You don't need that target clause in gcc.target/powerpc (and dg-do compile
is the default, but having it explicit is also fine of course).

You can remove powerpc_fprs now because it became redundant? Cool.
But dfp_hw is the wrong conditions for a dg-do compile test.
Nice cleanups! Please fix that dfp_hw thing, and then, okay for trunk,
Thanks!
