Stack Frames and Local Variables
Build and tear down stack frames using the base pointer (EBP/RBP) to allocate local variables and access parameters reliably inside procedures.
Why Stack Frames?
A procedure needs space for its own local variables and a stable way to find its parameters. A stack frame gives each call its own private region of the stack.
The Base Pointer
The base pointer (EBP in 32-bit, RBP in 64-bit) provides a fixed reference into the frame, while ESP keeps moving as you push and pop.
