This isn't right, at least not without other changes. This prevents
using references where the register is set as
Hi,
We use loop induction variable analysis to find count_reg.
Without doloop optimization, count_reg might be a READ_WRITE_REG.
E.g. while (reg < 0x200) { MEM [++reg:SI] = 5}
READ_WRITE_REG won't identify as loop induction variable
and SMS will skip the loop. We modify loop-iv.c to identify th
