tell gdb to disassemble "unknown" code
assembly, disassembly, gdb
Solution
set disassemble-next-line auto
Is what I find most useful. You can also set it to "on" to disassemble even if source is available.
See the "Source and Machine Code" section in the documentation.
Problem
is it possible to configure gdb in order to debug assembly code when there are no debug symbols or no sources available ? I mean showing assembly instruction by assembly instruction when performing a step by step debug (next /step commands) (not desassembling all the function. just the next instruction that will be executed) Regards, Ayman
