There are a few steps to this process. 1) It takes allocations of aggregates and analyzes the ways in which they are used to try to split them into smaller allocations, ideally of a single scalar data type. It will split up memcpy and memset accesses as necessary and try to isolate individual scalar accesses. WebScalar Replacement of Aggregates Why? Compiler may limit optimization to such scalars Can do better register allocation, constant propagation,... Ex. type complex C.real := ... C.imaj real: T1 := ...

A tabled-valued function returns your specified columns for rows in your table meeting your selection criteria. An aggregate-valued function returns a calculation across the rows of a table -- for example summing values. Share Improve this answer WebScalar replacement of aggregates means replacing an object allocated on the heap (for example, Point p = new Point) by local variables corresponding to its fields (double x, double y) Removing the object allocation saves time and puts less pressure on the GC.
