```
#include <algorithm>
bool f(char* a, char* b) {
return std::equal(a, a+16, b, b+16);
}
bool g(std::byte* a, std::byte* b) {
return std::equal(a, a+16, b, b+16);
}
```
`f` generates `pcmpeqb`. `g` generates a loop. `std::equal` should be aware that `std::byte` is functionally the same as `char`.
#89820 could relate.
