-qnamemangling (C++ only)

In IBM® XL C/C++ for AIX® 16.1.0 or earlier releases, the -qnamemangling option chooses the name mangling scheme for external symbol names that are generated from C++ source code.

In IBM Open XL C/C++ for AIX 17.1.3, the Itanium-based C++ABI of ibm-clang++ does not support prior C++ABI name mangling.
