Debugging assembly

How do I debug assembly code? I'm on Linux and have gdb handy. I know I can watch registers. What are some methods for debugging assembly code?

You can of course use breakpoints just as with C or any other compiled language, too. This article describes the process of debugging an assembly program a bit.

Of course you can use nm command with a parameter of executable elf file, it will shows you the available labels with address. From this you can set a breakpoint on a specific address, then execute a single instruction by using "si" debug command.

Using the "disassemble" gdb command you can see the assembly code that is about to be executed. This, in conjunction with watching registers, can give you insight into what the CPU is really doing.
