gcc supports that, but needs profile data to be available:
Reorder functions in the object file in order to improve code
locality. This is implemented by using special subsections
".text.hot" for most frequently executed functions and
".text.unlikely" for unlikely executed functions. Reordering is
done by the linker so object file format must support named sec-
tions and linker must place them in a reasonable way.
Also profile feedback must be available in to make this option
effective. See -fprofile-arcs for details.
Enabled at levels -O2, -O3, -Os.
