* * Commit the fix (by Chris) for a tblgen type inferencing bug.Evan Cheng2005-12-044-71/+198
| | | | | | | | | | | | * Enhanced tblgen to handle instructions which have chain operand and writes a chain result. * Enhanced tblgen to handle instructions which produces no results. Part of the change is a temporary hack which relies on instruction property (e.g. isReturn, isBranch). The proper fix would be to change the .td syntax to separate results dag from ops dag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24587 91177308-0d34-0410-b5e6-96231b3b80d8
