profiling for memory usage

[icegood]

I want to profile program for memory usage (both physical and virtual) per functions.
More precisely i've tried both valgrind and grof with no luck.
Is there for debian smth better?

What do you mean 'profile' memory usage?

void foo ( char *p ) {
  for ( i = 0 ; i < n ; i += 100 ) *p = 0;
}
void bar ( char *p ) {
  for ( i = 0 ; i < n ; i++ ) *p = 1;
}
int main ( ) {
  char *p = malloc(n);
  bar(p);
  foo(p);
  free(p);
}

All 3 functions use the same amount of memory (from one point of view at least).
From another point of view, main doesn't use any, and foo uses only 1% of what bar uses.

Would cachegrind help?
Valgrind

By profiling memory usage i mean output like that:
<func_name> <mem allocated inside> <mem deallocated inside>
... ... ...

cachegrind? No, it's for simulating of processor cache (or at least i don't see, maybe i'm wrong?). Memcheck should do so, bt it isn't.


Now i'm trying to work with gperftools with no luck yet because it seems buggy

So for my example program
main.c:8 allocated n bytes
main.c:11 freed n bytes

And so on, for each unique block of allocated memory.

what is about? valgrind --tools=cachegrind?

[icegood]

moreover i need tool to be able to print whole stack if memory changes even inside library (a static one with debug symbols).

Wonderful link
But nothing works proprerly, CCMALLOC too old and have Seg Fault inside, Under gperftools i'm suffering on:
this
tried Dmalloc, - too complicated, and seems to be unusable for external library.
What else do you propose?
