      py: Put n_state for bytecode in the bytecode prelude. · bee17b00
      Damien George authored
      Rationale: setting up the stack (state for locals and exceptions) is
      really part of the "code", it's the prelude of the function.  For
      example, native code adjusts the stack pointer on entry to the function.
      Native code doesn't need to know n_state for any other reason.  So
      putting the state size in the bytecode prelude is sensible.
      
      It reduced ROM usage on STM by about 30 bytes :)  And makes it easier to
      pass information about the bytecode between functions.

      py: VM never throws an exception, instead returns a status and value. · c8f78bc2
      Damien George authored
      Addresses issue #290, and hopefully sets up things to allow generators
      throwing exceptions, etc.

      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.

      py: Simplify fastn in VM; reduce size of unique code struct. · d0691cca
      Damien George authored
      We still have FAST_[0,1,2] byte codes, but they now just access the
      fastn array (before they had special local variables).  It's now
      simpler, a bit faster, and uses a bit less stack space (on STM at least,
      which is most important).
      
      The only reason now to keep FAST_[0,1,2] byte codes is for compressed
      byte code size.

      Add source file name and line number to error messages. · 08335004
      Damien George authored
      Byte code has a map from byte-code offset to source-code line number,
      used to give better error messages.

      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.
