Issue #4258: Make it possible to use 30-bit digits for PyLongs:
- new configure option --enable-big-digits - new structseq sys.int_info giving information about the internal format By default, 30-bit digits are enabled on 64-bit machines but disabled on 32-bit machines.

* Integers are now stored internally either in base 2**15 or in base
|
||||
2**30, the base being determined at build time. Previously, they
|
||||
were always stored in base 2**15. Using base 2**30 gives
|
||||
significant performance improvements on 64-bit machines, but
|
||||
benchmark results on 32-bit machines have been mixed. Therefore,
|
||||
the default is to use base 2**30 on 64-bit machines and base 2**15
|
||||
on 32-bit machines; on Unix, there's a new configure option
|
||||
--enable-big-digits that can be used to override this default.
|
||||
|
||||
Apart from the performance improvements this change should be
|
||||
invisible to end users, with one exception: for testing and
|
||||
debugging purposes there's a new structseq ``sys.int_info`` that
|
||||
provides information about the internal format, giving the number of
|
||||
bits per digit and the size in bytes of the C type used to store
|
||||
each digit::

should be an unsigned integer type able to hold all integers up to

value of PyLong_SHIFT, but there are some notable exceptions:

- long_pow() requires that PyLong_SHIFT be divisible by 5
|
||||
|
||||
- PyLong_{As,From}ByteArray require that PyLong_SHIFT be at least 8
|
||||
|
||||
- long_hash() requires that PyLong_SHIFT is *strictly* less than the number
|
||||
of bits in an unsigned long, as do the PyLong <-> long (or unsigned long)
|
||||
conversion functions
|
||||
|
||||
- the long <-> size_t/Py_ssize_t conversion functions expect that
|
||||
PyLong_SHIFT is strictly less than the number of bits in a size_t
|
||||
|
||||
- the marshal code currently expects that PyLong_SHIFT is a multiple of 15
|
||||
|
||||
- NSMALLNEGINTS and NSMALLPOSINTS should be small enough to fit in a single
|
||||
digit; with the current values this forces PyLong_SHIFT >= 9
|

The values 15 and 30 should fit all of the above requirements, on any
