Now, these types are all separate and any coding mistakes will be raised as runtime errors. py: Make UNARY_OP_NOT a first-class op, to agree with Py not semantics. 2015-12-10T22:19:48+00:00 Damien George damien.p.george@gmail.com 2015-12-08T12:28:11+00:00 urn:sha1:bdbe8c9ae21559f6dc0b8e1ad84b7bbec2a04726 Fixes #1684 and makes "not" match Python semantics. The code is also simplified (the separate MP_BC_NOT opcode is removed) and the patch saves 68 bytes for bare-arm/ and 52 bytes for minimal/. Previously "not x" was implemented as !mp_unary_op(x, MP_UNARY_OP_BOOL), so any given object only needs to implement MP_UNARY_OP_BOOL (and the VM had a special opcode to do the ! bit). With this patch "not x" is implemented as mp_unary_op(x, MP_UNARY_OP_NOT), but this operation is caught at the start of mp_unary_op and dispatched as !mp_obj_is_true(x). mp_obj_is_true has special logic to test for truthness, and is the correct way to handle the not operation. py/emit: Change type of arg of load_const_obj from void* to mp_obj_t. 2015-11-29T14:25:04+00:00 Damien George damien.p.george@gmail.com 2015-11-27T12:41:25+00:00 urn:sha1:5d66b427e22b6db5c73b74a6e9ba057ac5a38893 py: Add MICROPY_PERSISTENT_CODE so code can persist beyond the runtime. 2015-11-13T12:49:18+00:00 Damien George damien.p.george@gmail.com 2015-11-02T17:27:18+00:00 urn:sha1:c8e9c0d89afa90694790fd48e1bf527487a5beb7 Main changes when MICROPY_PERSISTENT_CODE is enabled are: - qstrs are encoded as 2-byte fixed width in the bytecode - all pointers are removed from bytecode and put in const_table (this includes const objects and raw code pointers) Ultimately this option will enable persistence for not just bytecode but also native code. py: Add constant table to bytecode. 2015-11-13T12:49:18+00:00 Damien George damien.p.george@gmail.com 2015-10-23T00:23:11+00:00 urn:sha1:713ea1800d1f0c82a0c75885ad034705556ab5ef Contains just argument names at the moment but makes it easy to add arbitrary constants.
