Option Type | Default Value | #pragma options | C | C++ |
-qoption | noinitauto | INITAuto | x | x |
Syntax
-qinitauto=hex_value | -qnoinitauto INITAUTO=hex_value | NOINITAUTO
Purpose
Initializes automatic storage to the two-digit hexadecimal
byte value hex_value. The option generates extra code to
initialize the automatic (stack-allocated) storage of functions.
It reduces the runtime performance of the program and should only
be used for debugging.
Notes
There is no default setting for the initial value of -qinitauto;
you must set an explicit value (for example, -qinitauto=FA).
Example
To compile myprogram.c so that automatic stack storage is
initialized to hex value FF (decimal 255), enter:
xlC myprogram.c -qinitauto=FF
