For ports that don't use nan-boxing there should be no change in generate code because the size of the type remains the same (word sized), and in a lot of cases there won't even be a compiler warning if the type remains as mp_uint_t. The reason for this change is to standardise on the use of size_t for variables that count memory (or memory related) sizes/lengths. It helps builds that use nan-boxing. py: Use mp_raise_TypeError/mp_raise_ValueError helpers where possible. 2017-03-28T11:37:26+00:00 Damien George damien.p.george@gmail.com 2017-03-28T11:37:26+00:00 urn:sha1:94c41bb06f6482ece0717c5bd63266b8da063caa Saves 168 bytes on bare-arm. py: Use mp_locals/mp_globals accessor funcs instead of MP_STATE_CTX. 2017-03-24T07:41:11+00:00 Damien George damien.p.george@gmail.com 2017-03-24T07:41:11+00:00 urn:sha1:707f16b05c663ec3bdaf0ab0713e349638acd0fe To improve maintainability of the code. py: Add micropython.schedule() function and associated runtime code. 2017-03-20T04:20:26+00:00 Damien George damien.p.george@gmail.com 2017-02-16T07:05:06+00:00 urn:sha1:6e74d24f30bca3fb70876b1fb9a6b3a59850b83c py: Use mp_obj_get_array where sequence may be a tuple or a list. 2017-03-07T05:48:16+00:00 Krzysztof Blazewicz blazewicz.krzysztof@gmail.com 2017-03-04T11:29:20+00:00 urn:sha1:7e480e8a30e5e293586bd4806f02a481a08648ca py/runtime.c: Remove optimization of '*a,=b', it caused a bug. 2017-03-07T05:48:16+00:00 Krzysztof Blazewicz blazewicz.krzysztof@gmail.com 2017-03-06T07:46:21+00:00 urn:sha1:1215dc47e2eb8ad3d70e3f1aa1a36a98024019a2 *a, = b should always make a copy of b, instead, before this patch if b was a list it would copy only a reference to it. py/runtime: mp_raise_msg(): Accept NULL argument for message. 2017-02-24T14:57:25+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-02-24T14:57:25+00:00 urn:sha1:4b3da603248fd4e273853af9dd57fbb3c61a9e07 In this case, raise an exception without a message. This would allow to shove few code bytes comparing to currently used mp_raise_msg(..., "") pattern. (Actual savings depend on function code alignment used by a particular platform.) py: De-optimise some uses of mp_getiter, so they don't use the C stack. 2017-02-16T08:11:34+00:00 Damien George damien.p.george@gmail.com 2017-02-13T04:44:31+00:00 urn:sha1:e6003f466e6f5b7eddd01740666230b62ab5a872 In these cases the heap is anyway used to create a new object so no real need to use the C stack for iterating. It saves a few bytes of code size.
