* vm: Save current active exception on opening new try block.Paul Sokolovsky2014-03-30
| | | | | | | | | | | Required to reraise correct exceptions in except block, regardless if more try blocks with active exceptions happen in the same except block. P.S. This "automagic reraise" appears to be quite wasteful feature of Python - we need to save pending exception just in case it *might* be reraised. Instead, programmer could explcitly capture exception to a variable using "except ... as var", and reraise that. So, consider disabling argless raise support as an optimization.

* py: Make MP_BC_SETUP_WITH use the bytecode stack for load_method.Damien George2014-03-29
| | | | | | The compiler allocates 7 entries on the stack for a with statement (following CPython, but probably can be reduced). This is enough for the method load and call in SETUP_WITH.

* | vm: Make sure that exception triple is <type, instance, traceback>.Paul Sokolovsky2014-03-29
| | | | | | | | | | | | | | This reduntant triple is one of the ugliest parts of Python, which they chickened out to fix in Python3. We really should consider passing just as single exception instance (without breaking Python-level APIs of course), but until we do, let's follow CPython layout.

* py: Put n_state for bytecode in the bytecode prelude.Damien George2014-03-27
| | | | | | | | | | | 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.

* / Remove mp_obj_type_t.methods entry and use .locals_dict instead.Damien George2014-03-26
|/ | | | | | | | | | | | | | | | | | | | | | 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.
