Arguably there should be some general mechanism, but there isn't yet,
and I hit a build failure at
cp ${.CURDIR}/arch/${GMP_MACHINE_ARCH}/config.m4 ${.OBJDIR}/config.m4
because my source tree is mode 444, and hence my previously-copied
config.m4 was too.
- Bug fixes (see <http://www.mpfr.org/mpfr-3.1.1/#fixed> or ChangeLog file).
- Bug fixes (see <http://www.mpfr.org/mpfr-3.1.0/#fixed> or ChangeLog file).
- TLS support is now detected automatically. If TLS is supported, MPFR is
built as thread safe by default. To disable TLS explicitly, configure
MPFR with --disable-thread-safe.
- The mpfr_urandom and mpfr_urandomb functions now return identical values
on processors with different word size (assuming the same random seed, and
since the GMP random generator does not depend itself on the word size,
cf http://gmplib.org/list-archives/gmp-devel/2010-September/001642.html).
- The mpfr_add_one_ulp and mpfr_sub_one_ulp macros (which are obsolete and
no more documented) will be removed in a future release.
- Speed improvement for the mpfr_sqr and mpfr_div functions using Mulders'
algorithm. As a consequence, other functions using those routines are
also faster.
- Much faster formatted output (mpfr_printf, etc.) with %Rg and similar.
- New functions mpfr_buildopt_gmpinternals_p, mpfr_buildopt_tune_case,
mpfr_frexp, mpfr_grandom and mpfr_z_sub.
- New divide-by-zero exception (flag) and associated functions.
- Internal change: the logging mechanism has been improved.
- Bug fixes, in particular a huge inefficiency in mpfr_exp (when the
target precision is less than MPFR_EXP_THRESHOLD) on hard-to-round
cases, which can take several minutes.
Changes in version 1.0.1:
- Switched to automake 1.11.6, see
https://lists.gnu.org/archive/html/automake/2012-07/msg00023.html
- #14669: Fixed extraction of CC from gmp.h
- Fixed case of intermediate zero real or imaginary part in mpc_fma,
found by hydra with GMP_CHECK_RANDOMIZE=1346362345
Changes in version 1.0:
- First release as a GNU package
- License change: LGPLv3+ for code, GFDLv1.3+ (with no invariant sections)
for documentation
- 100% of all lines are covered by tests
- Functions renamed:
mpc_mul_2exp to mpc_mul_2ui, mpc_div_2exp to mpc_div_2ui
- 0^0, which returned (NaN,NaN) previously, now returns (1,+0)
- Removed compatibility with K&R compilers, untestable due to lack of
such compilers
- New functions: mpc_log10, mpc_mul_2si, mpc_div_2si
- Speed-ups:
- mpc_fma
- Bug fixes:
- mpc_div and mpc_norm now return a value indicating the effective
rounding direction, as the other functions
- mpc_mul, mpc_sqr and mpc_norm now return correct results even if there
are over- or underflows during the computation
- mpc_asin, mpc_proj, mpc_sqr: Wrong result when input variable has
infinite part and equals output variable is corrected
- mpc_fr_sub: Wrong return value for imaginary part is corrected
