In the case of a single-architecture sim (i.e., not 'multi', then
yes), GCC will automatically eliminate the test.

In the case of a multiple-architecture sim, it won't. But (a) at
least in my mind, i'm not worried about absolute maximal performance
from that configuration (if you want max performance, build a single
arch sim), and (b) until somebody quantifies the difference, I'll
claim that i don't believe it'll be a measurable difference. 8-)
