a header file from libcodegen. This violates a layering order: codegen depends on target, not the other way around. The fix to this is to split TII into two classes, TII and TargetInstrInfoImpl, which defines stuff that depends on libcodegen. It is defined in libcodegen, where the base is not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45475 91177308-0d34-0410-b5e6-96231b3b80d8
