open64 - production ready tool?

Hello,
I googled a little bit and I wonder what is real-world experience of
users with open64?
Is there anything one could probably gain by using it instead of gcc
or icc?
I found two benchmarks, though benchmarks rarely tell the truth about
the quality...

and one bonus question: does anyone know how does it compare to
mipspro on mips platform (let's say r10k or so).

cheers

open64() is the POSIX API to open files larger than 2GB and as such would
topical in comp.unix.programmer, not here.
But as you compare mit with gcc, icc and mipspro, I guess open64 is a
compiler? If so it might be topical in comp.compilers, but again not here.

A little googling reveal that it indeed is a compiler and for C/C++ it is
said to be a frontend to gcc, so comparing it to this is mute, isn't it?

That's where I tried to post first. Moderator sent me here.

no it is not.
don't believe wikipedia blindly.
from open64.net page:
"CAPSL and Hewlet-Packard are currently working on Osprey, a project
to replace Open64's front end (derived from GCC 2.95's frontend) with
the current GCC front end."

it uses gcc only as front end, doesn't mean it's not compiler itself.
