Please don't top-post.  Thanks.

I guess I don't understand the question.  I thought you were asking
where rtx_name is defined.  It's defined right there in the code that
you quote.  The contents of rtx_name are filled in by the #define of
DEF_RTL_EXPR which is just above the code that you quote, and the uses
of DEF_RTL_EXPR in rtl.def.

If that is not your question, can you explain further what you are
asking?
