/mpfr, GMP-based library for multiple-precision floating-point computations
3.1.5, Package name:
mpfr-3.1.5, Maintainer: pkgsrc-users
The MPFR library is a C library for multiple-precision floating-point
computations with exact rounding (also called correct rounding). It is
based on the GMP multiple-precision library and should replace the MPF
class in further releases of GMP.
The main goal of MPFR is to provide a library for multiple-precision
floating-point computation which is both efficient and has a well-defined
semantics. It copies the good ideas from the ANSI/IEEE-754 standard for
double-precision floating-point arithmetic (53-bit mantissa).

Don't clean intermediate files after checksum/patch phase.
The work directories are almost empty, so it doesn't save much space.
It makes debugging annoying and it breaks local DISTDIR settings.

Apply 11 upstream patches, bump to 3.2.1pl11.
Requested by Kai-Uwe Eckhardt.
Remove an incorrect comment.
One of the mpfr_exp implementations uses a left shift on an integer
that can be negative: exps <<= 1; and this has an undefined behavior
according to the ISO C standard. In most cases, this will correspond
to a multiplication by 2, and the code will behave as expected
(this is why the bug hadn't been detected until now). But problems
may occur if a sanitizer is used (this is how this bug was detected)
or possibly in case of advanced optimizations, such as LTO. This
is fixed by the exp_2 patch.
The mpfr_fits_u*_p functions return 0 ("doesn't fit") instead of
non-zero ("fits") on negative arguments for which the rounding to
an integer in the given rounding mode is 0. This bug is fixed by
the fits-smallneg patch, which also updates the testcases.
Some tget_flt tests fail in environments where native C floating-point
division by zero is not supported, e.g. regarded as an error, such
as with Clang's sanitizer; some similar tests were already disabled
in such a case, but not all. The tset_ld test triggers a useless
overflow on a double. These problems are fixed by the clang-divby0
patch, which also disables constant division by zero on the native
C type double with Clang in order to avoid incorrect code.
The formatted output functions (mpfr_*printf) are incorrect on the
value 0 when using the alternative form (# flag), a positive
precision, and the g or G conversion specifier: there is one
additional trailing 0. The corresponding test is also incorrect
(explaining why the bug was not detected). These problems are fixed
by the printf-alt0 patch, which also provides some additional
Only for applications using the custom interface: The mpfr_custom_init_set
macro has a typo in a variable name, which can yield incorrect
behavior if the second argument is not a simple expression. This
bug is fixed by the custom_init_set patch.
The build fails on li2.c with the GCC -Werror=return-type option
when logging has been enabled. This problem is fixed by the li2-return
The rounding of mpfr_exp can be incorrect for output precisions
larger than or equal to MPFR_EXP_THRESHOLD (several thousands of
bits; its value depends on the architecture). This bug is fixed by
the exp3 patch, which also provides a testcase.
This MPFR release fails to build with GMP 6 when the --with-gmp-build
configure option is used. The gmp6-compat patch fixes this
When dividing a very large number (near the maximum finite one, in
absolute value) by a very small number (near the minimum one, in
absolute value), an integer overflow occurs in the computation of
the exponent of the result, yielding undefined behavior, such as
the result 0 instead of infinity. This bug is fixed by the div-overflow
patch, which also provides a testcase.
The vasprintf.c source file contains incorrect assertions, which
may fail while the computation is valid; this can occur only when
outputting tiny numbers (very small exponents). These assertions
are fixed by the vasprintf patch, which also provides a testcase.
A buffer overflow may occur in mpfr_strtofr. This is due to incorrect
GMP documentation for mpn_set_str about the size of a buffer
(discussion; first fix in the GMP documentation). This bug is
present in the MPFR versions from 2.1.0 (adding mpfr_strtofr) to
this one, and can be detected by running "make check" in a 32-bit
ABI under GNU/Linux with alloca disabled (this is currently possible
by using the --with-gmp-build configure option where alloca has
been disabled in the GMP build). It is fixed by the strtofr patch.
