REQUIRES: x86_64-linux
The input raw profile test has been generated from the following source code:
```
#include <stdlib.h>
#include <string.h>
__attribute__((always_inline))
void qux(int x) {
char *ptr = malloc(x);
memset(ptr, 0, x);
free(ptr);
}
__attribute__((noinline))
void foo(int x){ qux(x); }
__attribute__((noinline))
void bar(int x) { foo(x); }
int main(int argc, char **argv) {
bar(argc);
return 0;
}
```
Compile and run with the following commands:
```
bin/clang -fuse-ld=lld -Wl,--no-rosegment -gmlt -fdebug-info-for-profiling \
-fmemory-profile -mno-omit-leaf-frame-pointer -fno-omit-frame-pointer \
