| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * acinclude.m4: - test $enable_shared_cache instead of $mpfr_want_shared_cache; - check ISO C11 thread support and/or POSIX thread support only when necessary; - when checking support for POSIX threads (pthread), also check that pthread_rwlock_t is supported, as it is needed by MPFR and conditionally defined in glibc's bits/pthreadtypes.h (via <pthread.h>); - with POSIX threads, also set CC="$PTHREAD_CC" as documented by ax_pthread (autoconf-archive). This is not guaranteed to work, but according to the ax_pthread.m4 source, in the cases where "$PTHREAD_CC" != "$CC", not setting it will probably not work either; - handle --enable-shared-cache early in MPFR_CONFIGS, because the use of POSIX threads (pthread) may need to change CC, CFLAGS, and LIBS (thus affecting other tests); - removed the now useless MPFR_CHECK_SHARED_CACHE function. * configure.ac: no longer set the mpfr_want_shared_cache variable, as enable_shared_cache (now used) already has the same usage. * acinclude.m4, configure.ac: moved the compatibility test of the configure options even earlier, from acinclude.m4 to configure.ac, just after the code that defines them. Also added an associated AC_MSG_CHECKING message for better clarity. * src/mpfr-impl.h: added a comment about the cache-related types, which depend on the locking methods. * src/mpfr-thread.h: fixed the lock macros: - in case of failure, one must abort, otherwise this would generally be undefined behavior; - added missing "do {} while (0)" (currently not mandatory). * tests/tversion.c: update concerning the shared cache, to be consistent with the other mpfr_buildopt_*_p features: - check that mpfr_buildopt_sharedcache_p() and MPFR_WANT_SHARED_CACHE match; - for the output of the value, test mpfr_buildopt_sharedcache_p() instead of the macro. * NEWS: update.

Also adapted the code to work with small-size limbs. [tests/tstrtofr.c] Added tests, including random tests. In particular, some part of the code was tested only on hard-to-round cases, meaning that some potential issues could not be detected (intermediate results were thrown out due to the next Ziv iteration). Moreover, in case of failure of some particular test, output the probable cause of this failure (GCC bug 86554) with a workaround. (merged changesets associated with these files r12566-13306,13364-13365 from the trunk) Note: There may still remain issues with mpfr_strtofr, to be checked later.
