The competition has changed, it is about being fast, not about doing something somebody else cannot do.

The compiler will most certainly not break good design of your C source, even if the optimizer changes. The actual compiler itself (which is input independent and machine indepent except for inline assembly code) which does the global optimizations has not changed a lot. Loop unrolling, dependence detection and things don't change a lot in the way they work.
