suspect-devices/circuitpython/py, branch v1.3.8 CircuitPython - a Python implementation for teaching coding with microcontrollers https://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.3.8 2014-12-28T22:51:24+00:00 py: Add MP_LIKELY(), MP_UNLIKELY() macros to help branch prediction. 2014-12-28T22:51:24+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-28T22:51:06+00:00 urn:sha1:361909e3ca8a44632c918aeed2c3426b970068fc showbc: Print operation mnemonic in BINARY_OP. 2014-12-28T19:43:44+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-28T19:41:58+00:00 urn:sha1:1ee1785bed2dc899d92c15047face797f859f1c9 showbc: Make code object start pointer semi-public. 2014-12-28T19:37:17+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-28T19:34:45+00:00 urn:sha1:df103462dc5dedc066ce1d448cf29aee48d1bf55 This allows to pring either absolute addresses or relative offsets in jumps and code references. vm: Record exception ip only for instructions where exceptions may happen. 2014-12-28T05:37:04+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-28T05:17:43+00:00 urn:sha1:749575097f1b5c738cd43dce6ef0960eee8af7a3 Mirroring ip to a volatile memory variable for each opcode is an expensive operation. For quite a lot of often executed opcodes like stack manipulation or jumps, exceptions cannot actually happen. So, record ip only for opcode where that's possible. py: Allow to properly disable builtin slice operation. 2014-12-27T17:33:30+00:00 Damien George damien.p.george@gmail.com 2014-12-27T17:20:41+00:00 urn:sha1:83204f34067b765293b791563bdd5756bdfc5aa4 This patch makes the MICROPY_PY_BUILTINS_SLICE compile-time option fully disable the builtin slice operation (when set to 0). This includes removing the slice sytanx from the grammar. Now, enabling slice costs 4228 bytes on unix x64, and 1816 bytes on stmhal. py: Allow to properly disable builtin "set" object. 2014-12-27T17:33:30+00:00 Damien George damien.p.george@gmail.com 2014-12-27T17:07:16+00:00 urn:sha1:e37dcaafb43c1246ab55d79ebb8889a61f280533 This patch makes MICROPY_PY_BUILTINS_SET compile-time option fully disable the builtin set object (when set to 0). This includes removing set constructor/comprehension from the grammar, the compiler and the emitters. Now, enabling set costs 8168 bytes on unix x64, and 3576 bytes on stmhal. py: Move to guarded includes for compile.h and related headers. 2014-12-27T14:12:17+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-25T21:29:19+00:00 urn:sha1:8ab6f9067412d9f73fe88d42d81c0b4c4f1fd20b showbc: Refactor to allow inline instruction printing. 2014-12-27T03:01:21+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2014-12-27T03:00:08+00:00 urn:sha1:343266ea519927a7f1bc0a27f9c8af768d1125f7 py: Make bytes objs work with more str methods; add tests. 2014-12-24T20:28:30+00:00 Damien George damien.p.george@gmail.com 2014-12-24T20:28:30+00:00 urn:sha1:c55a4d82cf03d22933028bd9db4031ef349fdc1f py: Reduce size of VM exception stack element by 1 machine word. 2014-12-22T12:49:57+00:00 Damien George damien.p.george@gmail.com 2014-12-22T12:49:57+00:00 urn:sha1:74eb44c392449b54a3f0dcf268ee7448909f7b07 This optimisation reduces the VM exception stack element (mp_exc_stack_t) by 1 word, by using bit 1 of a pointer to store whether the opcode was a FINALLY or WITH opcode. This optimisation was pending, waiting for maturity of the exception handling code, which has now proven itself. Saves 1 machine word RAM for each exception (4->3 words per exception). Increases stmhal code by 4 bytes, and decreases unix x64 code by 32 bytes.
