   I would just use the disassembler, for example `x/10i _start` instead of   
   `list _start`!   
      
   I don't think nasm will generate line info automatically (just names),   
   so you would set breakpoints on symbols `b _start` or addresses `b   
   *0x401000)   
      
   However... gas can do it if you prefer this style. Your code is   
   basically valid gas syntax already. Just add `.intel_syntax noprefix`   
   and add a `.` before directives, e.g. .section, .global, etc, and use #   
   for comments instead of ;.   
      
   Then you can use `as -g foo.asm -o foo.o` instead.   
      
   Now `b foo.asm:123` should work.   
      
   Nasm and gas are both great assemblers, it doesn't make much difference   
   which one you choose while you're getting started.
