Not quite.  There is less generated code, but it requires
extra registers to hold the return addresses so the register
pressure is higher.

Some of that extra register pressure may be artificial and
go away when this bug is fixed.  Some of it may result from
poor choices of the register allocator, and may be remedied
by enhancing the register allocator.  There is hope of
remedies as the kind of code presented to the register
allocator is very different when code is not inlined.

Hmm.  At least with reboot=hard that should work on the Opterons.
I have not tested that lately though.
