. (T): Use compact_memory_operand_p function.
- config/arc/predicates.md (compact_load_memory_operand): Remove.
