Yes. I tried that, but the compiler complains about the syntax. For that matter it complains about the original Intel syntax as well. > Given the addl above, that should be the AT&T equivalent syntax for > > MOV EAX, [EAX].TSparseList.FList > > One thing that is still bothering me though is that in a 64-bit > application, shouldn't this all be using 64-bit addresses and registers? > I don't know the context of what you're trying to port and Windows may > convenient be giving you addresses that are all clear in the high > 32-bits but it's not safe to assume that in 64-bit code. > > i.e. > > movq TSpareList.Flist(%rax), %rax > > q = quadword (64-bit) where l = longword (32-bit) > > I was wondering about this too. So I suppose I need to include a Freepascal compiler directive, if one exists, for a 32 vs 64 bit OS. Overall I'm inclined to ditch the assembler code by rewriting the ForAll() method and avoid the hassle altogether.
