Hi
        My question was abt how register allocation affected induction
variables which
are globals. My question is based on what I found with even small
programs. The induction variable value seemed to be always loaded from
memory. This was with a gcc cross compiler for MCORE. So is there any
thing in the register allocation which prevents them being allocated
into registers ?
