suspect-devices/circuitpython/py/objfloat.c, branch v1.7CircuitPython - a Python implementation for teaching coding with microcontrollershttps://git.suspectdevices.com/suspect-devices/circuitpython/atom?h=v1.72016-01-11T00:49:27+00:00py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.2016-01-11T00:49:27+00:00Damien Georgedamien.p.george@gmail.com2016-01-03T15:55:55+00:00urn:sha1:5b3f0b7f39bd67cc9182993c288f09f67a0890df
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure. So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that). This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.
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: Add support for 64-bit NaN-boxing object model, on 32-bit machine.2015-11-29T14:25:36+00:00Damien Georgedamien.p.george@gmail.com2015-11-27T17:09:11+00:00urn:sha1:b8cfb0d7b2c91ea1e17f6caeabfc9cb23166cdc1
To use, put the following in mpconfigport.h:
#define MICROPY_OBJ_REPR (MICROPY_OBJ_REPR_D)
#define MICROPY_FLOAT_IMPL (MICROPY_FLOAT_IMPL_DOUBLE)
typedef int64_t mp_int_t;
typedef uint64_t mp_uint_t;
#define UINT_FMT "%llu"
#define INT_FMT "%lld"
Currently does not work with native emitter enabled.
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.
py: Add object repr "C", where 30-bit floats are stuffed in obj word.2015-10-20T11:38:54+00:00Damien Georgedamien.p.george@gmail.com2015-10-17T22:20:57+00:00urn:sha1:183edefddd8c08dd989fa7bec2d33d8b4130e1dc
This new object representation puts floats into the object word instead
of on the heap, at the expense of reducing their precision to 30 bits.
It only makes sense when the word size is 32-bits.
