Jakob Stoklund Olesen b09701db9e Correctly handle <undef> tied uses when rewriting after a split. ... This fixes PR10463. A two-address instruction with an <undef> use operand was incorrectly rewritten so the def and use no longer used the same register, violating the tie constraint. Fix this by always rewriting <undef> operands with the register a def operand would use. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135885 91177308-0d34-0410-b5e6-96231b3b80d8		2011-07-24 20:23:50 +00:00
