Cache Flushing instructions

Hi

I am just wondering if the Intel instruction set includes (Dual Core)
an instruction that allows me to flush the INSTRUCTION cache in one
go? I know there is a CFLUSH instruction out there, which allows fine-
grained deleting of single cache lines. However, looping over each
cache line takes quite a while. I think I have found once an
instruction that allows me to flush the whole data cache at once, but
I am more looking into the instruction cache at the moment!

Many thanks!

Just call your broker and say, "Buy Intel!" That'll flush your cash in
a hurry. ;-)

I'd say buying AMD would flush it even faster.
