Richard Sandiford 55d7d83b6c [SystemZ] Use upper words of GR64s for codegen ... This just adds the basics necessary for allocating the upper words to virtual registers (move, load and store). The move support is parameterised in a way that makes it easy to handle zero extensions, but the associated zero-extend patterns are added by a later patch. The easiest way of testing this seemed to be add a new "h" register constraint for high words. I don't expect the constraint to be useful in real inline asms, but it should work, so I didn't try to hide it behind an option. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191739 91177308-0d34-0410-b5e6-96231b3b80d8		2013-10-01 11:26:28 +00:00
