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 splitting at each use points increases the number of live ranges that could be performance bottleneck. Split partner ...
Unaligned memory access in vectorization For misaligned array access inside the loops for aligned architecture, vectorization ...
Register Allocation on SSA Graphs. The SSA graph has the property that def dominates uses. This makes the SSA graph strict. ...
Live range splitting optimization. There is an important concept above the Live range splitting. If the interference graph ...
