* [acinclude.m4,configure.ac] Check the support of the group flag forvlefevre2018-07-271-0/+25
| | | | | | | | native integers, which is a Single UNIX Specification extension. [tests/tsprintf.c] Test the group flag with the P length modifier only when supported, since the implementation relies on this support. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@12964 280ebfd0-de03-0410-8827-d642c229c3f4
* Shared caches: fix and minor changes.vlefevre2018-07-181-1/+1
| | | | | | | | | | | | | | * Fixed detection and use of C11 thread support: the C11 header is <threads.h>, not <thread.h>. * Renamed WANT_SHARED_CACHE to MPFR_WANT_SHARED_CACHE for consistency with the other MPFR_WANT_* macros. * Added MPFR_THREAD_LOCK_METHOD macro, giving the thread locking method as a string (when shared caches are enabled). * doc/README.dev: documented 4 macros for shared caches. * tests/tversion.c: output MPFR_WANT_SHARED_CACHE and MPFR_THREAD_LOCK_METHOD information. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@12937 280ebfd0-de03-0410-8827-d642c229c3f4

* Updated support for binary128:vlefevre2018-02-261-7/+19
| | | | | | | | | | | | | | | | | | | | | | * __float128 was changed to _Float128 (ISO/IEC TS 18661) in r12391; also changed the suffix of the constants from "q" to "f128". * Use __float128 with the "q" suffix as a fallback in order to avoid regressions with GCC 6- and with C++ mode (g++). As documented in the GCC manual, this is entirely compatible on most platforms where both are supported: _Float128 and __float128 are the same type, and it could be checked that the following prototypes are equivalent (as expected): _Float128 f (__float128) __float128 f (_Float128) The only potential issues would be on hppa and IA-64 HP-UX, where __float128 is an alias for "long double" instead of _Float128, in case the ABI would be different (I have no information about this) and both would be mixed up with software using the MPFR conversion functions for binary128 via __float128 or "long double". The worst thing that could happen is a link error. If the link is accepted, everything should be fine as the representation doesn't change. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@12444 280ebfd0-de03-0410-8827-d642c229c3f4
