Provided that increased register pressure doesn't ruin the benefits of
inlining. The new register allocator may help, too.
It'd be nice to have a study on the effects of inlining real-world code
with GCC on multiple targets. I haven't seen any, and chances are any
that already exist are obsolete anyway. Meanwhile I've noticed a lot more
hand-waving arguments than real numbers.
