* config.guess (powerpc*-*-*): Add more processor types to mfpvr code.
* configure.in: Generalize powerpc subtype matching code.
* mpz/fac_ui.c: Misc cleanups, spelling corrections.
2004-05-14 Kevin Ryde <kevin@swox.se>
* mpf/sub.c: When one operand cancels high limbs of the other, strip
high zeros on the balance before truncating to destination precision.
Truncating first loses accuracy and can lead to a result 0 despite
operands being not equal. Reported by John Abbott.
Also, ensure exponent is zero when result is zero, for instance if
operands are exactly equal.
* tests/mpf/t-sub.c (check_data): New function, exercising these.
2004-05-12 Kevin Ryde <kevin@swox.se>

workaround an automake bug.
2004-05-10 Kevin Ryde <kevin@swox.se>

mpf_init2 to follow requested precision.
* demos/expr/exprza.c, demos/expr/exprqa.c: Use wrappers for mpX_init,
to make parameters match.
* demos/expr/run-expr.c: Don't use getopt, to avoid needing configury
for optarg declaration. Remove TRY macro, rename foo and bar to var_a
and var_b, for clarity.
* demos/expr/expr-impl.h: Don't use expr-config.h.
* configure.in (demos/expr/expr-config.h): Remove.
* demos/expr/expr-config.in: Remove file.
2004-05-08 Kevin Ryde <kevin@swox.se>

demos/expr/expr.c, demos/expr/expr.h, demos/expr/expr-config-h.in,
demos/expr/expr-impl.h, demos/expr/run-expr.c, demos/expr/t-expr.c:
MPFR now published separately, remove various bits.
* mpfr/*, tests/cxx/t-headfr.cc, demos/expr/exprfr.c,
demos/expr/exprfra.c: Remove.
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.

* tune/tuneup.c (tune_mullow): New function.
* gmp-impl.h (invert_limb): Compute branch-freely.
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.

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/aorsmul.c, mpz/aorsmul_i.c, mpz/cfdiv_q_2exp.c,
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.

DLLs.
* */Makefile.in, install-sh: Update to automake 1.8.3.
* ltmain.sh, aclocal.m4, configure: Update to libtool 1.5.6.
* gmp-impl.h (LIMB_HIGHBIT_TO_MASK): Use a compile-time constant
expression, rather than a configure test.
* 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.

PROLOGUE to support empty "EPILOGUE()". Recognise and substitute
register name "define()"s.
* macos/Makefile.in (CmnObjs): Add tal-notreent.o.

gcd_finda bug.
2004-04-14 Kevin Ryde <kevin@swox.se>
* doc/gmp.texi (Reentrancy, Random State Initialization): Note

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>

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.

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>
* mpn/x86/fat/fat.c (__gmpn_cpuvec_init, fake_cpuid_table): Add x86_64.
* mpq/get_d.c: Use mpn_tdiv_qr, demand den>0 per canonical form.
2004-03-16 Torbjorn Granlund <tege@swox.com>
* 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/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.
