Cameron Zwarich	e924969380	Address most of Duncan's review comments. Also, make LoopInstSimplify a simple ... FunctionPass. It probably doesn't have a reason to be a LoopPass, as it will probably drop the simple fixed point and either use RPO iteration or Duncan's approach in instsimplify of only revisiting instructions that have changed. The next step is to preserve LoopSimplify. This looks like it won't be too hard, although the pass manager doesn't actually seem to respect when non-loop passes claim to preserve LCSSA or LoopSimplify. This will have to be fixed. llvm-svn: 122791	2011-01-04 00:12:46 +00:00
Cameron Zwarich	cab9a0abab	Add a new loop-instsimplify pass, with the intention of replacing the instance ... of instcombine that is currently in the middle of the loop pass pipeline. This commit only checks in the pass; it will hopefully be enabled by default later. llvm-svn: 122719	2011-01-03 00:25:16 +00:00
