Below but you can see it in the explorer if you comment out line 11 and uncomment 12 https://godbolt.org/z/YGbTsTf1G
if you compile the below with `clang -O3 -mllvm -attributor-enable=module` you'll get no mallocs/free. Calling an indirect function like mymalloc will inline but no longer optimize out malloc/free
```
#include <stdio.h>
#include <stdlib.h>
int getValue() { return 1; }
//void*mymalloc(int i) { return malloc(i); }
void*mymalloc(int i) __THROW __attribute_malloc__
__attribute_alloc_size__ ((1)) __wur { return malloc(i); }
int main(int argc, char *argv[]) {
char*buf=malloc(16);
//char*buf=mymalloc(16);
buf[0] = getValue() + '0';
buf[1] = 0;
puts(buf);
free(buf);
}
```
