-q32

@PROCESS

None.

Purpose

Enables 32-bit compilation mode (or, more briefly, 32-bit mode) support in a 64-bit environment.

Syntax


>>- -q--32-----------------------------------------------------><

Defaults

-q32 is the default, if you have not specified either -q32 or -q64 and if you have not set the OBJECT_MODE environment variable. For a description of the OBJECT_MODE environment variable, see Default bit mode.

Usage

The default integer and default real size are 4 bytes in 32-bit mode.
The default integer pointer size is 4 bytes in 32-bit mode.
32-bit object modules are created when targeting 32-bit mode.
-q64 will override -q32.
All settings for -qarch are compatible with -q32. If you specify -q32, the default -qarch suboption is ppc, and the default -qtune suboption for -q32 is balanced.
The LOC intrinsic returns an INTEGER(4) value.

Examples

Using 32-bit compilation mode and targetting a generic PowerPC® architecture:
```
   -qarch=ppc -q32
```
Now keep the same compilation mode, but change the target to POWER5:
```
   -qarch=ppc -q32 -qarch=pwr5
```
Notice that the last setting for -qarch wins.
Now keep the same target, but change the compilation mode to 64-bit:
```
   -qarch=ppc -q32 -qarch=pwr5 -q64
```
Notice that specifying -q64 overrides the earlier instance of -q32.
