@Jianghibo  hello, may I ask you to verify functionality on the following test

```
#include <stdio.h>

void hello() {
    printf("hello....\n");
}

void execute(void (*callback)()) {
    callback();
}

int main() {
    execute(hello);

    return 0;
}
```
clang -pie -O0 /tmp/icp.c -o /tmp/icp.exe -Wl,-q

what I am waiting from icp=calls optimization that inside execute function will be promotion for hello function based on fdata
