Yes you should tell us which is the inlined function that generated
different asm (if you post the two differnt asm or the two different .o we
can probably find it ourself).

I seen the rw_spin_locks are silly requesting the address of the spinlock to be
in the register eax when the address of the spinlock isn't a constant (while it
should instead at least use "r" and not "a") and I was going to fix it, however
that's not changed between test7 and test8...
