Hi Nicola,

my patch is too simple compared to yours, feel free to work on it as much 
as you wish, no need to credit me since you posted it independantly. I 
just posted it to note that the inlining part is the one providing most 
performance benefit.

richi: I used always_inline because it is the case that you *never* want 
it to be out-of-line, since it's a small wrapper function providing 
important performance benefit. Do you think a macro would be better?


P.S. Nicola, if you remember it, please keep me Cc'd in further posts of 
yours related to performance of gcc
