09a0c64bce py: Improve __bool__ and __len__ dispatch; add slots for them. 2014-01-30 10:05:33 +00:00
Paul Sokolovsky
c1d9bbc345 Implement __bool__ and __len__ via unary_op virtual method for all types. 
__bool__() and __len__() are just the same as __neg__() or __invert__(),
and require efficient dispatching implementation (not requiring search/lookup).
type->unary_op() is just the right choice for this short of adding
standalone virtual method(s) to already big mp_obj_type_t structure.

d0691ccaec py: Simplify fastn in VM; reduce size of unique code struct. 
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.

08d075592f py: Fix bug with LOAD_METHOD; fix int->machine_int_t for small int. 
LOAD_METHOD bug was: emitbc did not correctly calculate the amount of
stack usage for a LOAD_METHOD operation.

small int bug was: int was being used to pass small ints, when it should
have been machine_int_t.

d720ab5236 Implement modules as singletons Python semantics. 
In Python, importing module several times returns same underlying module
object. This also fixes import statement handling for builtin modules.

There're still issues:
1. CPython exposes set of loaded modules as sys.modules, we may want to
do that either.
2. Builtin modules are implicitly imported, which is not really correct.
We should separate registering a (builtin) module and importing a module.
CPython keeps builtin module names in sys.builtin_module_names .
