Evan Cheng 966fd37ba5 1) With X86 lowering change, the following can no longer happen since ... the branch's chain is also produced by cmp. [ch, r : ld] ^ ^ | | [XX]--/ \- [flag : cmp] ^ ^ | | \---[br flag]- Remove an isel check which prevents loads from being folded into cmp / test instructions. 2) Whenever possible, delete a selected node to allow more load folding opportunities. Note not all nodes can be deleted after it has been selected. Some may have simply morphed; some have not changed at all (e.g. EntryToken). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30242 91177308-0d34-0410-b5e6-96231b3b80d8		2006-09-11 02:24:43 +00:00
