Evan Cheng e41bf82107 Allow more loads to be folded which were previously prevented from happening ... due to ordering issue. i.e. they were selected for chain use first. Now at load select time, check if it is being selected for a chain use and if it has only a single real use. If so, return a HANDLENODE (with the load as its operand) in its place and record it. When it is folded or the load is selected for a real use, the isel records it as the replacement for the HANDLENODE. The replacement is done when all nodes are selected. This scheme exposed a couple of problems where cycles can happen. (See comments in EmitMatchCode() for descriptions of the problems and their workaround / solutions.) These problems have been resolved with a small compile time penality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25995 91177308-0d34-0410-b5e6-96231b3b80d8		2006-02-05 06:43:12 +00:00
