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.
