long subtract
Code: 23 F8
Description: Subtract with borrow in and check for overflow. The result of the
operation, put into Areg,is Breg minus Areg, minus bit 0 of Creg.
Definition:
if (diff
> MostPos)
{
Areg
′← diff − 2BitsPerWord
IntegerOverflow
}
else if (diff
< MostNeg)
{
Areg
′← diff + 2BitsPerWord
IntegerOverflow
}
else
Areg
′← diff
Breg
′← undefined
Creg
′← undefined
where diff
= (Breg − Areg) − Creg
0
–
the value of diff is calculated to unlimited precision
Error signals:
IntegerOverflow can be signalled.
Comments:
Secondary instruction.
