There may be bugs in some cases, but the casts fix the symptom, not the bug (unless one casts the unsigned type to a signed type that is *strictly* larger, which is not possible here). git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@5690 280ebfd0-de03-0410-8827-d642c229c3f4

* For the terminating null pointer of the functions mpfr_inits,vlefevre2008-02-151-1/+1
| | | | | | | | | | | | | | | | mpfr_inits2, mpfr_clears, always use the type mpfr_ptr (no longer void *). Updated the description of these functions in the manual (mpfr.texi). The reason is that the C standard does not guarantee that (void *) 0 has the same representation as a null pointer to a structure (and even the same size). In most C implementations, the representations are the same, but one never knows (dynamical checking is also always possible)... The change has been done with: perl -pi -e \ 's/(mpfr_(clear|init)s.*)\(void *\*\) *0\)/$1(mpfr_ptr) 0)/' **/*.c under zsh. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@5290 280ebfd0-de03-0410-8827-d642c229c3f4

* Merged the feature-block branch to the trunk:vlefevre2007-12-181-35/+42
| | | | | | | | | | | | | | | * New MPFR_BLOCK* macros (see mpfr-impl.h) and mpfrlint check to test exception flags in a more reliable way and detect possible problems with mpfrlint. * Improved the generic tests (tests/tgeneric.c): for the second function call, sometimes set all the flags since risk of failures are known when some flags are already set. * Modified code to use these new MPFR_BLOCK* macros. This fixed bugs related to exceptions (where flags are set before the call); in particular, tcot and ty1 failed with the improved generic tests. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@5115 280ebfd0-de03-0410-8827-d642c229c3f4
