About GDB user-defined commands ?

[Peter.Schauer]

Try:

define dm
set var $taddr = $arg0
set var $tsize = $arg1
while $tsize != 0
   if $tsize >= 10
     monitor dm $taddr $tsize
     set var $taddr = $taddr + 10
     set var $tsize = $tsize - 10
   else
     monitor dm $taddr $tsize
     set var $tsize = 0
   end
end
end
