* Merged the feature-block branch to the trunk:vlefevre2007-12-181-4/+5
| | | | | | | | | | | | | | | * 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

| | | | | | | | | | | some very small positive arguments too); this bug is similar to the one in log1p that was recently found and fixed. It was detected by the new generic tests (not committed yet), therefore no testcases are provided. Note: the mpfr_expm1 function is still buggy (freezes on -0.10E18, prec 2 -> prec 13); this is a different bug. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@4125 280ebfd0-de03-0410-8827-d642c229c3f4
