How can I examine the stack frame with GDB?

问题:

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 everything in a function?

回答1:

For the current stack frame:

• info frame lists general info about the frame (where things start in memory, etc.)
• info args lists arguments to the function
• info locals lists local variables stored in the frame

回答2:

You can view the contents of the stack with x/10x $sp

This will print the top 10 elements of the stack.

回答3:

• bt (or backtrace) will give you a call stack.

• frame <args> will give you information about a specific frame from the stack.

• info locals can give you information about any local variables on the stack.
