terms of performance) to non-standard CFLAGS. -O3 is 2x slower than -O2,
due to hand-unrolled loops! I don't know how the -m* flags that you add
will interact with such loops. Anything except mere -O2 is de-facto
untested and unsupported in terms of performance (but should still be
correct unless the compiler documentation says otherwise).

Another example, Pulse explodes with -ftree-vectorize
