<div dir="ltr"><div dir="ltr">Hi Ken,<div><br></div><div> I have a suggestion. Instead of initializing WordSize from Smalltalk wordSize I would create two subclasses with a wordSize method, hardcoded as ^4 and ^8 respectively. We want to be able to simulate any of the processors on any platform, hence we can simulate x64 on the 32-bit version and x86 on the 64-bit version as well as 32-bit processors on 32-bit versions and 64-bit processors on 64-bit versions. So structuring the ARM FFI as an abstract subclass with a subclass responsibility for wordSize, along with two subclasses for 64 & 32 bits will give us that flexibility.</div><div><br></div><div>Where a wordSize define would make sense would be in platforms/Cross/plugins/IA32ABI/*ARM*, although you might want to review the code first and see if #ifdef or splitting the files into 32 and 64-bit versions is cleaner.</div><div><br></div></div></div><br><div class="gmail_quote"><div dir="ltr">On Sun, Dec 23, 2018 at 8:06 AM <<a href="mailto:ken.dickey@whidbey.com">ken.dickey@whidbey.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px .8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex;"><div style="font-family:Helvetica, Arial, sans-serif;font-size:12px;"><blockquote><div>Rats! </div><div><br></div><div>Can't even use this webmail thingie...</div><div><br></div><div>[the _other_ changes file]</div><div><br></div><div>Cheers,</div><div>-KenD</div></blockquote></div>
