-qpriority (C++ only)

In IBM® XL C/C++ for AIX® 16.1.0 or earlier releases, the -qpriority option specifies the priority level for the initialization of static objects.

IBM Open XL C/C++ for AIX 17.1.3 does not support a functionally equivalent option to -qpriority, nor does it support pragma priority. IBM Open XL C/C++ for AIX 17.1.3 supports the __attribute__((init_priority)) attribute that provides a similar function to -qpriority, with which you can specify non-default priorities for initialization in source code. The default priority between IBM XL C/C++ for AIX 16.1.0 and IBM Open XL C/C++ for AIX 17.1.3 is the same. However, the value range of the priority level in __attribute__((init_priority)) is different from that of -qpriority. As a result, there is no guarantee of relative ordering between the objects compiled with IBM Open XL C/C++ for AIX 17.1.3 and the objects compiled with IBM XL C/C++ for AIX 16.1.0 or earlier releases.
