Allow TableGen DAG arguments to be just a name.
DAG arguments can optionally be named: (dag node, node:$name) With this change, the node is also optional: (dag node, node:$name, $name) The missing node is treated as an UnsetInit, so the above is equivalent to: (dag node, node:$name, ?:$name) This syntax is useful in output patterns where we currently require the types of variables to be repeated: def : Pat<(subc i32:$b, i32:$c), (SUBCCrr i32:$b, i32:$c)>; This is preferable: def : Pat<(subc i32:$b, i32:$c), (SUBCCrr $b, $c)>; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177843 91177308-0d34-0410-b5e6-96231b3b80d8
