Hi all,
I am currently using python interface to run a non-interactively script
based on LLDB to trace the variable changing during each step during the
program running.
C allows a variable to be declared at first without initialization. And
the value of the variable after declaration could be a random value before
initialized according to my test using LLDB with the following code compiled by
clang+llvm.
----Example Code ----
#include <stdio.h>
#include <stdlib.h>
int g = 42;
float u = 5;
struct node {
int field;
struct node* next;
};
void f() {
g = g + 1;
printf("Hello world!\n");
}
int main(int argc, char *argv[])
{
int x;
int y=10;
x = y+1;
struct node* root = (struct node*)malloc(sizeof(struct node));
root->field = 3;
root->next = (struct node*)malloc(sizeof(struct node));
root->next->field = 2;
free(root->next);
free(root);
int i = 0;
i = i + 1;
f();
return 0;
}
-----End Example Code ----
My question is:
In LLDB, is there a way to check whether a variable is currently be
declared, and have not been initialized? So that my non-interactively script
could check this, and ignore to show it before initialized ?
Thanks very much.
Best,
Kun Ling_______________________________________________
