Nicko van Someren df0117c8ae py: Added optimised support for 3-argument calls to builtin.pow()
Updated modbuiltin.c to add conditional support for 3-arg calls to
pow() using MICROPY_PY_BUILTINS_POW3 config parameter. Added support in
objint_mpz.c for for optimised implementation.

Paul Sokolovsky bec7bfb29d py/objint: from_bytes(): Implement "byteorder" param and arbitrary precision.
If result guaranteedly fits in a small int, it is handled in objint.c.
Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should
be implemented by individual objint_*.c, similar to
mp_obj_int_to_bytes_impl().

Damien George e873243aa3 py/objint_mpz: Refactor switch-statement to remove unreachable default. 2017-01-19 23:35:45 +11:00
Damien George e4af712125 py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.
And also simplify it to remove the check for small int.  This can be done
because this function is only ever called if the argument is not a small
int.

Damien George 7d0d7215d2 py: Use mp_raise_msg helper function where appropriate.
Saves the following number of bytes of code space: 176 for bare-arm, 352
for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266.

Damien George 6dff3df501 py/objint: Use size_t for arguments that measure bytes/sizes. 2016-10-11 13:20:11 +11:00

Damien George 65402ab1ec py/mpz: Do Python style division/modulo within bignum divmod routine.
This patch consolidates the Python logic for division/modulo to one place
within the bignum code.

Damien George 9ae51257bd py: Use MP_SMALL_INT_POSITIVE_MASK to check if uint fits in a small int.
Using the original WORD_MSBIT_HIGH-logic resulted in errors when the
object model is not REPR_A or REPR_C.

Damien George d6b31e4578 py: Change mp_obj_int_is_positive to more general mp_obj_int_sign.
This function returns the sign (-1, 0 or 1) of the integer object.

Damien George 999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.
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.

Damien George e5635f4ab3 py: Catch all cases of integer (big and small) division by zero. 2015-10-01 22:48:48 +01:00
Damien George 8b4fb4fe14 py/mpz: Fix calculation of max digit storage for mpz; fix sys.maxsize.
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.

Damien George e9ce00d874 py: Implement divmod for mpz bignum. 2015-06-13 23:38:28 +01:00
Damien George c2a4e4effc py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.
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__".

Damien George 271d18eb08 py: Support conversion of bignum to bytes.
This gets int.to_bytes working for bignum, and also struct.pack with 'q'
and 'Q' args on 32-bit machines.

Addresses issue #1155.

Damien George ad2307c92c py: Temporary fix for conversion of float to int when fits in small int.
Addresses issue #1044 (see also #1040).  Could do with a better fix.

Addresses issue #1022.

Paul Sokolovsky 12033df511 py: Partially fix float to int conversion.
This fixes conversion when float type has more mantissa bits than small int,
and float value has small exponent. This is for example the case of 32-bit
platform using doubles, and converting value of time.time(). Conversion of
floats with larg exponnet is still not handled correctly.

Damien George be6d8be91e py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.
mp_obj_int_get_truncated is used as a "fast path" int accessor that
doesn't check for overflow and returns the int truncated to the machine
word size, ie mp_int_t.

Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word
sized values.

Addresses issues #779 and #998.

stijn 0e557facb9 mpz: Fix 64bit msvc build
msvc does not treat 1L a 64bit integer hence all occurences of shifting it left or right
result in undefined behaviour since the maximum allowed shift count for 32bit ints is 31.
Forcing the correct type explicitely, stored in MPZ_LONG_1, solves this.

Paul Sokolovsky 722e562736 py: Correctly set sys.maxsize value for 64-bit.
Type representing signed size doesn't have to be int, so use special value
which defaults to SSIZE_MAX, but as it's not defined by C standard (but rather
by POSIX), allow ports to set it.

Part of code cleanup, working towards resolving issue #50.
2014-08-30 14:19:41 +01:00
Damien George ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int.
Addressing issue #50, still some way to go yet.

Damien George c9aa58e638 py: Improve handling of long-int overflow.
This removes mpz_as_int, since that was a terrible function (it
implemented saturating conversion).

Use mpz_as_int_checked and mpz_as_uint_checked.  These now work
correctly (they previously had wrong overflow checking, eg
print(chr(10000000000000)) on 32-bit machine would incorrectly convert
this large number to a small int).

Paul Sokolovsky 4e0eeebdc2 py: Implement sys.maxsize, standard way to check platform "bitness".
Implementing it as a static constant is a bit peculiar and require cooperation
from long int implementation.

Paul Sokolovsky 3b6f7b95eb py: Separate MICROPY_PY_BUILTINS_COMPLEX from MICROPY_PY_BUILTINS_FLOAT.
One thing is wanting to do 1 / 2 and get something else but 0, and quite
another - doing rocket science ;-).
2014-06-20 18:00:23 +03:00
Damien George fb510b3bf9 Rename bultins config variables to MICROPY_PY_BUILTINS_*.
This renames:
MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE
MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT

See issue #35 for discussion.

Damien George 04b9147e15 Add license header to (almost) all files.
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/.
2014-05-03 23:27:38 +01:00
Paul Sokolovsky f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it.
Specifically, nlr.h does.

Damien George ea8d06c39d py: Add MP_OBJ_STOP_ITERATION and make good use of it.

This helps a lot in debugging and understanding of function API.
