Power/Energy Awareness in GCC

[Ghassan Shobaki]

Hi,

Does GCC currently have any power/energy reduction 
optimizations or any performance optimizations that take power/energy 
consumption into account?
We are currently working on a research 
project on instruction scheduling for low power (experimenting with 
different algorithms for minimizing switching power) and would like to 
find out if GCC already has such a scheduler and how it can be enabled, so that we can experiment with it.
