I am trying to write a program that is 100% iterative, that is, the functions never need to return, because nothing must happen after such a return.
In other words, the program is 100% in tail position.
Consider the following toy program:
def…
My problem is that I don't understand some things in the GDB output by debugging the program.
Here are the following lines of Intel assembly code on Arch Linux.
segment .text
global main
main:
push rbp
mov rbp, rsp
Here is the…
I am working on an assignment right now for ARM 7 (Big Endian) Assembly. We are using LDMDB and STMIA for this problem where we have an empty ascending stack, where I am asked to push the frame pointer value to the top of the stack. Then I am asked…
I'd like to create a variadic function that sums its inputs. I've managed to write inline assembly for capturing arguments 2-6, but I'm struggling to retrieve the other arguments from the stack frame.
I'm trying to solve a coding exercise that…
I am new to assmbly, and I have some problem. I compiled the following code with GCC:
.intel_syntax noprefix
.section .data
number:
.int 65
message:
.ascii "The number is %d %d.\n\0"
.section .text
.globl _main
_main:
push ebp
…
So, heres how I interpet the stack, let me know what is wrong/right. This is for any sort of assembly.
So it goes:
Directives
Bytecode with instructions
A 'stack' of added bytes added to the end of the instructions (these are set to 0 if I recall…
Say I have a method PrintSourceCode(Action action) that accepts an Action delegate and is executed this way:
PrintSourceCode(() =>
{ // need this line number
DoSomething();
})
Within PrintSourceCode I would like to print the source code of the…
How do I get the caller class type in the base?
this is the parent, here I want to print the child type without sending it
public abstract class Parent: ISomeInterface {
public void printChildType()

I've got a question about this code:
#include
void bar(void)
{
int a = 22;
}
void foo(void)
{
int a;
printf("%d\n", a);
}
int main(void)
{
bar();
foo();
}
Why is it displaying 22 like it was assigned in bar…
I'm trying to learn more about generator functions in Python. To my knowledge, generator functions don't fully return until there are no more yield calls, so a stack frame exists in the generator returned by the function.
Stack frames should have…
As far as I understand, stack variables are stored using an absolute offset to the stack frame pointer.
But how are those variables addressed later?
Consider the following code:
#include
int main()
{
int a = 0;
int b = 1;
int…
Consider the following scenario in the programming language C:
void f(char* name, int age){
}
int main(int argc, char* argv[]){
char* name = argv[1];
int x = 1
f(name, x);
}
How would the stackframe of f() look like in this situation?…
After reading the following excerpts from C# documentation StackFrame Class, I still don't understand what the term "thread" means. What is a thread??? what does it mean in regards to a C# program in relevance to the call stack and stack…
I saw a piece of code like this in asm:
.text:787924E0 testcall proc near

.text:787924E0 var_34 = byte ptr -34h
