-qoptimize

In IBM® XL C/C++ for AIX® 16.1.0 or earlier releases, the -qoptimize option specifies whether to optimize code during compilation and, if so, at which level.

If you were using -qoptimize in IBM XL C/C++ for AIX 16.1.0 or earlier releases, use --optimize=<level>, -O0, -O1, -O2, -O2, or -Ofast in IBM Open XL C/C++ for AIX 17.1.2 to achieve the same effect.
