Before this patch such a call would allocate a super object on the heap and then load the foo method and call it right away. The super object is only needed to perform the lookup of the method and not needed after that. This patch makes an optimisation to allocate the super object on the C stack and discard it right after use. Changes in code size due to this patch are: bare-arm: +128 minimal: +232 unix x64: +416 unix nanbox: +364 stmhal: +184 esp8266: +340 cc3200: +128 2017-03-23T05:36:08+00:00 Damien George damien.p.george@gmail.com 2017-03-23T05:36:08+00:00 urn:sha1:60656eaea41df16557fbbdb51d9b8fc2cf7662a1 It improves readability of code and reduces the chance to make a mistake. This patch also fixes a bug with nan-boxing builds by rounding up the calculation of the new NSLOTS variable, giving the correct number of slots (being 4) even if mp_obj_t is larger than the native machine size. 2017-03-17T05:39:13+00:00 Damien George damien.p.george@gmail.com 2017-03-17T03:54:53+00:00 urn:sha1:71a3d6ec3bd02c5bd13334537e1bd146bb643bad Instead of caching data that is constant (code_info, const_table and n_state), store just a pointer to the underlying function object from which this data can be derived. This helps reduce stack usage for the case when the mp_code_state_t structure is stored on the stack, as well as heap usage when it's stored on the heap. The downside is that the VM becomes a little more complex because it now needs to derive the data from the underlying function object. But this doesn't impact the performance by much (if at all) because most of the decoding of data is done outside the main opcode loop. Measurements using pystone show that little to no performance is lost. This patch also fixes a nasty bug whereby the bytecode can be reclaimed by the GC during execution. With this patch there is always a pointer to the function object held by the VM during execution, since it's stored in the mp_code_state_t structure. 2017-03-14T23:03:22+00:00 Damien George damien.p.george@gmail.com 2017-03-14T23:03:22+00:00 urn:sha1:8cd4911e636092b25dbb6817e67a008d3faeeda9 2017-03-14T12:05:40+00:00 Damien George damien.p.george@gmail.com 2017-03-14T12:00:53+00:00 urn:sha1:a5a84e1f85e795338d462a32632709d7b297d05c Assertions are used to check expressions that should always be true, and mp_not_implemented is used for code that can be reached. 2017-02-16T07:38:06+00:00 Damien George damien.p.george@gmail.com 2017-01-17T04:30:18+00:00 urn:sha1:30b42dd72d4aa310e8c96ccbaf75150f8649c262 2017-02-16T07:38:06+00:00 Damien George damien.p.george@gmail.com 2017-01-17T04:27:37+00:00 urn:sha1:088740ecc40476fd0796a3ef6a68ee7c677eae64
