CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.8.7 2016-12-21T00:46:27+00:00 2016-12-21T00:46:27+00:00 Damien George damien.p.george@gmail.com 2016-12-21T00:46:27+00:00 urn:sha1:e4af71212550d950269f6991be187f41dcf64eee And also simplify it to remove the check for small int. This can be done because this function is only ever called if the argument is not a small int. 2016-10-21T05:26:01+00:00 Damien George damien.p.george@gmail.com 2016-10-18T00:49:27+00:00 urn:sha1:571e6f26dbd7e0e38441bc402f76d293303063b2 Builtin functions with a fixed number of arguments (0, 1, 2 or 3) are quite common. Before this patch the wrapper for such a function cost 3 machine words. After this patch it only takes 2, which can reduce the code size by quite a bit (and pays off even more, the more functions are added). It also makes function dispatch slightly more efficient in CPU usage, and furthermore reduces stack usage for these cases. On x86 and Thumb archs the dispatch functions are now tail-call optimised by the compiler. The bare-arm port has its code size increase by 76 bytes, but stmhal drops by 904 bytes. Stack usage by these builtin functions is decreased by 48 bytes on Thumb2 archs. 2016-10-21T05:26:01+00:00 Damien George damien.p.george@gmail.com 2016-10-18T00:06:20+00:00 urn:sha1:4ebdb1f2b217410cdc1cee0e0c0da8fceb7627f2 In order to have more fine-grained control over how builtin functions are constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific, with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW. These names now match the MP_DEFINE_CONST_FUN_OBJ macros. 2016-09-21T14:23:16+00:00 Damien George damien.p.george@gmail.com 2016-09-21T00:52:53+00:00 urn:sha1:93c4a6a3f70e389b466fbc7a4f1ad2e1df87c93f One can instead lookup __name__ in the modules dict to get the value. 2016-08-15T00:56:55+00:00 Damien George damien.p.george@gmail.com 2016-08-15T00:56:55+00:00 urn:sha1:41fceae559ff2272a88441dbf531232f173ccbd6 The machine_ptr_t type is long obsolete as the type of mp_obj_t is now defined by the object representation, ie by MICROPY_OBJ_REPR. So just use void* explicitly for the typedef of mp_obj_t. If a port wants to use something different then they should define a new object representation. 2016-06-18T15:44:57+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-06-18T15:19:24+00:00 urn:sha1:07209f8592f15435d6abbccaad5347cea2c7722e It's now used for more than just stream protocol (e.g. pin protocol), so don't use false names. 2016-05-04T09:19:08+00:00 Damien George damien.p.george@gmail.com 2016-05-04T09:19:08+00:00 urn:sha1:eb54e4d065a7cbc26dc4c8dc2812d1cabdcd0c50 2016-04-26T08:51:37+00:00 Damien George damien.p.george@gmail.com 2016-04-26T08:51:37+00:00 urn:sha1:2bddfd492255d03a695a1e7488de3fba80b8e5ab The C standard says that left-shifting a signed value (on the LHS of the operator) is undefined. So we cast to an unsigned integer before the shift. gcc does not issue a warning about this, but clang does. 2016-04-13T14:26:38+00:00 pohmelie multisosnooley@gmail.com 2016-01-27T20:23:11+00:00 urn:sha1:81ebba7e0236163b7594938201bf3a6b802ebfaa They are sugar for marking function as generator, "yield from" and pep492 python "semantically equivalents" respectively. @dpgeorge was the original author of this patch, but @pohmelie made changes to implement `async for` and `async with`. 2016-04-05T19:06:52+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2016-04-05T18:58:03+00:00 urn:sha1:e6a4d4e23c5e3d31436d3cebfabc894d5772c0d8
