 Good call on using "repeat...until" in my own code, thanks!

 I wasn't clear, but my intention was also keeping the conditional check at
the end of the loop, but duplicating it at the start with the condition
inverted.  In other words, having both these example code segments:

     xorl    %r10d,%r10d
     movl    $1,%r11d
     movl    %edx,%eax
     cmpq    %rax,%r11
     jge  .Lj7
     .balign 8,0x90
 .Lj6: //
