Except that it only tells you that it can't be inlined by that particular
compiler on that platform - not that a different gcc version couldn't do
it, or a different compiler (clang, Solaris Studio, Intel, etc.) couldn't.

Also, some of the warnings it generates in the Xserver are simply "optimizer
decided it was unprofitable to inline at this particular call site", not
"you designed this function in a way the optimizer can never inline it

As I said, if you're doing specific performance tuning, I can see turning it
on, but in general builds it seems more like noise drowning out more useful
warning messages.
