[TODO] Updated item on tzeta:
* removed the old problem: the fact that the traces for the trunk and for r9954 are different is normal (fixes in mpfr_can_round affecting tgeneric.c), and the timings depend on GMP_CHECK_RANDOMIZE and seem equivalent in average with "test_generic (..., 5);" in both cases; * added the fact that tzeta has been much slower since r9848, at least with the x86 32-bit ABI. git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@10789 280ebfd0-de03-0410-8827-d642c229c3f4

(The one done in r10573 allowed us to find a bug even without
assertion checking.)
-- after the fix of mpfr_can_round in r9883, tzeta has a different trace
- from r9882, which may be expected as mpfr_can_round has an influence
- in tgeneric.c, but a closer look is needed: check only the first
- difference (with various GMP_CHECK_RANDOMIZE values), since after it,
- the random numbers do not match.
- With the 32-bit ABI, tzeta r9955 is even 2.17 times as slow as r9954;
- the corresponding change:
- - test_generic (2, 70, 5);
- + test_generic (MPFR_PREC_MIN, 70, 5);
- Find the real cause, whether a wrong result could be obtained before
- the fix r9883, and whether the slowdown can be avoided.
+- tzeta has been much slower due to r9848, at least with the x86 32-bit ABI;
+ see whether this was expected.
