Damien George 88d7bba961 py: Make it so that printing a small int does not allocate heap memory.
With the implementation of proper string formatting, code to print a
small int was delegated to mpz_as_str_inpl (after first converting the
small int to an mpz using stack memory).  But mpz_as_str_inpl allocates
heap memory to do the conversion, so small ints needed heap memory just
to be printed.

This fix has a separate function to print small ints, which does not
allocate heap, and allocates less stack.

String formatting, printf and pfenv are now large beasts, with some
semi-duplicated code.

Dave Hylands c4029e5079 Add string formatting support for longlong and mpz. 2014-04-07 11:38:45 -07:00
Damien George ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging.
This does not affect code size or performance when debugging turned off.

To address issue #420.

Damien George ecf5b77123 py: This time, real proper overflow checking of small int power.
Previous overflow test was inadequate.

Damien George d17926db71 Rename rt_* to mp_*.
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

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).

Damien George 06201ff3d6 py: Implement bit-shift and not operations for mpz.
Implement not, shl and shr in mpz library.  Add function to create mpzs
on the stack, used for memory efficiency when rhs is a small int.
Factor out code to parse base-prefix of number into a dedicated function.

Damien George 438c88dd2f Add arbitrary precision integer support.
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).
