Syntax
Results:
The result type is the same as i. The result value is the number of 1 bits in the binary representation of the integer i.
The model for the interpretation of an integer value as a sequence of bits is shown in Model for Bit Data.
Example
If the value of I is B'0...00011010110', the value of POPCNT(I) is 5.
