LwIP support, and preliminary implementation of persistent bytecode This release includes the lwip network stack module with slip support. There is a preliminary implementation of persistent bytecode which allows to save compiled bytecode to a .mpy file, to be loaded at a later time by another MicroPython instance. Double precision floating-point formatting is now provided by the core, and the bundled upip module is no longer dependent on FFI. stmhal port has improved RTC startup. There are many bug fixes and improvements to the documentation. py core: - makeversionhdr.py works with backslashes in paths - in inline asm, vldr and vstr offsets now in bytes not words - modstruct: support repetition counters for all types, not just string - add py/mphal.h and use it in all ports - adjust object repr C (30-bit stuffed float) to reduce code size - clear finalizer flag when calling gc_free - objint_longlong: instead of assert, throw OverflowError - asmthumb: allow to compile with -Wsign-compare and -Wunused-parameter - emitinlinethumb: allow to compile with -Wsign-compare - reorganise bytecode layout so it's more structured, easier to edit - put all bytecode state (arg count, etc) in bytecode - add constant table to bytecode - add MICROPY_PERSISTENT_CODE so code can persist beyond the runtime - add MICROPY_PERSISTENT_CODE_LOAD/SAVE to load/save bytecode - allow to import compiled bytecode files -

in mp_state_ctx_t, make mp_pending_exception volatile - store key/value in earliest possible slot in hash table - add Cygwin support to py/nlrx86.S - add mp_compile_to_raw_code() to return raw code object - emitglue: add mp_raw_code_load_mem to load raw-code from memory - emitglue: host definition of mp_verbose_flag - formatfloat: convert to fully portable implementation - formatfloat: fix incorrect rounding for %f format - formatfloat: handle calculation of integer digit for %f format properly - mpz: normalize xor operation result to fix bugs in comparisons - emitglue: add feature-flag header to .mpy to detect bytecode compat -
