Why does the base pointer point to the top of the stack?
In the "Programming from the ground up" book, I see the stack frame when calling function is somewhat like this
parameter 2 <- 12(%ebp)
parameter 1 <- 8(%ebp)
return address <- 4(%ebp)
ebp <- (%ebp)
local var 1 <-…

in either one What is pushed to the stack

Why is my base case being (erroneously) triggered immediately?
I am trying to implement a merge sort algorithm in C. In the recursive array split function, my base case is occurring infinitely, despite the return statement, and the merge function is never called. Here is my code:

const int…

Move current stack frame in C
I was wondering if there would be a convenient way to copy the current stack frame, move it somewhere else, and then 'return' from the function, from the new location?
I have been playing around with setjmp and longjmp while allocating large arrays…

Is the stack frame of a function called multiple times different each time?
void foo()
{
int i;
printf("%d",i++);
}
int main()
{
int j;
for(j=0;j<10;j++)
{
foo();
}
}
The output of the code is a series of 10 random but continuous numbers.
I wanted to know how is this possible if i is being…

Using the Frame pointer instead of the Stack pointer in x86_64
Compiling a simple C code into assembly using GCC will have the following output:
...
13 xorl %eax, %eax
14 movl $0, -4(%rbp)
15 movl $5, -8(%rbp)
16 movl $6, -12(%rbp)
17 movl -8(%rbp),…

When passing an data member array into a recursive procedure, is a new copy of that array created in each stack frame?
I am facing the issue that copy of an 2 dimensional array is not made in each stack frame of recursive call. I am doing indirect recursion.
I also tried sending my data in function call from main() function but the copy was not made. Same address…

Is there a symbol table for local variables stored within a stack frame?
Logically, I would assume that there has to be. If im correct, I'm also assuming that its separate from the global symbol table, and that its created by the compiler when a function call is reached and deleted when the compiler reaches the end of…

Why do we need `pushl %ebp` at the start of every assembly program?
Why do we need these two functions at the start of every assembly program?
pushl %ebp
movl %esp,%ebp
I don't know what they do and they don't seem to contribute to the code functionality. I come from the Python world so this is pretty weird.
