* all: Use the name MicroPython consistently in commentsAlexander Steffen2017-07-31
| | | | | There were several different spellings of MicroPython present in comments, when there should be only one.
* py/scope: Factor common code to find locals and close over them.Damien George2016-09-30
| | | | Saves 50-100 bytes of code.
* py/scope: Use lookup-table to determine a scope's simple name.Damien George2016-09-30
| | | | Generates slightly smaller and more efficient code.
* py: Add MICROPY_ENABLE_COMPILER and MICROPY_PY_BUILTINS_EVAL_EXEC opts.Damien George2015-12-18
| | | | | | | | | | | | MICROPY_ENABLE_COMPILER can be used to enable/disable the entire compiler, which is useful when only loading of pre-compiled bytecode is supported. It is enabled by default. MICROPY_PY_BUILTINS_EVAL_EXEC controls support of eval and exec builtin functions. By default they are only included if MICROPY_ENABLE_COMPILER is enabled. Disabling both options saves about 40k of code size on 32-bit x86.
* unix-cpy: Remove unix-cpy. It's no longer needed.Damien George2015-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unix-cpy was originally written to get semantic equivalent with CPython without writing functional tests. When writing the initial implementation of uPy it was a long way between lexer and functional tests, so the half-way test was to make sure that the bytecode was correct. The idea was that if the uPy bytecode matched CPython 1-1 then uPy would be proper Python if the bytecodes acted correctly. And having matching bytecode meant that it was less likely to miss some deep subtlety in the Python semantics that would require an architectural change later on. But that is all history and it no longer makes sense to retain the ability to output CPython bytecode, because: 1. It outputs CPython 3.3 compatible bytecode. CPython's bytecode changes from version to version, and seems to have changed quite a bit in 3.5. There's no point in changing the bytecode output to match CPython anymore. 2. uPy and CPy do different optimisations to the bytecode which makes it harder to match. 3. The bytecode tests are not run. They were never part of Travis and are not run locally anymore. 4. The EMIT_CPYTHON option needs a lot of extra source code which adds heaps of noise, especially in compile.c. 5. Now that there is an extensive test suite (which tests functionality) there is no need to match the bytecode. Some very subtle behaviour is tested with the test suite and passing these tests is a much better way to stay Python-language compliant, rather than trying to match CPy bytecode.
* py, compiler: Refactor load/store/delete_id logic to reduce code size.Damien George2015-03-26
| | | | Saves around 230 bytes on Thumb2 and 750 bytes on x86.
* py: Remove unnecessary id_flags argument from emitter's load_fast.Damien George2015-01-16
| | | | Saves 24 bytes in bare-arm.
* py: Move to guarded includes, everywhere in py/ core.Damien George2015-01-01
| | | | Addresses issue #1022.
* py: Convert [u]int to mp_[u]int_t in emit.h and associated .c files.Damien George2014-09-08
| | | | Towards resolving issue #50.
* py: Include mpconfig.h before all other includes.Paul Sokolovsky2014-06-21
| | | | | | It defines types used by all other headers. Fixes #691.
* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

* | py: Remove unique_codes from emitglue.c. Replace with pointers.Damien George2014-04-13
|/ | | | | | | | | | | | | | | | 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.
* py: Properly implement deletion of locals and derefs, and detect errors.Damien George2014-04-09
| | | | | Needed to reinstate 2 delete opcodes, to specifically check that a local is not deleted twice.
* py: Clean up includes.xbe2014-03-17
| | | | Remove unnecessary includes. Add includes that improve portability.
* py: Remove name of var arg from macros with var args.Damien George2014-02-26

* Revamp qstrs: they now include length and hash.Damien George2014-01-21
| | | | | Can now have null bytes in strings. Can define ROM qstrs per port using qstrdefsport.h
* Change object representation from 1 big union to individual structs.Damien2013-12-21
| | | | | | | | | | 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).
