2014-04-13py: Remove unique_codes from emitglue.c. Replace with pointers.Damien George
Attempt to address issue #386. unique_code_id's have been removed and replaced with a pointer to the "raw code" information. This pointer is stored in the actual byte code (aligned, so the GC can trace it), so that raw code (ie byte code, native code and inline assembler) is kept only for as long as it is needed. In memory it's now like a tree: the outer module's byte code points directly to its children's raw code. So when the outer code gets freed, if there are no remaining functions that need the raw code, then the children's code gets freed as well. This is pretty much like CPython does it, except that CPython stores indexes in the byte code rather than machine pointers. These indices index the per-function constant table in order to find the relevant code.
2014-04-10py: Simplify stack get/set to become stack adjust in emitters.Damien George
Can do this now that the stack size calculation is improved.
2014-04-10py, compiler: Improve stack depth counting.Damien George
Much less of a hack now. Hopefully it's correct!
2014-04-10py: Make labels unsigned ints (converted from int).Damien George
Labels should never be negative, and this modified type signature reflects that.
2014-04-09py: Oops, fix emitcpy to compile with latest changes.Damien George
2014-04-09py, compile: Combine have_star_arg, have_dbl_star_arg into star_flags.Damien George
Small reduction in ROM, heap and stack usage.
2014-04-02py: Move to Python 3.4.0 compatibility.Damien George
Very little has changed. In Python 3.4 they removed the opcode STORE_LOCALS, but in Micro Python we only ever used this for CPython compatibility, so it was a trivial thing to remove. It also allowed to clean up some dead code (eg the 0xdeadbeef in class construction), and now class builders use 1 less stack word. Python 3.4.0 introduced the LOAD_CLASSDEREF opcode, which I have not yet understood. Still, all tests (apart from bytecode test) still pass. Bytecode tests needs some more attention, but they are not that important anymore.
2014-03-31py: Rename and reorder parameters in emit_make_function/closure.Damien George
In preparation for implementing default keyword arguments.
2014-03-30Rename rt_* to mp_*.Damien George
Mostly just a global search and replace. Except rt_is_true which becomes mp_obj_is_true. Still would like to tidy up some of the names, but this will do for now.
2014-03-17py: Clean up includes.xbe
Remove unnecessary includes. Add includes that improve portability.
2014-02-16Propagate scope flags refactor to emitcpy.c.Paul Sokolovsky
2014-02-12Replace global "static" -> "STATIC", to allow "analysis builds". Part 2.Paul Sokolovsky
2014-02-01py: Tidy up BINARY_OPs; negation done by special NOT bytecode.Damien George
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new special NOT bytecode.
2014-02-01py: Fix emitcpy so continue is compatible with CPython.Damien George
2014-01-29py: Fix bug with LOAD_METHOD; fix int->machine_int_t for small int.Damien George
LOAD_METHOD bug was: emitbc did not correctly calculate the amount of stack usage for a LOAD_METHOD operation. small int bug was: int was being used to pass small ints, when it should have been machine_int_t.
2014-01-25Implement mp_parse_node_free; print properly repr(string).Damien George
2014-01-24py: Improve freeing of emitters in mp_compile.Damien George
There can be multiple emitters allocated during compile (eg byte code and native).
2014-01-24Add support for freeing code emitter objects at the end of compilation.Paul Sokolovsky
2014-01-21Revamp qstrs: they now include length and hash.Damien George
Can now have null bytes in strings. Can define ROM qstrs per port using qstrdefsport.h
2014-01-18Add source file name and line number to error messages.Damien George
Byte code has a map from byte-code offset to source-code line number, used to give better error messages.
2014-01-11py: Fix emitcpy and emitnative's binary_op.Damien George
2014-01-11unified the bopsJohn R. Lenton
2014-01-04Improve configurability for native x64/thumb emitter.Damien George
With MICROPY_EMIT_X64 and MICROPY_EMIT_THUMB disabled, the respective emitters and assemblers will not be included in the code. This can significantly reduce binary size for unix version.
2014-01-03Change mp_compile so that it returns a function object for the module.Damien George
2013-12-29Add unix-cpy, used to test Micro Python byte code against CPython.Damien
2013-12-21Change object representation from 1 big union to individual structs.Damien
A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
