Difference between int32, int, int32_t, int8 and int8_t
...ent times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits).
On the other hand, int is guaranteed to be present in every implementation of C, where int8_t and int32_t are not. It's probably open to question whether this matters to...

Extracting bits with a single multiplication
... Let's re-state the problem being asked as a theorem:
"There exists some 64-bit constants 'mask' and 'multiplicand' such that, for all 64-bit bitvectors x, in the expression y = (x & mask) * multiplicand, we have that y.63 == x.63, y.62 == x.55, y.61 == x.47, etc."
If this sentence is in fact...
