--- Comment #2 from Gonzalo BG <[email protected]> ---
I hope this makes it clearer. The above example is equivalent to:
char h(char* ptr) {
ptr = (char*)(int*)ptr;
return *ptr;
}
> A pointer to an integer is 4-byte aligned:
A load through a pointer to an integer can assume 4-byte alignment.
In the functions f, g, and h that I've shown, there are no such loads anywhere.
h loads through a char*, and f loads through an unsigned char* inside
std::memcpy according to the memcpy spec.
