A.2.181.1 Defaults

The default is -xvector=%none. If you specify -xvector, but do not provide a flag, the compiler assumes -xvector=lib.

Interactions

If you use -xvector on the command line without previously specifying -xdepend, -xvector triggers -xdepend. The -xvector option also raises the optimization level to -x03 if optimization is not specified or optimization is set lower than -x03.

The compiler includes the libmvec libraries in the load step.

If you compile and link with separate commands, be sure to use -xvector in the linking CC command. See 3.3.3 Compile-Time and Link-Time Options for a complete list of options that must be specified at both compile time and link time.
