I appreciate your efforts so far and hopefully one of the gurus could
be so kind to try out the following simple code and see whether the
correct stream gets generated:
uint32_t a,b;
uint64_t c;
c = (uint64_t) a*b;
Looking at the mspgcc source everything look fine, although the portion
of code with !defined(MSP430_HAS_HWMUL) gets used when I compile -
quite puzzling.
