New minor version
{{{
Changes from versions 4.0.* to version 4.1.0:
- The "épinards à la crème" release.
- Binary compatible with MPFR 4.0.*, though some minor changes in the
behavior of the formatted output functions may be visible, regarded
as underspecified behavior or bug fixes (see below).
- New --enable-formally-proven-code configure option, to use (when
available)
formally proven code.
- Improved __GMP_CC and __GMP_CFLAGS retrieval (in particular for MS
Windows).
- Option -pedantic is now always removed from __GMP_CFLAGS (see INSTALL).
- Changed __float128 to the type _Float128 specified in ISO/IEC TS 18661.
__float128 is used as a fallback if _Float128 is not supported.
- New function mpfr_get_str_ndigits about conversion to a string of
digits.
- New function mpfr_dot for the dot product (incomplete, experimental).
- New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available
only
when MPFR has been built with decimal float support).
- New function mpfr_cmpabs_ui.
- New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
- The mpfr_out_str function now accepts bases from -2 to -36, in order to
follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
assertion failure, as with other invalid bases).
- Shared caches: cleanup; really detect lock failures (abort in this
case).
- The behavior of the formatted output functions (mpfr_printf, etc.) with
an empty precision field has improved: trailing zeros are kept in a way
similar to the formatted output functions from C.
- Improved mpfr_add and mpfr_sub when all operands have a precision equal
to
twice the number of bits per word, e.g., 128 bits on a 64-bit platform.
- Optimized the tuning parameters for various architectures.
- Improved test coverage to 98.6% of code for x86_64.
- Bug fixes.
- MPFR manual: corrected/completed the mpfr_get_str description in order
to
follow the historical behavior and GMP's mpf_get_str function.
- New: optional "make check-exported-symbols", mainly for the MPFR
developers
and binary distributions, to check that MPFR does not define symbols
with a
GMP reserved prefix (experimental).
- Mini-gmp support: replaced --enable-mini-gmp configure option by
--with-mini-gmp (still experimental, read doc/mini-gmp).
- A GCC bug on Sparc (present at least in old GCC 4.5.3 and 5.5.0
versions),
which made several tests fail when TLS was enabled, is now avoided in
the
tests. The MPFR library itself was not affected and normal code using
the
MPFR library should not be affected either. Users and distributions that
disabled TLS just because of the test failures can safely re-enable it.
