Hi Gerald,

> warning: '__tmp' might be used uninitialized in this function
Assuming you are speaking about the tip of "tree-ssa-20020619-branch"
or "tree-ssa-cfg-branch" (sorry, I test neither and do not know which
is definitive, if either, based on context), I think the warning
itself must be in error based on the contents of line 50:
register _Atomic_word __result, __tmp = 1;
(I assume that no later C-level statement could invalidate __tmp in
any manner which produces that warning. In FD, there is a
semi-vetted __asm__ construct but it looks legit to me...)
Regards,
Loren
