* py, unix, stmhal: Allow to compile with -Wshadow.Damien George2015-01-20
| | | | See issue #699.
* py: Implement very simple frozen modules support.Paul Sokolovsky2015-01-20
| | | | | Only modules (not packages) supported now. Source modules can be converted to frozen module structures using tools/make-frozen.py script.
* esp8266: Add missing hard_reset qstr.Paul Sokolovsky2015-01-18
|
* esp8266:modpyb: Implement hard_reset().Paul Sokolovsky2015-01-18
|
* unix: Update .gitignore for "fast" and "minimal" builds.Damien George2015-01-16
|
* unix: Add target to build "minimal" uPy interpreter.Damien George2015-01-16
|
* py, unix: Allow to compile with -Wsign-compare.Damien George2015-01-16
| | | | See issue #699.
* esp8266: Implement task-based, event-driven interface with UART.Paul Sokolovsky2015-01-16
| | | | | | This enables proper interfacing with underlying OS - MicroPython doesn't run the main loop, OS does, MicroPython just gets called when some event takes place.
* py: Remove unnecessary id_flags argument from emitter's load_fast.Damien George2015-01-16
| | | | Saves 24 bytes in bare-arm.
* minimal: Make #if indent consistent.Paul Sokolovsky2015-01-16
|
* minimal: Support even-driven REPL.Paul Sokolovsky2015-01-16
|
* pyexec: Add event-driven variant pyexec_friendly_repl().Paul Sokolovsky2015-01-16
| | | | | | | | | | pyexec_friendly_repl_process_char() and friends, useful for ports which integrate into existing cooperative multitasking system. Unlike readline() refactor before, this was implemented in less formal, trial&error process, minor functionality regressions are still known (like soft&hard reset support). So, original loop-based pyexec_friendly_repl() is left intact, specific implementation selectable by config setting.
* esp8266: Use dedicated heap allocated as static array.Paul Sokolovsky2015-01-15
| | | | | We cannot assume that all memory belongs to us - it actually belongs to ESP8266 OS.
* py: Add "default" to switches to allow better code flow analysis.Damien George2015-01-14
| | | | | This helps compiler produce smaller code. Saves 124 bytes on stmhal and bare-arm.
* py: Only allocate strings/bytes once for load_const_obj.Damien George2015-01-14
|
* unix, windows: Don't call mp_unix_mark_exec on windows.Damien George2015-01-14
|
* py: Allocate memory for assembled code at start of PASS_EMIT.Damien George2015-01-14
| | | | | Previously was allocating at end of PASS_COMPUTE, and this pass was being run twice, so memory was being allocated twice.
* travis, minimal: Install gcc-multilib for -m32; use /bin/echo for test.Damien George2015-01-14
|
* py: Reluctantly add an extra pass to bytecode compiler.Damien George2015-01-14
| | | | | | | | | | | | | | | Bytecode also needs a pass to compute the stack size. This is because the state size of the bytecode function is encoded as a variable uint, so we must know the value of this uint before we encode it (otherwise the size of the generated code changes from one pass to the next). Having an entire pass for this seems wasteful (in time). Alternative is to allocate fixed space for the state size (would need 3-4 bytes to be general, when 1 byte is usually sufficient) which uses a bit of extra RAM per bytecode function, and makes the code less elegant in places where this uint is encoded/decoded. So, for now, opt for an extra pass.
* py, unix: Trace root pointers with native emitter under unix port.Damien George2015-01-14
| | | | | | Native code has GC-heap pointers in it so it must be scanned. But on unix port memory for native functions is mmap'd, and so it must have explicit code to scan it for root pointers.
* py: Make compiler not crash when default except is not last.Damien George2015-01-13
|
* py/showbc.c: Handle new LOAD_CONST_OBJ opcode, and opcodes with cache.Damien George2015-01-13
|
* py: Never intern data of large string/bytes object; add relevant tests.Damien George2015-01-13
| | | | | | | | | | Previously to this patch all constant string/bytes objects were interned by the compiler, and this lead to crashes when the qstr was too long (noticeable now that qstr length storage defaults to 1 byte). With this patch, long string/bytes objects are never interned, and are referenced directly as constant objects within generated code using load_const_obj.
* py: Add load_const_obj to emitter, add LOAD_CONST_OBJ to bytecode.Damien George2015-01-13
| | | | | This allows to directly load a Python object to the Python stack. See issue #722 for background.
* minimal: Add simple test; build and run minimal test on Travis CI.Damien George2015-01-13
|
* minimal/Makefile: Remove unnecessary -I of py/ dir.Damien George2015-01-13
|
* minimal: Add "run" make target to run emulated build with suitable tty config.Paul Sokolovsky2015-01-13
|
* minimal: Convert "bare-arm" port to "minimal" port.Paul Sokolovsky2015-01-13
| | | | | This enable libc functions, GC, and line-editing function. Also, UART emulation for POSIX systems is added. Emulation build is set as default.
* minimal: New port, intended to represent minimal working code.Paul Sokolovsky2015-01-13
| | | | | | | | | Unlike bare-arm, which is mostly intended to show raw interpreter size, without library and support code dependencies. This port is intended to be a better base to start new ports, and also will include emulation build to allow debug some aspects of embedded targets on POSIX systems. This initial commit is verbatim copy of bare-arm code.

* qemu-arm: Disable basics/memoryerror.py test.Damien George2015-01-12
|
* stmhal: Add MICROPY_HW_USB_OTG_ID_PIN config, set for relevant boards.Damien George2015-01-12
| | | | | | | | | This config option is for the USB OTG pin, pin A10. This is used on some boards but not others. Eg PYBv3 uses PA10 for LED(2), so it shouldn't be used for OTG ID (actually PA10 is multiplexed on this board, but defaults to LED(2)). Partially addresses issue #1059.
* travis: grep for failure in qemu-arm output if tests fail.Damien George2015-01-12
|
* windows: Enable MICROPY_STACK_CHECK.Damien George2015-01-12

|
* lib/mp-readline: Refactor to support coroutine/event-driven usage.Paul Sokolovsky2015-01-12
| | | | | | readline_process_char() can be fed character by character, for example, received from external event loop. This will allow to integrate MicroPython into cooperative multitasking systems.
* teensy: Update for readline module moved to lib/.Paul Sokolovsky2015-01-12

* py/makeqstrdata.py: Make it work again with both Python2 and Python3.Damien George2015-01-11
|
* py: Add MICROPY_QSTR_BYTES_IN_LEN config option, defaulting to 1.Damien George2015-01-11
| | | | | | | | | | | | | | | | | | This new config option sets how many fixed-number-of-bytes to use to store the length of each qstr. Previously this was hard coded to 2, but, as per issue #1056, this is considered overkill since no-one needs identifiers longer than 255 bytes. With this patch the number of bytes for the length is configurable, and defaults to 1 byte. The configuration option filters through to the makeqstrdata.py script. Code size savings going from 2 to 1 byte: - unix x64 down by 592 bytes - stmhal down by 1148 bytes - bare-arm down by 284 bytes Also has RAM savings, and will be slightly more efficient in execution.
* py: Add qstr cfg capability; generate QSTR_NULL and QSTR_ from script.Damien George2015-01-11
|
* py: Remove unnecessary BINARY_OP_EQUAL code that just checks pointers.Damien George2015-01-11
| | | | | | | Previous patch c38dc3ccc76d1a9bf867704f43ea5d15da3fea7b allowed any object to be compared with any other, using pointer comparison for a fallback. As such, existing code which checked for this case is no longer needed.
* py: Implement fallback for equality check for all types.Damien George2015-01-11
| | | | | Return "not equal" for objects that don't implement equality check. This is as per Python specs.
* py: Add (commented out) code to gc_dump_alloc_table for qstr info.Damien George2015-01-11
