1 ====== Libfirm 1.13.0 (XXXX-XX-XX) ======
3 * VanDrunen's GVN-PRE fixed
4 * operator strength reduce fixed and improved
5 * fixed 64bit code generation for some rary compare cases
6 * better tailrecursion optimization: handles x * func() and x + func()

9 * lowering of CopyB nodes
10 * better memory disambiguator
11 * float->64bit conversion fixed for x87
12 * removed old verbosity level based debugging: all modules use the new debug facility
