it impossible to create a MERGE_VALUES node with only one result: sometimes it is useful to be able to create a node with only one result out of one of the results of a node with more than one result, for example because the new node will eventually be used to replace a one-result node using ReplaceAllUsesWith, cf X86TargetLowering::ExpandFP_TO_SINT. On the other hand, most users of MERGE_VALUES don't need this and for them the optimization was valuable. So add a new utility method getMergeValues for creating MERGE_VALUES nodes which by default performs the optimization. Change almost everywhere to use getMergeValues (and tidy some stuff up at the same time). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52893 91177308-0d34-0410-b5e6-96231b3b80d8 |
