Does that mean that the expand file isn't the dump after the initial rtl
generation phase? According to internals manual, only the named
define_insn and define_expand are used during rtl generation phase.
The manual is correct, but the define_expands can produce the anonymous insns.
If you recog an insn that isn't a named pattern, you still get the
"name" of the define_insn (with the "*" in front of it) or just "" if
the insn doesn't have a name. You always get at least the insn code.
