Implicitly defined virtual registers can simply have the <undef> bit set on all uses, and copies can be turned into implicit defs recursively. Physical registers are a bit trickier. We handle the common case where a physreg def is used by a nearby instruction in the same basic block. For more complicated cases, just leave the IMPLICIT_DEF instruction in. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159149 91177308-0d34-0410-b5e6-96231b3b80d8
