GCC Compiler Receives ARM big.LITTLE Tuning Support
Written by Michael Larabel in Compiler on 17 December 2013 at 08:50 AM EST. 1 Comment
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.
