Hi again,
The problem was not that "mull" is used, but that "gcc 3.4.6" generates highly
un-optimized code when I for example multiply a 16-bit

Ok, thanks. But really I don't want to do "((int64_t)a) * b", which I know
works, hence that is very much slower than "a * b" on intel processors
All,
Not a bug in GCC the result is correct as you've only asked for a 32-bit
multiply.
