Jakob Stoklund Olesen 0a65533a38 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. llvm-svn: 96072		2010-02-13 02:06:10 +00:00
