Yes, we probably should mention ARM too because I see "The Athlon and K8
ports have been converted to use the DFA processor pipeline
description".

I'd add Itanium too.  The first, gcc 3.4 got tuning for Itanium2 (which
is default now).  Gcc 3.4 got DFA scheduler and DFA insn bundling for
Itanium1 and Itanium2.  It results in 3% better code (SPECINT2000) for
Itanium2 and in 60% faster compiler for Itanium2.
