It also reduces code size quite a bit for nan-boxing builds. 2017-07-31T08:35:40+00:00 Alexander Steffen devel.20.webmeister@spamgourmet.com 2017-06-30T07:22:17+00:00 urn:sha1:55f33240f3d7051d4213629e92437a36f1fac50e There were several different spellings of MicroPython present in comments, when there should be only one. 2017-07-18T01:57:39+00:00 Alexander Steffen devel.20.webmeister@spamgourmet.com 2017-06-29T21:14:58+00:00 urn:sha1:299bc625864b9e624ed599c94a5f95870516139a The code conventions suggest using header guards, but do not define how those should look like and instead point to existing files. However, not all existing files follow the same scheme, sometimes omitting header guards altogether, sometimes using non-standard names, making it easy to accidentally pick a "wrong" example. This commit ensures that all header files of the MicroPython project (that were not simply copied from somewhere else) follow the same pattern, that was already present in the majority of files, especially in the py folder. The rules are as follows. Naming convention: * start with the words MICROPY_INCLUDED * contain the full path to the file * replace special characters with _ In addition, there are no empty lines before #ifndef, between #ifndef and one empty line before #endif. #endif is followed by a comment containing the name of the guard macro. py/grammar.h cannot use header guards by design, since it has to be included multiple times in a single C file. Several other files also do not need header guards as they are only used internally and guaranteed to be included only once: * MICROPY_MPHALPORT_H * mpconfigboard.h * mpconfigport.h * mpthreadport.h * pin_defs_*.h * qstrdefs*.h 2017-04-04T06:45:49+00:00 Damien George damien.p.george@gmail.com 2017-04-04T06:45:49+00:00 urn:sha1:fc245d1ca4367f9876ac32c7e08e169da7db79b9 This reduces code duplication and allows to make mp_classify_fp_as_int static, which reduces code size. 2017-02-02T19:23:10+00:00 Nicko van Someren nicko@nicko.org 2017-02-01T23:41:22+00:00 urn:sha1:df0117c8ae213a0652c3b19a969edc7fd994eeab Updated modbuiltin.c to add conditional support for 3-arg calls to pow() using MICROPY_PY_BUILTINS_POW3 config parameter. Added support in objint_mpz.c for for optimised implementation. 2017-01-21T17:14:18+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-01-21T17:14:18+00:00 urn:sha1:bec7bfb29d76f995dbf223c20f5d04ae1e33cee6 If result guaranteedly fits in a small int, it is handled in objint.c. Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should be implemented by individual objint_*.c, similar to mp_obj_int_to_bytes_impl(). 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.
