[PATCH][Arm] Set Armv7-A tune to Cortex-A53

2019-11-18 Thread Wilco Dijkstra
By default Armv7-A tunes for Cortex-A8. This is an ancient core today and the settings are no longer useful for newer cores. So switch to Cortex-A53 tuning since it works well across a wide range of modern cores. On SPECINT2006 the performance gain is 0.7% compared to Cortex-A8 tuning, and codesiz
