Would it? If you don't have numbers you have *nothing* to back that
assertion. We see hand waving advocacy every couple of months about this
subject, but in the past several *years* no one has cared enough to do
some real research and demonstrate a benefit. "It Stands To Reason" is
frankly a ridiculous justification for change.

FYI, gcc has a long history of mediocre optimizations, and it
is well known that optimizations that make some processors faster can
slow down other (even newer) processors (that is, general optimizations,
not gcc-specific).
