Obviously mspgcc is doing a lot more than I expected of it ;)
Good luck,

You're right, the code has been in there since gcc-3.3. For some reason
I assumed that the latest windoze installer would have the latest gcc
in it.
The one I have installed (20041112) contains gcc v3.2.3, so that
explains why the 32x32=64 isn't in there. I looked at the libgcc.S file
in version gcc-3.3 and that one contains the full 32x32=64 with hw
multiply.
Do you know where I can download a prebuilt binary based on gcc-3.3 or later?
When I said I used gcc-3.3, I was referring to the mspgcc subdirectory,
which is what actually works with gcc-3.2.3. This historical accident
has confused many. My version of msp430-gcc is in fact gcc-3.2.3, so you
really should have the 32x32=64 functionality, but you probably need to
call the functions instead of using c = (int64_t) a*b. At least that is
how I understood dmitry's response.
