Hi,

How can one perform a "rep movsw" in Gcc?  I saw inline code to do a "rep insw"
in machine/cpufunc.h --- is there an equivalent inline macro for "movsw"
that I've missed out?

I cannot use `bcopy' here because I am trying to access a memory mapped I/O
port which requires word accesses (no 8/32 bit accesses are permitted).
