prefetching on pentium 4

[ranjith kumar <ranjit_kumar_b4u@xxxxxxxxxxx>]

Hi,

   1) Will "gcc" insert prefetch instructions
automatically on "pentium 4" processor?
Which flags should be enabled while compiling sothat
gcc  automatically insert prefetch instructions?

2) Or programmer has to include some functions?
   If so, what is the syntax of that function?

Thanks in advance.
