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.
