GCC 5.2 Compiler Benchmarks With ARM Cortex-A57 A Mixed Bag

Following Monday's NVIDIA Jetson TX1 performance overview one of the first follow-up tests I wanted to carry out was to see how the performance would evolve if using a newer compiler than what's shipped in Ubuntu 14.04. This current long-term support release ships GCC 4.8 while out since then was GCC 4.9 and now GCC 5.2.1 with GCC 6 coming in just a few months.
