English Amiga Board - View Single Post - I am trying to make my first GFX assembler code

Code:

    moveq   #-1, d0
.1  tst.b   (a0)+
    dbeq    d0, .1
    add.l   d0, a0
    not.l   d0

But isn't Bcc faster than DBcc?

Code:

    move.l  a0, d0
.1  tst.b   (a0)+
    bne     .1
    sub.l   d0, a0
    exg     a0, d0
    subq.l  #1, d0
