suspect-devices/circuitpython/py/runtime0.h, 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 2017-10-11T07:54:34+00:00 py/emitnative: Implement floor-division and modulo for viper emitter. 2017-10-11T07:54:34+00:00 Damien George damien.p.george@gmail.com 2017-10-11T07:54:34+00:00 urn:sha1:a3afa8cfc46913f471d5eb55da4ae22dee92c25f py: Clean up unary and binary enum list to keep groups together. 2017-10-04T23:49:44+00:00 Damien George damien.p.george@gmail.com 2017-10-03T12:34:28+00:00 urn:sha1:0864a6957fe4717c3ec40ceeb373b19614a18434 2 non-bytecode binary ops (NOT_IN and IN_NOT) are moved out of the bytecode group, so this change will change the bytecode format. py: Clarify which mp_unary_op_t's may appear in the bytecode. 2017-09-25T23:35:19+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-25T23:35:19+00:00 urn:sha1:9d836fedbdb1d28bdfc4ba475bbdfc1adb3f007a Not all can, so we don't need to reserve bytecodes for them, and can use free slots for something else later. py/runtime0: Add comments about unary/binary-op enums used in bytecode. 2017-09-22T01:54:08+00:00 Damien George damien.p.george@gmail.com 2017-09-22T01:54:08+00:00 urn:sha1:8edc2e4b141ffad74754686fbdc66e033ff24f34 py/modbuiltins: Implement abs() by dispatching to MP_UNARY_OP_ABS. 2017-09-17T21:06:43+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-17T21:06:43+00:00 urn:sha1:9dce823cfd0a9991350184f08a1373f3887134f4 This allows user classes to implement __abs__ special method, and saves code size (104 bytes for x86_64), even though during refactor, an issue was fixed and few optimizations were made: * abs() of minimum (negative) small int value is calculated properly. * objint_longlong and objint_mpz avoid allocating new object is the argument is already non-negative. py/runtime: Implement dispatch for "reverse op" special methods. 2017-09-10T14:05:57+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-10T14:05:20+00:00 urn:sha1:eb84a830df62813f5af7f0144fc77444bf18f3a8 If, for class X, X.__add__(Y) doesn't exist (or returns NotImplemented), try Y.__radd__(X) instead. This patch could be simpler, but requires undoing operand swap and operation switch to get non-confusing error message in case __radd__ doesn't exist. py/runtime0.h: Put inplace arith ops in front of normal operations. 2017-09-07T21:10:10+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-07T21:10:10+00:00 urn:sha1:b8ee7ab5b988f424e34e778fe3a679710d675efa This is to allow to place reverse ops immediately after normal ops, so they can be tested as one range (which is optimization for reverse ops introduction in the next patch). py/runtime0.h: Regroup operations a bit. 2017-09-07T10:37:33+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-07T10:37:33+00:00 urn:sha1:c460f6f15af681860f7606761da7579c9945761b Originally, there were grouped in blocks of 5, to make it easier e.g. to assess and numeric code of each. But now it makes more sense to group it by semantics/properties, and then split in chunks still, which usually leads to chunks of ~6 ops. py/objtype: Make sure mp_binary_op_method_name has full size again. 2017-09-07T09:54:58+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-07T09:54:58+00:00 urn:sha1:6d4cac088eb29c7909f81121608546ca1b5e292e After recent refactorings to mp_binary_op_t, and make it future refactoring proof for now, at the cost of extra element in the array. py/runtime0.h: Move MP_BINARY_OP_DIVMOD to the end of mp_binary_op_t. 2017-09-07T08:26:42+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2017-09-07T08:26:42+00:00 urn:sha1:50b9329eba29a36b6948699aaea9473681d4f46b It starts a dichotomy of mp_binary_op_t values which can't appear in the bytecode. Another reason to move it is to VALUES of OP_* and OP_INPLACE_* nicely adjacent. This also will be needed for OP_REVERSE_*, to be soon introduced.
