*	[LoopUnrolling] Fix a bug introduced in r259869 (PR26688).	Michael Zolotukhin	2016-02-22	1	-0/+34
\| \| \| \| \| \| \| \|	The issue was that we only required LCSSA rebuilding if the immediate parent-loop had values used outside of it. The fix is to enaable the same logic for all outer loops, not only immediate parent. llvm-svn: 261575
*	Don't recompute LCSSA after loop-unrolling when possible.	Michael Zolotukhin	2015-11-14	1	-0/+119
	Summary: Currently we always recompute LCSSA for outer loops after unrolling an inner loop. That leads to compile time problem when we have big loop nests, and we can solve it by avoiding unnecessary work. For instance, if w eonly do partial unrolling, we don't break LCSSA, so we don't need to rebuild it. Also, if all exits from the inner loop are inside the enclosing loop, then complete unrolling won't break LCSSA either. I replaced unconditional LCSSA recomputation with conditional recomputation + unconditional assert and added several tests, which were failing when I experimented with it. Soon I plan to follow up with a similar patch for recalculation of dominators tree.
