ARM Cortex-A15 Exynos5 Compiler Benchmarks

In summary, binaries compiled with GCC 4.7 shows better performance compared to binaries compiled with GCC 4.6, on most benchmarks.

But I would like to see a deeper analysis of the benchmark results that are actually worse with the newer compiler.

Remember that compiler benchmarks are useful only for telling you how long it takes to compile.[1]

When you cross architectures the effort of compiling can change radically. It doesn't end up telling you anything meaningful about the platform.

[1] which can be the most important metric to you.
