  14 <h1> ChangeLog </h1>
  15 <h2> trunk</h2>
  16
  17 <ul>
  18 <li>Optimized isl for small integers, such that mostly cheap 32bit operations
  19 are used instead of costly arbitrary precision integers that often also involve
  20 malloc/free calls. As a result, the compile-time increase due to Polly has
  21 been 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
  31 due to it being copyleft license it had never a chance to become a a core
  32 piece of Polly. Experiments with different schedulers should use the jscop
  33 interface.</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>
