GDB single stepping assembly and displaying the next instruction which will be executed. [duplicate]

Question

Using the gdb debbuger what command can I execute to single step and display the next instruction that will be executed? I'm familiar with windbg where this operation is pretty straight forward.

So for example I have the following function and as I step into the code via si I want to display the next instruction that will be executed without having to do a full disassembly via disassemble. How can I accomplish this?

Answer 1

I found that the following sequence of instructions accomplishes my objective.

(gdb) show disassemble-next-line
Debugger's willingness to use disassemble-next-line is off.
(gdb) set disassemble-next-line on
(gdb) show disassemble-next-line
Debugger's willingness to use disassemble-next-line is on.

Thanks Olaf!
