I'm contemplating a port to the TI DM642 DSP. One issue that's sure to crop up is the size of longs on this platform. ULONG_MAX is 1099511627775, but sizeof returns 8 due to alignment issues. [...]Weird.
DSP-s are special purpose hardware, it looks like they set the length of long to be that of teh accumulator (which makes sense as a += b*c and similar will be able to then be coded to not to overrun). the sizeof hack is just a product of no software out there knowing what to do with non power of two sizeofs (yes, its a gross hack)
