suspect-devices/circuitpython/py/runtime.c, branch v1.6CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.62016-01-29T00:13:42+00:00py/runtime: mp_stack_ctrl_init() should be called immediately on startup.2016-01-29T00:13:42+00:00Paul Sokolovskypfalcon@users.sourceforge.net2016-01-28T23:05:53+00:00urn:sha1:d3b1f0b627ccc6705d9fe958549badb87a74ded1
Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).
py: Change type of .make_new and .call args: mp_uint_t becomes size_t.2016-01-11T00:48:41+00:00Damien Georgedamien.p.george@gmail.com2016-01-03T09:59:18+00:00urn:sha1:a0c97814dfcb0debbde8be99539e3d5ca2334e54
This patch changes the type signature of .make_new and .call object method
slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more
efficient when mp_uint_t is larger than a machine word. Doesn't affect
ports when size_t and mp_uint_t have the same size.
py/runtime: Use appropriate printf fmt for malloc num_bytes.2016-01-08T13:49:58+00:00Damien Georgedamien.p.george@gmail.com2016-01-08T13:49:58+00:00urn:sha1:978d2e55efaeed26f4e9d4c21a10e41e4f150f72py: Be more restrictive binding self when looking up instance attrs.2015-12-26T12:41:31+00:00Damien Georgedamien.p.george@gmail.com2015-12-26T12:41:31+00:00urn:sha1:78913211a9532ff952f5628c7c94848bd59a4a11
When looking up and extracting an attribute of an instance, some
attributes must bind self as the first argument to make a working method
call. Previously to this patch, any attribute that was callable had self
bound as the first argument. But Python specs require the check to be
more restrictive, and only functions, closures and generators should have
self bound as the first argument
Addresses issue #1675.
py: Add MICROPY_ENABLE_COMPILER and MICROPY_PY_BUILTINS_EVAL_EXEC opts.2015-12-18T12:35:44+00:00Damien Georgedamien.p.george@gmail.com2015-12-18T12:35:44+00:00urn:sha1:dd5353a4054024a411aa343a22ffcd16195a16ad
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.
py: Make UNARY_OP_NOT a first-class op, to agree with Py not semantics.2015-12-10T22:19:48+00:00Damien Georgedamien.p.george@gmail.com2015-12-08T12:28:11+00:00urn: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: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.2015-11-29T14:25:35+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T17:01:44+00:00urn:sha1:999cedb90ff0827cdb9dfe0e4faa6ebc1739d271
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.
This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.
