Paul Sokolovsky b3be4710aa py/mpz: Normalize (remove leading zeros) xor operation result. 2015-11-22 22:03:18 +02:00
Damien George 2065373f67 py/mpz: Fix bignum anding of large negative with smaller positive int. 2015-10-01 22:35:06 +01:00
Damien George 2f4e8511cd py/mpz: Force rhs of mpz_shl_inpl/mpz_shr_inpl to be unsigned.
Python semantics are that rhs of shift must be non-negative, so there's
no need to handle negative values in the underlying mpz implementation.

Damien George 4c02e54298 py/mpz: Raise NotImplError instead of failing assertion. 2015-10-01 17:57:36 +01:00
Damien George 9472907ae1 py: Fix handling of negative numbers in struct.pack of q/Q. 2015-04-25 23:51:14 +01:00
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.

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.

Damien George 9a21d2e070 py: Make mpz able to use 16 bits per digit; and 32 on 64-bit arch.
Previously, mpz was restricted to using at most 15 bits in each digit,
where a digit was a uint16_t.

With this patch, mpz can use all 16 bits in the uint16_t (improvement
to mpn_div was required).  This gives small inprovements in speed and
RAM usage.  It also yields savings in ROM code size because all of the
digit masking operations become no-ops.

Also, mpz can now use a uint32_t as the digit type, and hence use 32
bits per digit.  This will give decent improvements in mpz speed on
64-bit machines.

Test for big integer division added.

Damien George 5d9b816449 py: Fix bug in mpn_shl (multi-prec int shift left).
Before this patch, eg, 1 << 75 (or any large multiple of 15) was setting
the MSB in the digits, which is outside the valid range of DIG_MASK.

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).

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/.

Paul Sokolovsky 57207b8818 objint_mpz: Quick&dirty implementation of bitwise operations.
Made solely to unbreak int-long.py test which in turn uncovered thinko
with implementation of inplace ops. On mpz level, bitwise ops implemented
only for same-sign numbers, and are not efficient (unconditional calling of
mpn_cmp() is apparently superfluous).
