14<h1> ChangeLog </h1>
15<h2> trunk</h2>
16
17<ul>
18<li>Optimized isl for small integers, such that mostly cheap 32bit operations
19are used instead of costly arbitrary precision integers that often also involve
20malloc/free calls. As a result, the compile-time increase due to Polly has
21been largely reduced.</li>
22
23<li>Support for modulo operations: Accesses such as <pre>A[t%2][i]</pre> can
24    now be analyzed.
25</ul>
26
27<h2> 3.7 </h2>
28
29<ul>
30<li>libPluto support has been removed. It has not been tested regularly and
31due to it being copyleft license it had never a chance to become a a core
32piece of Polly. Experiments with different schedulers should use the jscop
33interface.</li>
34</ul>
35
36<h2> 3.6</h2>
37
38<ul>
39<li>Switch to the new isl AST generator (replacing CLooG)</li>
40<li>Run-time alias checks</li>
41<li>Computation of no-alias information for later LLVM optimizations
42(vectorizer, LICM, ...)</li>
43<li>Support for multi-dimensional arrays of parameteric size (still tested)</li>
44<li>New assumption tracking framework</li>
45<ul>
46<li>Accesses to multi-dimensional arrays of fixed size are within bounds</li>
47</ul>
48<li>Compile-time reduction</li>
49</ul>
