Thanks everyone for jumping (groan) on this.
>From the looks of it, changing the asm goto statement itself to:
asm goto ("# Either %l[f_yes] or %l[f_no]\n\t"
"jmp %l[f_yes]"
: : : : f_yes, f_no);
... *and* adding:
asm volatile(""); /* gcc bug 44071 workaround */
... immediately before __builtin_unreachable(); does make it output correct
code, at least with gcc 4.5.0.
