GCC Compiler Receives ARM big.LITTLE Tuning Support

Patches have been published that allow the GNU Compiler Collection to tune generated binaries for ARM big.LITTLE systems.

ARM big.LITTLE SoCs are where there's commonly a high-performance quad-core Cortex processor paired with a low-power, low-performance quad-core Cortex for less demanding situations. With the latest GCC ARM patch work, there is now cortex-a15.cortex-a7, cortex-a57, and cortex-a57.cortex-a53 tuning targets for the common big.LITTLE A15 + A7 and A57 + A53 configurations.

More details on the ARM GCC big.LITTLE tuning work for the open-source compiler can be found via the gcc-patches list.
