Hi,

I agree that "const void *" is the better parameter for _mm_prefetch, but it
leads to incompatible code. ICC defines _mm_prefetch as:
void _mm_prefetch(char const *, int)

and MSVC documents it as:
void _mm_prefetch(char * p , int i )

(which is even worse). I would expect the GCC header to use "const char *" too
for the sake of portable code.
