You really should know that we only care about code size at -Os. We care
about performance
regressions though at -O2.

Code size is important for performance for modern processors. Small I-cache (and
I-TLB) footprint for otherwise equivalent code results in better performance.

Then use -Os every where instead. You will see that the overall code size for 4.1
has reduced from 4.0.
