Oh. How's:
This pattern is created automatically by the if_convert
pass run after reload or by target-specific splitters.

Currently it's at the end of rtl.def under the heading of:
/* ----------------------------------------------------------------------
Expressions for operators in an rtl pattern
---------------------------------------------------------------------- */
I assumed that it made more sense under the heading of:
/* ----------------------------------------------------------------------
Top level constituents of INSN, JUMP_INSN and CALL_INSN.
---------------------------------------------------------------------- */
Did I miss understand how it's used?
