This PR adds a new
BitVec.popCount
operation and a corresponding circuit tobv_decide
, allowing to bitblast the population count (popCount
) operation. The AIG circuit is implemented according to Brian Kernighan'spopCount
algorithm in the bitblaster, to count the numbers of bits set in a bitvector (popCount
).popCount
is common in numerous compiler intrinsics (see here) and architectures (see here).
