      Remove mp_obj_type_t.methods entry and use .locals_dict instead. · 9b196cdd
      Damien George authored
      Originally, .methods was used for methods in a ROM class, and
      locals_dict for methods in a user-created class.  That distinction is
      unnecessary, and we can use locals_dict for ROM classes now that we have
      ROMable maps.
      This removes an entry in the bloated mp_obj_type_t struct, saving a word
      for each ROM object and each RAM object.  ROM objects that have a
      methods table (now a locals_dict) need an extra word in total (removed
      the methods pointer (1 word), no longer need the sentinel (2 words), but
      now need an mp_obj_dict_t wrapper (4 words)).  But RAM objects save a
      word because they never used the methods entry.
      Overall the ROM usage is down by a few hundred bytes, and RAM usage is
      down 1 word per user-defined type/class.
      There is less code (no need to check 2 tables), and now consistent with
      the way ROM modules have their tables initialised.
      Efficiency is very close to equivaluent.

      Implement proper exception type hierarchy. · c5966128
      Damien George authored
      Each built-in exception is now a type, with base type BaseException.
      C exceptions are created by passing a pointer to the exception type to
      make an instance of.  When raising an exception from the VM, an
      instance is created automatically if an exception type is raised (as
      opposed to an exception instance).
      Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.
      Handling of parse error changed to match new exceptions.
      mp_const_type renamed to mp_type_type for consistency.

      Change mp_obj_type_t.name from const char * to qstr. · a71c83a1
      Damien George authored
      Ultimately all static strings should be qstr.  This entry in the type
      structure is only used for printing error messages (to tell the type of
      the bad argument), and printing objects that don't supply a .print method.

      Improve method lookup in mp_obj_class_lookup. · f49ba1bd

      Now searches both locals_dict and methods.  Partly addresses Issue #145.

      Now working for class-defined methods: __getitem__, __setitem__,
      __add__, __sub__.  Easy to add others.

      Make VM stack grow upwards, and so no reversed args arrays. · 20006dbb
      Damien George authored
      Change state layout in VM so the stack starts at state[0] and grows
      upwards.  Locals are at the top end of the state and number downwards.
      This cleans up a lot of the interface connecting the VM to C: now all
      functions that take an array of Micro Python objects are in order (ie no
      longer in reverse).
      Also clean up C API with keyword arguments (call_n and call_n_kw
      replaced with single call method that takes keyword arguments).  And now
      make_new takes keyword arguments.
      emitnative.c has not yet been changed to comply with the new order of
      stack layout.

      Change object representation from 1 big union to individual structs. · d99b0528
      Damien authored
      A big change.  Micro Python objects are allocated as individual structs
      with the first element being a pointer to the type information (which
      is itself an object).  This scheme follows CPython.  Much more flexible,
      not necessarily slower, uses same heap memory, and can allocate objects
      Also change name prefix, from py_ to mp_ (mp for Micro Python).
