I have confirmed via manual inspection and the use of a dynamic analysis tool that the next use of the R11 def in s1578 is s1725.
Could you please clarify these two points?
Thanks,
Scott

Hi Scott,
That #1073741833 is a register mask. They are treated as aggregate registers (essentially sets of registers), so if it includes R9D and R11D, it will be treated as being aliased with both.
These separate defs are there because they reach disjoint registers.
