And just let me guess, it'll replace it by a REP STOSB,
and not use STOSW or try to allign the REP to 16 Bit borders...

BTW: above example is exactly one thing why I
hate C.
basicly every compiler will generate a stupid loop, while
in assembly a REP STOSW would do the trick at maximum
speed possible.
Thats why we invented code peeking and code optimiziers,
Hans. A decent optimizer for x86 *will* know to replace
that loop with a REP-prefixed instruction.
