* py: Add simple way of looking up constants in compiler.Damien George2014-04-10
| | | | | | | | | | | | Working towards trying to support compile-time constants (see discussion in issue #227), this patch allows the compiler to look inside arbitrary uPy objects at compile time. The objects to search are given by the macro MICROPY_EXTRA_CONSTANTS (so they must be constant/ROM objects), and the constant folding occures on forms base.attr (both base and attr must be id's). It works, but it breaks strict CPython compatibility, since the lookup will succeed even without importing the namespace.

* py: Simplify stack get/set to become stack adjust in emitters.Damien George2014-04-10
| | | | Can do this now that the stack size calculation is improved.
* py, compiler: Improve stack depth counting.Damien George2014-04-10
| | | | Much less of a hack now. Hopefully it's correct!

* py: Check explicitly for memory allocation failure in parser.Damien George2014-04-10
| | | | | | Previously, a failed malloc/realloc would throw an exception, which was not caught. I think it's better to keep the parser free from NLR (exception throwing), hence this patch.
* Make lexerunix not allocate RAM for the entire script.Damien George2014-04-10
| | | | Now reads in small chunks at a time.
* py: Add emergency exception object for when heap allocation fails.Damien George2014-04-10

* py: Make labels unsigned ints (converted from int).Damien George2014-04-10
| | | | | Labels should never be negative, and this modified type signature reflects that.

| * py: Start implementing "struct" module.Paul Sokolovsky2014-04-10
| | | | | | | | | | | | | | | | | | Only calcsize() and unpack() functions provided so far, for little-endian byte order. Format strings don't support repition spec (like "2b3i"). Unfortunately, dealing with all the various binary type sizes and alignments will lead to quite a bloated "binary" helper functions - if optimizing for speed. Need to think if using dynamic parametrized algos makes more sense.
| * makeqstrdata.py: Add support for conditionally defined qstrs.Paul Sokolovsky2014-04-10
| | | | | | | | Syntax is usual C #if*/#endif, but each qstr must be wrapped individually.

| | | | | | | | | | | | | | | mp_obj_is_integer should be used to check if an object is of integral type. It returns true for bool, small int and long int.

* | py: Make it so that printing a small int does not allocate heap memory.Damien George2014-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With the implementation of proper string formatting, code to print a small int was delegated to mpz_as_str_inpl (after first converting the small int to an mpz using stack memory). But mpz_as_str_inpl allocates heap memory to do the conversion, so small ints needed heap memory just to be printed. This fix has a separate function to print small ints, which does not allocate heap, and allocates less stack. String formatting, printf and pfenv are now large beasts, with some semi-duplicated code.

| | | | | | | | | | | | | | | | | | | | | These two are apprerently the most concise and efficient way to convert int to/from bytes in Python. The alternatives are struct and array modules, but methods using them are more verbose in Python code and less efficient in memory/cycles.

| | | | | | | | | | This makes the runtime and object APIs more consistent. mp_store_subscr functionality now moved into objects (ie list and dict store_item).
