Once GCC 4.0 is out, I'll experiment with it and submit test cases etc. for it.
 No use trying to fix an older release's optimisations IMHO.

Thanks anyway.

There's also other stuff lurking in assembler files, such as a lot of 
notes for labels. These aren't code, and I've seen cases where newer 
compilers output more labels than older ones for some reason. 
 
Unless you show us some run-time comparisons, I guess there isn't much 
willingness here to do something about it. I'll put this PR into "waiting" 
state. 
 
Thanks 
  Wolfgang

Notice that I would prefer to see a runtime benchmark before confirming this 
bug. A 20% increase in code size could probably be caused by better inlining -- 
it does not automatically means that the code is slower unless you prove 
otherwise.

If you compile with -O2, you should test run-time speed with a run-time 
benchmark: try doing some calculations and time them with different compilers. 
If you care about code size, try with -Os.

First this is invalid code as explained in PR 18415.
Second this works fine on the mainline as get close to optimial code.
