together, and leaves the result in its destination (first) operand.
The destination operand can be a register or a memory location.
The source operand can be a register, a memory location or an
immediate value.
The flags are set according to the result of the operation: in
particular, the carry flag is affected and can be used by a
subsequent ADC instruction.
In the forms with an 8-bit immediate second operand and a longer
first operand, the second operand is considered to be signed, and is
sign-extended to the length of the first operand. In these cases,
the BYTE qualifier is necessary to force NASM to generate this
form of the instruction.
