Jakob Stoklund Olesen d135f14f61 Fix PR6283. ... When coalescing with a physreg, remember to add imp-def and imp-kill when dealing with sub-registers. Also fix a related bug in VirtRegRewriter where substitutePhysReg may reallocate the operand list on an instruction and invalidate the reg_iterator. This can happen when a register is mentioned twice on the same instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96072 91177308-0d34-0410-b5e6-96231b3b80d8		2010-02-13 02:06:10 +00:00
