* _mpz_realloc: Make it accept size in number of mp_digits.
* Most functions: Use new _mpz_realloc definition.
* mpz_set_str: Remove calls _mp_free_func.
* Most functions: Rename mpn_* to _mpn_*. Rename mpz_realloc to
_mpz_realloc.
* mpn_lshift: Redefine _mpn_lshift to only handle small shifts.
* mdiv, mpz_div, ...: Changes for new definition of _mpn_lshift.
* msqrt, mp*_*shift*: Define cnt as unsigned (for speed).
Sat Apr 6 14:05:16 1991 Torbjorn Granlund (tege@musta.nada.kth.se)
* mpn_mul: Multiply by the first digit in M2 in a special
loop instead of zeroing the product area.
* mpz_abs.c: New file.
* sdiv: Implement as mpz_div_si for speed.
* mpn_add: Make it work for second source operand == 0.
* msub: Negate the correct operand, i.e. V before swapping, not
the smaller of U and V!
* madd, msub: Update abs_* when swapping operands, and not after
(optimization).
Fri Apr 5 00:19:36 1991 Torbjorn Granlund (tege@black.nada.kth.se)
* mpn_sub: Make it work for subtrahend == 0.
* madd, msub: Rewrite to minimize mpn_cmp calls. Ensure
mpn_cmp is called with positive sizes (used to be called
incorrectly with negative sizes sometimes).
* msqrt: Make it divide by zero if fed with a negative number.
* Remove if statement at end of precision calculation that was
never true.
* itom, mp.h: The argument is of type short, not int.
* mpz_realloc, gmp.h: Make mpz_realloc return the new digit pointer.
* mpz_get_str.c, mpz_set_str.c, mpz_new_str.c: Don't include mp.h.
* Add COPYING to distribution.
* mpz_div_ui.c, mpz_div_si.c, mpz_new_ui.c, mpz_new_si.c: New files.
Fri Mar 15 00:26:29 1991 Torbjorn Granlund (tege@musta.nada.kth.se)
* Add Copyleft headers to all files.
* mpn_mul.c, mpn_div.c: Add header comments.
* mult.c, mdiv.c: Update header comments.
* mpq_add.c, mpq_sub.c, mpq_div.c, mpq_new.c, mpq_new_ui.c,
mpq_free.c: New files for rational arithmetics.
* mpn_lshift.c: Avoid writing the most significant word if it is 0.
* mdiv.c: Call mpn_lshift for the normalization.
* mdiv.c: Remove #ifdefs.
* Makefile: Add ChangeLog to DISTFILES.
* mpn_div.c: Make the add_back code work (by removing abort()).
* mpn_div.c: Make it return if the quotient is size as compared
with the difference NSIZE - DSIZE. If the stored quotient is
larger than that, return 1, otherwise 0.
* gmp.h: Fix mpn_div declaration.
* mdiv.c: Adopt call to mpn_div.
* mpz_div.c: New file (developed from mdiv.c).
* README: Update routine names.
Thu Mar 14 18:45:28 1991 Torbjorn Granlund (tege@musta.nada.kth.se)
* mpq_mul.c: New file for rational multplication.
* gmp.h: Add definitions for rational arithmetics.
* mpn_div: Kludge the case where the high numerator digit > the
high denominator digit. (This code is going to be optimized later.)
* New files: gmp.h for GNU specific functions, gmp-common.h for
definitions common for mp.h and gmp.h.
* Ensure mp.h just defines what BSD mp.h defines.
* pow.c: Fix typo for bp allocation.
* Rename natural number functions to mpn_*, integer functions to
mpz_*.
Tue Mar 5 18:47:04 1991 Torbjorn Granlund (tege@musta.nada.kth.se)
* mdiv.c (_mp_divide, case 2): Change test for estimate of Q from
"n0 >= r" to "n0 > r".
* msqrt: Tune the increasing precision scheme, to do fewer steps.
Tue Mar 3 18:50:10 1991 Torbjorn Granlund (tege@musta.nada.kth.se)
* msqrt: Use the low level routines. Use low precision in the
beginning, and increase the precision as the result converges.
(This optimization gave a 6-fold speedup.)
