    Re: optimizing an algorithm or two

    I dont use any floating point variables or intermediates anywhere.
    I donr use any ASSERT statements.

    Re: optimizing an algorithm or two

    Why? I thought running the debug code outside of the debugger was pretty much the same as running the release code. Anyways I just added some code to the ENTER/EXIT macros to take a clock reading,...

    Re: optimizing an algorithm or two

    I want to say they are using a byte array to represent a twos complement number. I tried having my arrays represent a twos complement number, but, at the time, the code looked cleaner using the...

    optimizing an algorithm or two

    Hello all,

    Same project as Ive been posting about. After the replies I got from my last post, Ive been spending some time redoing parts of my library. When I got to the assembly code and read...
  8. Re: You never get bored or tired of programming stuff?

    Im just a dumb a$$ carpenter. I dont touch a computer all day, but at the end of the day when I am trying to wind down, Ill turn on the computer and work on one of my projects. For me, it is...

    Re: Class fraction - overloading operators

    Noone here will "do" your homework for you. With that in mind Ive written the library you are talking about, it took about a few weeks to get most of what youre asking for up and running but I also...

    Just learned that the hard way lol.

    Youll find most everything in the above article, Ive reread those pages a hundred times it seems. If you dont completely get a part of it you...
  17. Re: Question about volatile registers

    So, in the middle of typing that last reply, when I got done typing that last bit about how it doent throw an exception till it requests more memory when I remembered something OReubens said:

  18. Re: Question about volatile registers

    Funny you should mention that post, I just reread it the other day. As this project has evolved every once in a while Ill see a way to reduce its complexity, code an idea or two and test it out, if...
  19. Re: Question about volatile registers

    http://msdn.microsoft.com/en-us/library/9z1stfyw.aspx

    I keep coming back to this article describing register usage and looking at r10/r11


    r10 and r11 are the only (integer) registers marked...
  20. Re: Question about volatile registers

    sorry took 3 posts to get everything in:


    Now there is a bit of extra code in there trying to debug this problem, hopefully its commented enough to understand a few things though:

    And the following would be equivalent to function2:

    ;each table is specific to a memory set
    ;each entry...
  22. Re: Question about volatile registers

    Ok, I have to break this post in two parts (it said Im almost double what it allows to post).

  23. Re: Question about volatile registers

  24. Re: Question about volatile registers

    I am not sure where its going wrong, all I can say so far is that r11 is correct before the call to function2, and that every once in a great while it gets corrupted between the function call and its...
  25. Re: Question about volatile registers

    One more thing, it appears to happen in multi-threaded mode but not when run in single threaded mode (only about 95% sure of this at the moment though). Im still running it in different modes to see...
