2004-05-07  Kevin Ryde  <kevin@swox.se>

        * tests/cxx/Makefile.am (TESTS_ENVIRONMENT): Amend c++ shared library
        path hack, on k62-unknown-dragonfly1.0 /usr/bin/make runs its commands
        "set -e", so we need an "|| true" in case there's nothing to copy (for
        instance in a static build).

2004-05-06  Kevin Ryde  <kevin@swox.se>

        * mpn/alpha/mode1o.c: Remove, in favour of ...
        * mpn/alpha/mode1o.asm: New file.
        * mpn/alpha/alpha-defs.m4 (bwx_available_p): New macro.

        * tune/amd64.asm: Save rbx in r10 rather than on the stack.

        * configure.in (x86_64-*-*): Try also "-march=k8 -mno-sse2", in case
        we're in ABI=32 on an old OS not supporting xmm regs.
        (GMP_GCC_PENTIUM4_SSE2, GMP_OS_X86_XMM): Run these tests under
        -march=k8 too, and not under ABI=64.

        * doc/gmp.texi (Converting Integers): For mpz_get_d, note truncation
        and overflows.  For mpz_get_d_2exp note truncation, note result if
        OP==0, and cross reference libc frexp.
        (Rational Conversions): For mpq_get_d, note truncation and overflows.
        (Converting Floats): For mpf_get_d, note truncation and overflows.
        For mpf_get_d_2exp, note truncation, note result if OP==0.
        (Assembler Code Organisation): Note nails subdirectories.
        Clarification of get_d_2exp OP==0 reported by Sylvain Pion.

2004-05-05  Torbjorn Granlund  <tege@swox.com>

        * mpn/generic/mullow_n.c, mpn/generic/mullow_basecase.c: New files
        (mainly by Niels Möller).
        * configure.in, mpn/Makefile.am: Add them.

2004-05-02  Kevin Ryde  <kevin@swox.se>

        * mpn/amd64/mode1o.asm: Use movabsq to support large model non-PIC.
        Use 32-bit insns to save code bytes, and to save a couple of cycles on
        the initial setup multiplies.

2004-05-01  Kevin Ryde  <kevin@swox.se>

        * doc/gmp.texi (References): Update gcc online docs url to
        gcc.gnu.org.

        * configure.in (mips*-*-irix[6789]*): Correction to m4 quoting of this
        pattern.  (Believe the mips64*-*-* part also used picks up all current
        irix6 tuples anyway.)  Reported by Rainer Orth.

2004-04-30  Kevin Ryde  <kevin@swox.se>

        * acinclude.m4 (GMP_PROG_CC_X86_GOT_EAX_EMITTED,
        GMP_ASM_X86_GOT_EAX_OK): New macros.
        (GMP_PROG_CC_WORKS): Use them to detect an old gas bug tickled by
        recent gcc.  Reported by David Newman.

        alternative to gmp_randinit.

2004-04-29  Torbjorn Granlund  <tege@swox.com>

        * configfsf.guess: Update to 2004-03-12.
        * configfsf.sub: Likewise.

2004-04-27  Torbjorn Granlund  <tege@swox.com>

        * mpz/rrandomb.c (gmp_rrandomb): Rework to avoid extra limb allocation
        and to generate even numbers.
        * mpn/generic/random2.c (gmp_rrandomb): Likewise.

2004-04-25  Kevin Ryde  <kevin@swox.se>

        * gmp-impl.h (FORCE_DOUBLE): Don't use an asm with a match constraint
        on a memory output, apparently not supported and provokes a warning
        from gcc 3.4.

2004-04-24  Kevin Ryde  <kevin@swox.se>

        * longlong.h (count_leading_zeros_gcc_clz,
        count_trailing_zeros_gcc_ctz): New macros.
        (count_leading_zeros, count_trailing_zeros) [x86]: Use them on gcc
        3.4.

        * configure.in (x86-*-* gcc_cflags_cpu): Give a -mtune at the start of
        each option list, for use by gcc 3.4 to avoid deprecation warnings
        about -mcpu.

        mpz/cfdiv_r_2exp.c, mpq/aors.c, mpf/ceilfloor.c: Give REGPARM_ATTR()
        on function definition too, as demanded by gcc 3.4.

2004-04-22  Kevin Ryde  <kevin@swox.se>

        * tests/rand/t-lc2exp.c (check_bigc1): New test.

        * doc/fdl.texi: Tweak @appendixsubsec -> @appendixsec to match our
        preference for this in an @appendix, and because texi2pdf doesn't
        support @appendixsubsec directly within an @appendix.

2004-04-20  Kevin Ryde  <kevin@swox.se>

        * doc/texinfo.tex: Update to 2004-04-07.08 from texinfo 4.7.
        * doc/gmp.texi, mpfr/mpfr.texi (@copying): Don't put a line break in
        @ref within @copying, recent texinfo.tex doesn't like that.

        * demos/perl/GMP.xs (static_functable): Treat cygwin the same as mingw
        DLLs.

        * */Makefile.in, install-sh: Update to automake 1.8.3.

        * acinclude.m4, configure.in (GMP_C_RIGHT_SHIFT): Remove, no longer
        needed.
        * tests/t-hightomask.c: New file.
        * tests/Makefile.am (check_PROGRAMS): Add it.

        * macos/configure (parse_top_configure): Look for PACKAGE_NAME and
        PACKAGE_VERSION now used by autoconf.
        (what_objects): Only demand 9 object files, as for instance occurs in
        the scanf directory.
        (asm files): Transform labels L(foo) -> Lfoo.  Take func name from
        PROLOGUE to support empty "EPILOGUE()".  Recognise and subsitute
        register name "define()"s.
        * macos/Makefile.in (CmnObjs): Add tal-notreent.o.

2004-04-19  Torbjorn Granlund  <tege@swox.com>

        * doc/fdl.texi: Update from FSF, just fixing a couple of typos.

        * macos/configure, macos/Makefile.in: Add printf and scanf directories.

        * tests/mpz/t-gcd.c (check_data): New function, exercising K6
        gcd_finda bug.

2004-04-14  Kevin Ryde  <kevin@swox.se>

        * doc/gmp.texi (Reentrancy, Random State Initialization): Note
        gmp_randinit use of gmp_errno is not thread safe.  Reported by Vincent
        Lefèvre.

        * doc/gmp.texi (Random State Initialization): Add index entries for
        gmp_errno and constants.

        * mpn/m68k/README: Update _SHORT_LIMB -> __GMP_SHORT_LIMB.

        * configure.in (--enable-mpbsd): Typo Berkley -> Berkeley in help msg.

2004-04-12  Kevin Ryde  <kevin@swox.se>

        * demos/perl/GMP.xs (static_functable): New macro, use it for all
        function tables, to support mingw DLL builds.
        * demos/perl/INSTALL (NOTES FOR PARTICULAR SYSTEMS): Remove note on
        DLLs, should be ok now.

        * demos/perl/sample.pl: Print the module and library versions in use.

        * demos/perl/GMP.pm, Makefile.PL (VERSION): Set to '2.00'.

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.
        (FORCE_DOUBLE): Use this for amd64 too.

        * tests/amd64check.c, tests/amd64call.asm: New files, derived in part
        from x86check.c and x86call.asm.
        * tests/Makefile.am (EXTRA_libtests_la_SOURCES): Add them.
        * configure.in (x86_64-*-* ABI=64): Use them.

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

        * mpn/amd64/mode1o.asm: New file.
        * mpn/amd64/amd64-defs.m4 (ASSERT): New macro.

        * doc/gmp.texi (Language Bindings): Add GOO, MLGMP and Numerix.

        * mpf/mul_2exp.c, mpf/div_2exp.c: Rate u==0 as UNLIKELY.

2004-03-27  Torbjorn Granlund  <tege@swox.com>

        * mpn/generic/divrem_1.c: Fix typo.

        * mpn/generic/sqr_basecase.c: Fix typo.

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.

        * mpn/generic/sqr_basecase.c: Add versions using mpn_addmul_2 and
        mpn_addmul_2s.

2004-03-14  Kevin Ryde  <kevin@swox.se>

        * mpf/mul_ui.c: Incorporate carry from low limbs, for exactness.
        * 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/t-div.c: New file.
        * 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/mpf/t-ui_div.c (check_rand): Exercise r==v overlap.

        * 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/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.

2004-03-01  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

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.

        * mpn/generic/mul_n.c (mpn_toom3_sqr_n): Remove write-only variable c5.

2004-02-18  Kevin Ryde  <kevin@swox.se>

        * mpf/iset_si.c, mpf/iset_ui.c, mpf/set_si.c, mpf/set_ui.c [nails]:
        Always store second limb, to avoid a conditional.

        * tests/mpf/t-get_ui.c: New file.
        * tests/mpf/Makefile.am (check_PROGRAMS): Add it.
        * tests/mpf/t-get_si.c (check_limbdata): Further tests.
        * 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.

2004-02-11  Kevin Ryde  <kevin@swox.se>

        * longlong.h (power, powerpc): Use HAVE_HOST_CPU_FAMILY_power and
        HAVE_HOST_CPU_FAMILY_powerpc rather than various cpp defines.

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

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

        * tests/refmpf.c, tests/tests.h (refmpf_add_ulp,
        refmpf_set_prec_limbs): New functions.

        * 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,
        -march=k8.
        (amd64-*-*): Remove pattern, config.sub only gives x86_64.
        * doc/gmp.texi (ABI and ISA): Add x86_64 dual ABIs.

        * gmp-h.in (_GMP_H_HAVE_FILE): Add _MSL_STDIO_H for Metrowerks.
        Reported by Tomas Zahradnicky.

2004-01-16  Kevin Ryde  <kevin@swox.se>

        * configure.in (powerpc64-*-linux*): Try gcc64.  Try -m64 with
        "cflags_maybe" to get it used in all probing.  Add sizeof-long-8 test
        to check the mode is right if -m64 is not applicable.

2004-01-15  Kevin Ryde  <kevin@swox.se>

        * configure.in (--with-readline=detect): Check for readline/readline.h

        (m4_assert_defined): Use it.

        * mpn/alpha/default.m4, mpn/alpha/unicos.m4 (LDGP): New macro.
        * mpn/alpha/ev67/gcd_1.asm: Use it to re-establish gp after jsr.

        * configure.in, demos/calc/Makefile.am: Use -lcurses or -lncurses with
        readline, when available.

        * longlong.h (sub_ddmmss) [generic]: Use al<bl for the borrow rather
        than __x>al, since the former can be done without waiting for __x,
        helping superscalar chips, in particular alpha ev5 and ev6.

        * longlong.h (sub_ddmmss) [ia64]: New macro.

        * tests/t-sub.c: New file.

        keep in our namespace.  (Not actually used anywhere currently.)
        Reported by Patrick Pelissier.

        * mp-h.in: Use "! defined (__GMP_WITHIN_CONFIGURE)" in the same style
        as gmp-h.in (though mp-h.in is not actually used during configure).

        * mp-h.in (__GMP_DECLSPEC_EXPORT, __GMP_DECLSPEC_IMPORT) [__GNUC__]:
        Use __dllexport__ and __dllimport__ to keep out of application

        * doc/gmp.texi (Integer Logic and Bit Fiddling): Say "bitwise" in

        longer demands HOST_CC.

        systems not using names libgmp.so.*.

        * tests/devel/try.c (try_one): When overlapping, copy source data
        after filling dst.  Previously probably used only DEADVAL in
        overlapping cases.

        (cmov_available_p, psadbw_available_p): Remove.
        This trickery was only ever for development purposes on machines
        without those instructions.  Removing it simplifies gmp and in
        particular avoids complications for fat binary builds.  Development
        can be done with a wrapper around "as" if really needed.

        * mpn/x86/divrem_1.asm: Don't use loop_or_decljnz, now K6 has its own
        mpn/x86/k6/divrem_1.asm.  Amend K6 comments now moved to there.

        since the code is a bit too big.  gcc doesn't actually inline when
        alloca (TMP_ALLOC) is used anyway.

2003-05-13  Kevin Ryde  <kevin@swox.se>

        * gmp.texi (Notes for Particular Systems): Libtool directory is .libs

        applications using gcc -Wundef.

        * longlong.h: Define COUNT_LEADING_ZEROS_NEED_CLZ_TAB for all alphas,

        * gmp-impl.h (MUL_FFT_THRESHOLD, SQR_FFT_THRESHOLD): Note
        mpn/generic/mul_fft.c is not nails-capable, and don't bother setting
        other FFT data for nails.

        * configfsf.guess: Update to 2002-08-19.
        * configfsf.sub: Update to 2002-08-20.

        reported by Jason Moxham.  Exclude x==n-1, ie. -1 mod n.  Use

        * 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_*.

        * 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.

        * 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.)
