R110 can have the value -1 (BB6, BB7, BB8) or 0 (BB5). Thus there is no single

Does the value of R110 should not change across all the callee path from the
given caller functions. If the value is aliased, then how the call side
affects should make
sure the value remains same across all the callee chain path from the given
caller function. I am curious to know how the value remain constant throughout
the function
is identified in case of aliasing and the interprocedural case.
Pseudo registers are allowed to have aliases.
