Does armlink support extern "C++" syntax in symbol versioning script files?

Answer

ARM Compiler toolchain v4.1 patch 1 and earlier does not support the extern "C++" syntax in symbol versioning script files. As a workaround you can use a wildcard character to match the mangled symbol name, for example:

{
  local:
        *foo*;
};

In ARM Compiler toolchain v4.1 patch 2 and later armlink supports matching of C++ unmangled symbol names in symbol version scripts in the same way as GNU ld. For example:

VERS_2.0  {
    global:
        extern "C++" {
            ns::*;
	    "foo::f(int, double)";
    };
    local:
        *;
}
