2004-04-07  Kevin Ryde  <kevin@swox.se>

	* mpn/x86/k6/gcd_finda.asm: Correction jbe -> jb in initial setups.
	Zero flag is wrong here, it relects only the high limb of the compare,
	leading to n1>=n2 not satisfied and wrong results.  cp[1]==0x7FFFFFFF
	with cp[0]>=0x80000001 provokes this.

	* doc/gmp.texi (BSD Compatible Functions): Note "pow" name clash under
	the pow function description too.
	(Language Bindings): Add XEmacs (betas at this stage).  Reported by
	Jerry James.

	* tests/refmpn.c (refmpn_mod2): Correction to ASSERTs, r==a is allowed.

	* gen-psqr.c (generate_mod): Cast mpz_invert_ui_2exp args, for K&R.
	* gen-bases.c, gen-fib.c, gen-psqr.c: For mpz_out_str, use stdout
	instead of 0, in case a K&R treats int and FILE* params differently.

2004-04-04  Kevin Ryde  <kevin@swox.se>

	* gmp-impl.h (BSWAP_LIMB) [amd64]: New macro.

	* mpn/amd64/divrem_1.asm: New file.

2004-03-20  Kevin Ryde  <kevin@swox.se>

	* longlong.h (power, powerpc): Add comments on how we select this code.

	* gmp-h.in (mpz_get_ui): Use ?: instead of mask style, gcc treats the
	two identically but ?: is a bit clearer.

	* insert-dbl.c: Remove file, no longer used, scaling is now integrated
	in mpn_get_d.
	* Makefile.am (libgmp_la_SOURCES): Remove insert-dbl.c.
	* gmp-impl.h (__gmp_scale2): Remove prototype.

2004-03-17  Kevin Ryde  <kevin@swox.se>

	* tests/mpf/t-mul_ui.c: New file.
	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.

	* mpf/div.c: Use mpn_tdiv_qr.  Use just one TMP_ALLOC.  Use full
	divisor, since truncating can lose accuracy.

	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.

	* tests/mpf/t-set_q.c, tests/mpf/t-ui_div.c (check_various): Amend
	bogus 99/4 test.

	* tests/refmpf.c, tests/tests.h (refmpf_set_overlap): New function.

	* mpf/cmp_si.c [nails]: Correction, cast vval in exp comparisons, for
	when vval=-0x800..00 and limb==longlong.

	* mpf/cmp_si.c [nails]: Correction, return usign instead of 1 when
	uexp==2 but value bigger than an mp_limb_t.
	* tests/mpf/t-cmp_si.c (check_data): Add test cases.

	* tests/trace.c (mpf_trace): Use ABS(mp_trace_base) to allow for
	negative bases used for upper case hex in integer traces.

2004-03-12  Torbjorn Granlund  <tege@swox.com>

	* mpn/generic/sb_divrem_mn.c: Correct header comment.

2004-03-11  Kevin Ryde  <kevin@swox.se>

	* aclocal.m4, configure, ltmain.sh: Downgrade to libtool 1.5, version
	1.5.2 doesn't remove .libs/*.a files when rebuilding, which is bad for
	development when changing contents or with duplicate named files like
	we have.

	Revert this, ie restore AR_FLAGS=cq:
	* acinclude.m4 (GMP_PROG_AR): Remove AR_FLAGS=cq, libtool 1.5.2 now
	does this itself on detecting duplicate object filenames in piecewise
	linking mode.

	* randbui.c, randmui.c [longlong+nails]: Correction to conditionals
	for second limb.

	* mpz/aors_ui.h, mpz/cdiv_q_ui.c, mpz/cdiv_qr_ui.c, mpz/cdiv_r_ui.c,
	mpz/cdiv_ui.c, mpz/fdiv_q_ui.c, mpz/fdiv_qr_ui.c, mpz/fdiv_r_ui.c,
	mpz/fdiv_ui.c, mpz/gcd_ui.c, mpz/iset_ui.c, mpz/lcm_ui.c,
	mpz/set_ui.c, mpz/tdiv_q_ui.c, mpz/tdiv_qr_ui.c, mpz/tdiv_r_ui.c,
	mpz/tdiv_ui.c, mpz/ui_sub.c, mpf/div_ui.c, mpf/mul_ui.c
	[longlong+nails]: Amend #if to avoid warnings about shift amount.

2004-03-07  Kevin Ryde  <kevin@swox.se>

	* mpf/reldiff.c: Use rprec+ysize limbs for d, to ensure accurate
	result.  Inline mpf_abs(d,d) and mpf_cmp_ui(x,0), and rate the latter
	UNLIKELY.

	* mpf/ui_div.c: Use mpn_tdiv_qr.  Use just one TMP_ALLOC.  Use full
	divisor, since truncating can lose accuracy.
	* tests/mpf/t-ui_div.c: New file.
	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.

	* mpf/set_q.c: Expand TMP_ALLOC_LIMBS_2, to make conditional clearer
	and avoid 1 limb alloc when not wanted.

	* gmp-impl.h (WANT_TMP_DEBUG): Define to 0 if not defined.
	(TMP_ALLOC_LIMBS_2): Use "if" within macro rather than "#if", for less
	preprocessor conditionals.

	* mpf/mul_2exp.c, mpf/div_2exp.c: Add some comments.

	* tests/refmpn.c (refmpn_sb_divrem_mn, refmpn_tdiv_qr): Nailify.

2004-03-04  Kevin Ryde  <kevin@swox.se>

	* gen-psqr.c (print): Add CNST_LIMB in PERFSQR_MOD_TEST, for benefit
	of K&R.
	* tests/mpn/t-perfsqr.c (PERFSQR_MOD_1): Use CNST_LIMB for K&R.

	* doc/configuration (Configure): Remove mkinstalldirs, no longer used.

	* acinclude.m4 (GMP_PROG_AR): Remove AR_FLAGS=cq, libtool 1.5.2 now
	does this itself on detecting duplicate object filenames in piecewise
	linking mode.

	* configure.in (hppa2.0*-*-*): Test sizeof(long) == 4 or 8 to verify
	ABI=2.0n versus ABI=2.0w.  In particular this lets CC=cc_bundled
	correctly fall back to ABI=2.0n (we don't automatically add CC=+DD64
	to that compiler, currently).

	* doc/gmp.texi (Reentrancy): Note C++ mpf_class constructors using
	global default precision.
	(Random State Miscellaneous): Describe gmp_urandomb_ui as giving N
	bits.
	(C++ Interface Floats): Describe operator= copying the value, not the
	precision, and what this can mean about copy constructor versus
	default constructor plus assignment.

	* mpf/set_q.c: Use mpn_tdiv_qr rather than mpn_divrem, so no shifting.
	Don't truncate the divisor, it can make the result inaccurate.
	* tests/mpf/t-set_q.c: New file.
	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.

	* mpf/set.c: Use MPN_COPY_INCR, in case r==u and ABSIZ(u) > PREC(r)+1.
	No actual bug here, because MPN_COPY has thusfar been an alias for
	MPN_COPY_INCR, only an ASSERT failure.
	* tests/mpf/t-set.c: New file.
	* tests/mpf/Makefile.am (check_PROGRAMS): Add it.

	* mpf/set.c, mpf/iset.c: Do MPN_COPY last, for possible tail call.

	* mpf/set_d.c: Rate d==0 as UNLIKELY.  Store size before extract call,
	to shorten lifespan of "negative".

	* mpf/init.c, mpf/init2.c, mpf/iset_d.c, mpf/iset_si.c,
	mpf/iset_str.c, mpf/iset_ui.c: Store prec before alloc call, for one
	less live quantity across that call.
	* mpf/init.c, mpf/init2.c, mpf/iset_str.c: Store size and exp before
	alloc call, to overlap with other operations.

	* tests/refmpf.c, tests/tests.h (refmpf_fill, refmpf_normalize,
	refmpf_validate, refmpf_validate_division): New functions.

	* tests/refmpn.c, tests/tests.h (refmpn_copy_extend,
	refmpn_lshift_or_copy_any, refmpn_rshift_or_copy_any): New functions.

	* tal-debug.c: Add <string.h> for strcmp.

	* tests/cxx/t-istream.cc (check_mpz, check_mpq, check_mpf): Use size_t
	for loop index, to quieten g++ warning.

2004-03-02  Kevin Ryde  <kevin@swox.se>

	* tests/mpn/t-hgcd.c: Use __GMP_PROTO on prototypes.

2004-03-01  Torbjorn Granlund  <tege@swox.com>

	With Karl Hasselström:
	* mpn/generic/dc_divrem_n.c (mpn_dc_div_2_by_1): New function, with
	meat from old mpn_dc_divrem_n.  Accept scratch parameter.  Rewrite to
	avoid a recursive call.
	(mpn_dc_div_3_by_2): New function, with meat from old
	mpn_dc_div_3_halves_by_2.  Accept scratch parameter.
	(mpn_dc_divrem_n): Now just allocate scratch space and call new
	mpn_dc_div_2_by_1.

2004-02-29  Kevin Ryde  <kevin@swox.se>

	* longlong.h (count_leading_zeros) [alpha gcc]: New version, inlining
	mpn/alpha/cntlz.asm cmpbge technique.

	* aclocal.m4, configure, install-sh, missing, ltmain.sh,
	*/Makefile.in: Update to automake 1.8.2 and libtool 1.5.2.

	* doc/gmp.texi (C++ Interface Integers): Note / and % rounding follows
	C99 / and %.
	(Exact Remainder): Index entries for divisibility testing algorithm.

	* tune/time.c (speed_endtime): Return 0.0 for negative time measured.
	Revise usage comments for clarity.

	usual way.

2004-02-24  Torbjorn Granlund  <tege@swox.com>

	From Kevin:
	* mpn/generic/mul_fft.c (mpn_fft_add_modF): Loop until normalization
	criterion met.

2004-02-22  Kevin Ryde  <kevin@swox.se>

	* acinclude.m4 (GMP_PROG_CC_WORKS, GMP_OS_X86_XMM, GMP_PROG_CXX_WORKS):
	Remove files that might look like compiler output, so our "||"
	alternatives are not fooled.

	* acinclude.m4 (GMP_PROG_CC_WORKS): Add test for lshift_com code
	mis-compiled by certain IA-64 HP cc at +O3.

	* gmp-impl.h (USE_LEADING_REGPARM): Disable under prof or gprof, for
	the benefit of freebsd where .mcount clobbers registers.  Spotted by
	Torbjorn.
	* configure.in (WANT_PROFILING_PROF, WANT_PROFILING_GPROF): New
	AC_DEFINEs.

2004-02-21  Kevin Ryde  <kevin@swox.se>

	* configure.in (sparc64-*-*bsd*): Amend -m32 setup for ABI=32, so it's
	not used in ABI=64 on the BSD systems.

2004-02-18  Niels Möller  <nisse@lysator.liu.se>

	* tests/mpz/t-gcd.c (gcdext_valid_p): New function.
	(ref_mpz_gcd): Deleted function.
	(one_test): Rearranged to call mpz_gcdext first, so that the
	returned value can be validated.
	(main): Don't use ref_mpz_gcd.

2004-02-18  Torbjorn Granlund  <tege@swox.com>

	* gmp-impl.h (MPN_TOOM3_MAX_N): Move to !WANT_FFT section.

	* tests/mpz/t-mul.c: Exclude special huge operands unless WANT_FFT.

	* mpz/rrandomb.c (gmp_rrandomb): Rewrite.

	* gmp-impl.h (MP_EXP_T_MAX, MP_EXP_T_MIN): New defines.

	* mpf/get_ui.c, mpf/get_si.c: Remove size==0 test, it's covered by
	other conditions.  Attempt greater clarity by expressing conditions as
	based on available data range.
	* mpf/get_si.c [nails]: Correction, don't bail on exp > abs_size,
	since may still have second limb above radix point available.
	* mpf/get_ui.c: Nailify.

2004-02-16  Kevin Ryde  <kevin@swox.se>

	* mpz/scan0.c, mpz/scan1.c: Use count_trailing_zeros, instead of
	count_leading_zeros on limb&-limb.

	* mpf/sqrt.c: Use "/ 2" for exp, avoiding C undefined behaviour on
	">>" of negatives.  Correction to comment, exp is rounded upwards.
	SIZ(r) always prec now, no need for tsize expression.  Store EXP(r)
	and SIZ(r) where calculated to reduce variable lifespans.  Make tsize
	mp_size_t not mp_exp_t, though of course those are currently the same.

	* gmp-h.in (GMP_ERROR_ALLOCATE, GMP_ERROR_BAD_STRING,
	GMP_ERROR_UNUSED_ERROR): Remove, never used or documented, and we
	don't want to use globals for communicating error information.

	* mpz/gcd_ui.c [nails]: Correction, actually return a value.

	* mpn/generic/addmul_1.c, mpn/generic/submul_1.c [nails==1]: Add code.

	concerned about.

	* mpn/generic/mul_n.c: Add some remarks about toom3 high zero
	stripping.

	* mpn/generic/scan0.c, mpn/generic/scan1.c: Remove design issue
	remarks.  What to do about going outside `up' space is a problem, but
	anything to address it would be an incompatible change.

2004-02-12  Torbjorn Granlund  <tege@swox.com>

	* tests/mpn/t-hgcd.c: Remove unused variables.

	* gmp-impl.h: Add remarks about limits.h and Cray etc.

	* mpn/ia64/mul_1.asm: Don't put .pred directives on labelled lines,
	hpux 11.23 assembler doesn't like that.
	* mpn/ia64/README: Add a note on this.

	* dumbmp.c (mpz_mul): Set ALLOC(r) for new data block used.  Reported
	by Jason Moxham.

	* mpz/get_d_2exp.c, mpf/get_d_2exp.c: Remove x86+m68k force to double,
	mpn_get_d now does this.  Remove res==1.0 check for round upwards,
	mpn_get_d now rounds towards zero.  Move exp store to make mpn_get_d a
	tail call.

	* configure.in (x86-*-*): Use ABI=32 rather than ABI=standard.
	Use gcc -m32 when available, to force mode on bi-arch amd64 gcc.
	* configure.in, acinclude.m4 (x86_64-*-*): Merge into plain x86 setups
	as ABI=64.  Support ABI=32, using athlon code.  Use gcc -mcpu=k8,

	(gcd_schoenhage): Deleted assertion code using mpn_hgcd_lehmer.

	* mpn/generic/hgcd.c (hgcd_final): Fixed ASSERT typos.
	(mpn_hgcd): To use Lehmer's algorithm, call hgcd_final directly,
	not mpn_hgcd_lehmer.

	* mpn/generic/gcd.c (gcd_schoenhage): Updated for changes to
	mpn_hgcd and mpn_hgcd_fix. (Schoenhage code is still disabled).

	* gmp-impl.h (mpn_hgcd_fix): Updated prototype.

	* mpn/generic/hgcd.c (mpn_hgcd_fix): Replaced a bunch of arguments
	by a pointer const struct hgcd_row *s. Updated callers.

	Moved function definition before hgcd_jebelean.
	(hgcd_jebelean): Interface change, analogous to hgcd2.
	(mpn_hgcd_fix): Normalize v. Require that v > 0.
	(hgcd_adjust): Fix bug in carry update.
	(mpn_hgcd): Reorganized again, to adapt to mpn_hgcd/hgcd_jebelean

	(hgcd_ref_init, hgcd_ref_clear): New functions.

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 multiplication.

	* 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.)
