I am new to GDB, so I have some questions: How can I look at content of the stack? Example: to see content of register, I type info registers. For the stack, what should it be? How can I see the c...

Aug 30, 2013 · Right now I've been using GDB to disassemble a binary file and check out different registers and whatnot. Is there an easy command to examine everything on the stack? Can this be limited to everyth...

I like your approach! Is there any good gdb plugin that allows to examine the heap showing it's chunk data, headers, in-use bits and the like? I just found gdb-heap. Unfortunately it seems pretty outdated and unmaintained.

Oct 12, 2023 · The output here is very like info args, but GDB is just printing the stack locals. You can always print particular locals, arguments, or globals like print var -- assuming of course, that you are in a frame where that variable is valid. To learn more, GDB has a built-in help system, so you can do help COMMAND to get more info, e.g. help info ...

Jan 26, 2017 · If you do have debug informations of your binary, you can use info locals to list local variables of the selected stack frame, and navigate in the stack using frame, bt, info frame, info frame <address>, up, down, etc. You can't really "annotate" the memory, but what you could do is create convenience variables to dynamically create GDB variables.

Nov 27, 2010 · @Frédéric Hamidi: bt full gives you local variables, function arguments, etc. too but he wanted to get more frames than what gdb shows usualy.

movq $22, -8(%rbp) And so I could do something like a "stack" command and it would print (at least) something along the lines of: 00 00 00 00 00 00 16 Without having to write something fancy with the p/x command that I need to look up to remember how to do it. Is there a straightforward way with gdb to print a readable-ish stack?

Nov 1, 2021 · You can show the stack with the command info proc mappings. The stack's information is at the bot (gdb) info proc mappings process 2281 Mapped address spaces: Start Addr End Addr Size Offset objfile <SNIP> 0xfffdc000 0xffffe000 0x22000 0x0 rwxp [stack] In this case, the size is 0x22000.

May 3, 2021 · Is there an equivalent command in GDB to that of WinDbg's !process 0 7? I want to extract all the threads in a dump file along with their backtraces in GDB. info threads doesn't output the stack tr...

Jun 14, 2017 · I'm doing some assembly-level debugging in GDB. Is there a way to get GDB to show me the current assembly instruction in the same way that it shows the current source line? The default output after...
