ARM Cortex-A15 Exynos5 Compiler Benchmarks

With Dolfyn is the first test where we saw a noticeable change in performance when moving from GCC 4.6.3 to the latest GCC 4.7.2 stable release. Unfortunately the change wasn't in a positive direction with this computational fluid dynamics test profile being slower under GCC 4.7 on the Samsung Exynos 5.

With FFTE, on the other hand, GCC 4.7.2 positively influences the ARMv7 Cortex-A15 performance for this FFT OpenMP-based benchmark on the dual-core 1.7GHz ARM SoC.

The SciMark computational C tests were overall moving in a positive direction with GCC 4.7.2.
