	Roger provided some good justification for the patch in a thread

Dan's patch helps SPEC CPU2000 a little, but I think the primary
motivation is its benefit to real world code and providing a common
optimization that other commercial compilers implement.  The patch will
help the performance of GNU/Linux systems.

I find it totally plausible that this will help real world code, but I'd like some evidence. I understand that SPEC is not the be-all end-all; is there an application out there that shows that this is a win?
