I would really like a debugging tool that is able to visualise the current stack frame (bytes between RSP and RBP) as a block diagram.
Something like this, but with real execution values in the…
In the Call Stack window of visual studio, it reports:
[Frames below may be incorrect and/or missing, no symbols loaded for IPCamera.ax]
What does it mean by Frames, and why missing symbols may cause it incorrect?AFAIK,symbols are just for…
After reading the following question, I understand that there no such thing exist (at least not 'portable').
However I am starring at the following piece of code from mono code base, which return a pointer to the stack:
static void…
I know com.sun.jdi.StackFrame could provide the ability to access the local variable and parameters of a suspended thread. And I wonder is there a same function in Android?
What exactly does "reserve" mean in this context and how does decrementing the stack pointer reserve space on the stack? Does adjusting the stack pointer register have some side effect?
"Reserving space" sounds like memory allocation but memory for…
I'm working with LLVM and somewhat new to it.
I'm having trouble figuring out what LLVM means by stack frame lowering. Can someone explain what it is?
Any help is appreciated
Let's say, I obtain a stack frame using sys._getframe(1), which is obviously not the current frame.
Now I want to, in some way, move to the outer stack frame and execute a statement, like maybe x=10, so as to create a variable in that frame.
I…
I succeeded in implementing bytecode method inline optimization and the generated code seems OK for me. Yet, the verification fails with message:

I have the program below. If i declare variables a,b,c static global variables, it gives segmentation fault, but if i declare them non-static global or as local variables, it won't give segmentation fault. Why does it behave in such a way? I know…
I have a python script that I run with 'exec'.
When a function is called by the script, I would like it to know the line number and offset in line for that call.
Here is an example. If my script is:
foo1(); foo2(); foo1()
foo3()
And if I have code…
This is the program:
#include
void test_function(int a, int b, int c, int d){
int flag;
flag = 31337;
}
int main(){
test_function(1,2,3,4);
}
From GDB:
Breakpoint 1, main () at stack_example.c:14

Will the compiler produce the same code for both of these statements?
foo1(int* val){(*val)++;}
foo2(int &val){val++;}
Will it simply write a pointer into the parameter part of foo's stack frame? Or, in the second case, will the callers' and foos'…
I was wondering Are these scenarios ever possible for a compiler to do?
first we define SomeDataType as:
struct SomeDataType{
public:
int a;
int b;
int c;
};

I'm currently playing around, examining stack frames, trying to get an idea of how this works. After reading a few articles that always explained that the general structure would be:
local vars <--- SP low address
old BP <---…
If I insert a new functions and instructions that within the stack frame to assembly x86 code, is it necessary to increase the stack size? if yes by how much?
