Quite possibly he's not. To summarize what I have observed so far:
We have observed no bugs when compiling without -O, so that seems to
be a viable platform.
We haven't observed any bug with left shift of long long int, even
with -O.
We have observed some bugs with right shift of long long int with -O;
e.g., (long long int) 0x27a1ad6e467a7e63 >> 1 evaluates to (long long
int) 0x1467a7e63 in some cases. (I'm guessing about the "1" here; I
don't know the specific value yet.) We don't yet have a small test
case that illustrates the problem, but I hope Matthew Woehlke can
write and test one for us. Unfortunately it'll most likely be a
run-time test, but we can arrange for it to be invoked only on hosts
that have long long int but not unsigned long long int, which should
be a pretty small sample.
