#98568 - That's why you need Assembler!
Responding to: Jan Waclawek's previous message
Jan Waclawek said:
... the major drawback is, that you need to perform the simulation/cycle counting each time whan you recompile

That is why you'd use Assembler - then you'd know that it would stay the same unless you specifically changed it.

while the integrated "profiler" will return the up-to-date result upon each compilation.

But you'd still need to check the "profiler's" result each time to ensure that it was still acceptable.

Again, if the timing is so critical as to need this, then you really should be writing it in assembler - so that you know it won't change unless you specifically make it change!
