It only makes sense when the word size is 32-bits. unix/modtime: Implement ticks_ms(), ticks_us() and ticks_diff(). 2015-10-19T14:48:27+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-10-17T12:53:55+00:00 urn:sha1:8ee153f23429b63878d740168695cde3fb2a1497 All of these functions return positive small int, thus range is 2 bits less than word size (30 bit on 32-bit systems, 62 bit on 64-bit systems). py: Allow configurable object representation, with 2 different options. 2015-04-03T13:11:13+00:00 Damien George damien.p.george@gmail.com 2015-03-29T13:05:46+00:00 urn:sha1:567184e21e9a6a37fd71153a43874dec7a3f5e0c py: Move to guarded includes, everywhere in py/ core. 2015-01-01T20:32:09+00:00 Damien George damien.p.george@gmail.com 2015-01-01T20:27:54+00:00 urn:sha1:51dfcb4bb7613ed164952712d9a5235a7b833cde Addresses issue #1022. Rename machine_(u)int_t to mp_(u)int_t. 2014-07-03T12:25:24+00:00 Damien George damien.p.george@gmail.com 2014-07-03T12:25:24+00:00 urn:sha1:40f3c026823f8951a2fa04e9c7fc93c75bc27bec See discussion in issue #50. py: Fix check of small-int overflow when parsing ints. 2014-05-28T13:51:12+00:00 Damien George damien.p.george@gmail.com 2014-05-28T13:51:12+00:00 urn:sha1:d1e355ea8e2a5a17ee126f5c3d173b2e6f33e460 Also unifies use of SMALL_INT_FITS macro across parser and runtime. Add license header to (almost) all files. 2014-05-03T22:27:38+00:00 Damien George damien.p.george@gmail.com 2014-05-03T22:27:38+00:00 urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28 Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/. py: This time, real proper overflow checking of small int power. 2014-04-04T11:13:51+00:00 Damien George damien.p.george@gmail.com 2014-04-04T11:13:51+00:00 urn:sha1:ecf5b771230ef747773aa54960ebc2a46902a0ed Previous overflow test was inadequate.
