| Option Type | Default Value | #pragma options | C | C++ |
| -qoption | spill=512 | SPILL=size | x | x |
Syntax
-qspill=size
SPILL=size
Purpose
Specifies the register allocation spill area as being size
bytes.
Notes
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.
Example
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
