If your program is very complex, or if there are too many computations to hold in registers at one time and your program needs temporary storage, you might need to increase this area. Do not enlarge the spill area unless the compiler issues a message requesting a larger spill area. In case of a conflict, the largest spill area specified is used.


If you received a warning message when compiling myprogram.c and want to compile it specifying a spill area of 900 entries, enter:

xlc myprogram.c -qspill=900
