Hello Friends,
I am working with Embla which is a data dependency
analysis tool and uses Valgrind for its operation. As in an C/C++ program
there could be number of methods/procedures/ functions that could be
called. I am in search of any suitable method so that valgrind will inform
my tool when ever control reaches at a point which i would like to pay
special attention. For example consider following code snapshot.
1: #include<stdio.h>
2: #include<stdlib.h>
3:
4: void pro1(){ /* do something;*/}
5:
6: void pro2(){ /* do something else */}
7:
8: void pro3(){ /* do some thing*/}
9:
10: int main(){
11:
12: void (*fn)(void);
13: void (*fn2)(void);
14: void (*fn3)(void);
15:
16: fn=pro1;
17: (*fn)();
18:
19: fn2=pro2;
20: (*fn2)();
21:
22: fn3=pro3;
23: /**
24: * at this point valgrind should tell my tool that it is going to
call pro3
26: */
28: (*fn3)();
29:
30: return 0;
31: }
In above snapshot at line # 28 we have used a function pointer to call pro3
method. I want to know a suitable method using some sort of macro or other
construct that i could insert in the program that my tool is analyzing, and
valgrind inform my tool about those points when these points are about to be
executed.
