 By default, the transformation applies partial loop unrolling, resulting in two loops:
-- The first loop is the partially unrolled loop, processing multiple iterations per pass.
+* The first loop is the partially unrolled loop, processing multiple iterations per pass. -
-- The second loop handles any remaining iterations that do not fit into the unroll factor (cleanup loop).
+* The second loop handles any remaining iterations that do not fit into the unroll factor (cleanup loop).
 emmtrix Studio attempts to calculate a trip count that enables two key optimizations:
-. Full unrolling is applied if the unroll factor is greater than or equal to the trip count.
+* Full unrolling is applied if the unroll factor is greater than or equal to the trip count.
-. The cleanup loop is omitted if the trip count is exactly divisible by the unroll factor.
+* The cleanup loop is omitted if the trip count is exactly divisible by the unroll factor.
