The standard names all have modes built into them.  If you are porting
gcc, then you need to write a define_expand or define_insn in your MD
file with a standard name which incorporates the vector mode that you
are using.  Using the standard name will enable the middle-end of gcc
to know about your operation.  There are many examples in the existing
gcc backends.
