Back when I was an intern for IBM, the TOBEY compiler back end was
state of the art. I don't have any numbers, but it was quite
competitive with anything else in the market when I worked there 7
years ago. (Of course, how good any particular compiler looks really
depends on your benchmarks...)


AFAIK, this back end is still used in all IBM compilers for all
languages that target PowerPC or Sparc. They had quite a good (and
large) development team when I worked with them -- and I suspect they
still do. I would imagine that you would have difficulty finding any
well known optimization which is not in there in some form or another.
(And it probably has several not-so-well known ones as well.)
