Assembly IF statement simple question

Elias Gold

If I say,

if a == 10 b = b * 4 + 2

if it does then do 'b = b * 4 + 2' or skip doing it? Would it be BNE or BEQ?

Something tells me it's DON'T DO...

Thanks

    Stop being so negative!

    Either BEQ or BNE could be used. It simply depends on how your code flows.

    Why don't you try breaking your code up a little more and see what might be the best solution?

    if a == 10 b = b * 4 + 2

    You must surely be able to see that it could flow something like:

    
  CMP  A,#10
  BNE  Skip

  Do the maths

Skip:

  Continue

    But if your code was part of a subroutine it might be:

    
  CMP  A,#10
  BEQ  Continue

  return

Continue:

  Do the maths

  return

    I'll assume you can interpret my pseudo code/instructions.
