Code Compaction optimizations: Optimizations strategies for code compaction that are spec'ed out. a) Loop Rereolling in straight line code. In this optimization isomorphic ...

Four live ranges L1/L2/L3/L4. Live range L1 for variable ‘a’ spans the loop but has no references ‘a’ inside the Loop. similarly, live range L2 for variable ‘b’ spans the loop but has ...

Live range splitting at each use points increases the number of live ranges that could be performance bottleneck. Split partner ranges could be assigned different registers increasing more ...
