MadeEasy Test Series: Compiler Design - Register Allocation
The following program uses six different variables p, q, r, s, t and u. The code is: p=6 q=7 t=p*q s=t+p u=8 u=s*p s=p+u r=r*q t=t+p return t Assume that all operations take their operands from registers, the minimum ... is 5, but my answer is 4. I think that the step u=8 can be skipped since 'u' is being reinitialized in the next step.
