eax

In the mean time i also come up with this code :

mov ecx,32
mov eax,00fffff0h


doshift: shl eax,1
jc setcount
setcount: inc count
loop doshift

But then the result i got in count was 32 ,

Could you point out the flaw in this piece of code ?

DaWei

Sure. It jumps to 'setcount' if there's a carry, and falls through to 'setcount' if there's no carry. The result is to count, regardless. I recommend that you make a flowchart from your code and analyze it. For instructions like "loop", be sure and break them into their entire function. "loop", for instance, would be, "decrement ecx", "test ecx", and "jnz label operand".

eax

Since its Assembly Language forum ,

Could you also help me with CFG's ( Context Free Grammar) ?

or any other questions on Automata Theory ?

linxis

What language
asembly can be: masm, nasm, tasm, hla, casm, machine, binary, DA, c++

You're mistaken. Assembly is not a tool. Assemblers are tools. Please try to contain yourself when it comes to dredging up old threads.
