Flesh out ExecContext serialize/unserialize (including RegFile).
Add support for serializing enums. arch/alpha/isa_traits.hh: Add serialize/unserialize functions for RegFile (defined in new isa_traits.cc). cpu/exec_context.cc: Flesh out serialize/unserialize. sim/serialize.hh: Add {UN}SERIALIZE_ENUM(). --HG-- extra : convert_revision : 9e30c7e7b3b290dc8ea0888ba3636fc93ee89052
