This patch consolidates the Python logic for division/modulo to one place
within the bignum code.
py: Use MP_SMALL_INT_POSITIVE_MASK to check if uint fits in a small int.2016-03-10T21:52:56+00:00Damien Georgedamien.p.george@gmail.com2016-03-10T21:52:56+00:00urn:sha1:9ae51257bd40b1f010c2abbfb0a38b6d44860ea8
Using the original WORD_MSBIT_HIGH-logic resulted in errors when the
object model is not REPR_A or REPR_C.
py: Change mp_obj_int_is_positive to more general mp_obj_int_sign.2016-01-07T14:29:12+00:00Damien Georgedamien.p.george@gmail.com2016-01-07T14:29:12+00:00urn:sha1:d6b31e4578a9f7ed4f970774fe91eeb811b1d475
This function returns the sign (-1, 0 or 1) of the integer object.
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 mp_obj_is_float function (macro) and use it where appropriate.2015-10-20T11:35:17+00:00Damien Georgedamien.p.george@gmail.com2015-08-20T22:30:12+00:00urn:sha1:aaef1851a748af95f8b105ef2d1d4f35e6ede02bpy: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.2015-10-11T12:18:15+00:00Paul Sokolovskypfalcon@users.sourceforge.net2015-10-11T09:09:43+00:00urn:sha1:1b586f3a734c27c78080fb2173bbde17168cb9e4py: Catch all cases of integer (big and small) division by zero.2015-10-01T21:48:48+00:00Damien Georgedamien.p.george@gmail.com2015-10-01T21:48:48+00:00urn:sha1:e5635f4ab3d0fd00dd3951865fea82003205dae1py/mpz: Fix calculation of max digit storage for mpz; fix sys.maxsize.2015-09-15T15:15:57+00:00Damien Georgedamien.p.george@gmail.com2015-09-15T15:15:57+00:00urn:sha1:8b4fb4fe140e9cf57fcfa258d0d2d6fe19090fc5
When creating constant mpz's, the length of the mpz must be exactly how
many digits are used (not allocated) otherwise these numbers are not
compatible with dynamically allocated numbers.
Addresses issue #1448.
py: Implement divmod for mpz bignum.2015-06-13T22:38:28+00:00Damien Georgedamien.p.george@gmail.com2015-06-13T21:40:50+00:00urn:sha1:e9ce00d874ef6c93a56e726bb1503341f0448bf9py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.2015-05-12T21:46:02+00:00Damien Georgedamien.p.george@gmail.com2015-05-11T12:25:19+00:00urn:sha1:c2a4e4effc81d8ab21bb014e34355643e5ca0da2
Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
the operator argument. Hashing for int, str and bytes still go via
fast-path in mp_unary_op since they are the most common objects which
need to be hashed.
This lead to quite a bit of code cleanup, and should be more efficient
if anything. It saves 176 bytes code space on Thumb2, and 360 bytes on
x86.
The only loss is that the error message "unhashable type" is now the
more generic "unsupported type for __hash__".
