[fpc-devel] Working on FillWord, FillDWord and FillQWord again

[J. Gareth Moreton via fpc-devel]

Hi everyone,

I'm back to working on the x86_64 implementations of FillWord, FillDWord
and FillQWord again due to demand from a couple of end users.

https://bugs.freepascal.org/view.php?id=32637

One question I do have though, because the documentation doesn't bring
it up... must the functions be able to handle memory that isn't aligned
to their respective sizes? That is, should FillWord handle memory that's
not aligned to 2 bytes etc? I would be grateful for an answer, because
if I'm allowed to assume the memory is at least aligned to the size
boundary, I can greatly simplify my assembly language.

There should be no limitations on on alignment. These functions can accept
any address.
