suspect-devices/circuitpython/py/objdict.c, branch v1.9.3 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.9.3 2017-10-04T01:37:50+00:00 all: Remove inclusion of internal py header files. 2017-10-04T01:37:50+00:00 Damien George damien.p.george@gmail.com 2017-10-04T01:37:50+00:00 urn:sha1:a3dc1b1957d2c96d7c60c2c629c95077b03488a1 Header files that are considered internal to the py core and should not normally be included directly are: py/nlr.h - internal nlr configuration and declarations py/bc0.h - contains bytecode macro definitions py/runtime0.h - contains basic runtime enums Instead, the top-level header files to include are one of: py/obj.h - includes runtime0.h and defines everything to use the mp_obj_t type py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h, and defines everything to use the general runtime support functions Additional, specific headers (eg py/objlist.h) can be included if needed. all: Convert mp_uint_t to mp_unary_op_t/mp_binary_op_t where appropriate 2017-08-29T03:16:30+00:00 Damien George damien.p.george@gmail.com 2017-08-29T03:04:01+00:00 urn:sha1:58321dd9854d71a96e5db2d361e0efc05d9de8cf The unary-op/binary-op enums are already defined, and there are no arithmetic tricks used with these types, so it makes sense to use the correct enum type for arguments that take these values. It also reduces code size quite a bit for nan-boxing builds. py/modsys: Initial implementation of sys.getsizeof(). 2017-08-11T06:43:07+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-08-11T06:42:39+00:00 urn:sha1:bfc2092dc55d1faab4a6d7e832005afd61d25c3c Implemented as a new MP_UNARY_OP.

So it makes sense to optimise the case of 1 parent type by storing just the type and not a tuple of 1 value (that value being the single parent type). This patch makes such an optimisation. Even though there is a bit more code to handle the two cases (either a single type or a tuple with 2 or more values) it helps reduce overall code size because it eliminates the need to create a static tuple to hold single parents (eg for the built-in exceptions). It also helps reduce RAM usage for user defined types that only derive from a single parent. Changes in code size (in bytes) due to this patch: bare-arm: -16 minimal (x86): -176 unix (x86-64): -320 unix nanbox: -384 stmhal: -64 cc3200: -32 esp8266: -108 py: Shorten a couple of error messages. 2017-03-29T01:36:46+00:00 Damien George damien.p.george@gmail.com 2017-03-29T01:36:46+00:00 urn:sha1:18c059febfd713271155d25a3a28661e8911ef8d 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: 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.
