when i use -flto "weak symbol" are converted to "t". 

I really don't know whether this is bug or expected behavior, because in GCC
Source i am not able to find the code for this conversion. 


@akhilesh-ubuntu:~/akhilesh/lto$ gcc -flto -o nornal myapp.c; nm -C ./nornal |
grep power
0000000000400532 t power
@akhilesh-ubuntu:~/akhilesh/lto$ gcc -o nornal myapp.c; nm -C ./nornal | grep
power
0000000000400532 W power
@akhilesh-ubuntu:~/akhilesh/lto$ 

================================================
@akhilesh-ubuntu:~/akhilesh/lto$ cat myapp.c 
#include <stdio.h>
#include <stdlib.h>
int __attribute__((weak)) power(int x);

int power(int x)
{
  return x*x;
}
int main(int argc, char **argv)
{
  printf("power() = %d\n", power(atoi(argv[1])));
  return 0;
}
