initauto

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
